UG477: Z-Wave 700 ZGM130S Long Range Radio Board User’s Guide
Introduction
1. Introduction
The ZGM130S Wireless Gecko SiP Module is featured on a radio board that plugs directly into a Wireless Starter Kit (Wireless STK) Mainboard or a Wireless Pro Kit Mainboard. The mainboards feature several tools for easy evaluation and development of wireless applications. An on-board J-Link debugger enables programming and debugging on the target device over USB or Ethernet. The Advanced Energy Monitor (AEM) offers real-time current and voltage monitoring. A virtual COM port interface (VCOM) provides an easyto-use serial port connection over USB or Ethernet. The Packet Trace Interface (PTI) offers invaluable debug information about transmitted and received packets in wireless links. All debug functionality, including AEM, VCOM, and PTI, can also be used towards external target hardware instead of the attached radio board.
To further enhance its usability, the mainboard contains sensors and peripherals that demonstrate some of the many capabilities of the ZGM130S. The mainboard also has a 20-pin EXP header which can be used for connecting EXP boards to the kit or for easy connection to I/Os on the radio board target IC.
1.1 Radio Boards
A Wireless Starter Kit consists of one or more mainboards and radio boards that plug into the mainboard. Different radio boards are available, each featuring different Silicon Labs devices with different operating frequency bands. Because the mainboards are designed to work with different radio boards, the actual pin mapping from a device pin to a mainboard feature is done on the radio board. This means that each radio board has its own pin mapping to the Wireless STK features, such as buttons, LEDs, the display, the EXP header, and the breakout pads. Because this pin mapping is different for every radio board, it is important to consult the correct document, which shows the kit features in context of the radio board plugged in.
1.2 Mainboards
The ZGM130S Z-Wave Long Range Radio Board (BRD4207A) can be used with either a Wireless Starter Kit Mainboard (BRD4001A) or a Wireless Pro Kit Mainboard (BRD4002A). The Wireless Pro Kit Mainboard is the successor to the Wireless Starter Kit Mainboard, which comes with some improvements and added features including increased AEM measurement range and sample rate, variable VMCU voltage, joystick, a logic analyzer, and a Mini Simplicity Connector. Kit features, such as the Si7021 sensor and the EXP header, are available on the same ZGM130S pins regardless of the mainboard being used, but the pinout to the breakout pads differs. The combination of the ZGM130S Z-Wave Long Range Radio Board with either one of these mainboards is hereby referred to as a Wireless Starter Kit as the figure below illustrates.

The EXP header is an angled, 20-pin expansion header that allows connection of peripherals or plugin boards to the kit. It is located on the right-hand side of the mainboard and contains several I/O pins that can be used with most of the ZGM130S Wireless Gecko’s features. Additionally, the VMCU, 3V3, and 5V power rails are also exposed.
The connector follows a standard which ensures that commonly used peripherals, such as a SPI, a UART, and an I2C bus, are available on fixed locations in the connector. The rest of the pins are used for general purpose IO. This allows the definition of expansion boards (EXP boards) that can plug into several different Silicon Labs Starter Kits.
The figure below shows the pin assignment of the EXP header. Because of limitations in the number of available GPIO pins, some of the EXP header pins are shared with kit features.

3.5 Logic Analyzer Connector
The Wireless Pro Kit Mainboard includes an on-board, eight-channel logic analyzer. It enables four digital signals to be sampled and displayed in Simplicity Studio, in addition to the state of the on-board user interface LEDs and buttons. The logic analyzer is a good tool for correlating specific events to the AEM energy profile and packet trace data as these are time- synchronized and can be visualized together. The sampling rate of 100 kHz limits its use in decoding digital protocols like I2C or SPI.
The logic analyzer connector is situated on the top right side of the Wireless Pro Kit Mainboard. Four signals (channel 0-3) can be connected to the logic analyzer using this connector and the test probes that are obtainable through the “Si-DA001A Pro Kit Mainboard Accessory Kit”. The test probes can be connected to the kit itself or on an external board connected to the Wireless Pro Kit Mainboard. Note that in both cases the connected signals must be digital, and the voltages referenced to ground and VMCU on the Wireless Pro Kit Mainboard. The table below gives an overview of the logic analyzer signals.
Note: The logic analyzer is only available on the Wireless Pro Kit Mainboard (BRD4002A). Using the external signals requires test probes which are obtainable through the “Si-DA001A Pro Kit Mainboard Accessory Kit”.

3.6 Debug Connector
The debug connector serves multiple purposes based on the “debug mode” setting which can be configured in Simplicity Studio. When the debug mode is set to “Debug IN”, the debug connector can be used to connect an external debugger to the ZGM130S on the radio board. When set to “Debug OUT”, this connector allows the kit to be used as a debugger towards an external target. When set to “Debug MCU” (default), the connector is isolated from both the on-board debugger and the radio board target device.
Because this connector is electronically switched between the different operating modes, it can only be used when the board controller is powered (i.e., J-Link USB cable connected). If debug access to the target device is required when the board controller is unpowered, connect directly to the appropriate breakout pins.
The pinout of the connector follows that of the standard ARM Cortex Debug+ETM 19-pin connector. The pinout is described in detail below. Even though the connector has support for both JTAG and ETM Trace, it does not necessarily mean that the kit or the on-board target device supports these features.

Note: The pinout matches the pinout of an ARM Cortex Debug+ETM connector, but these are not fully compatible because pin 7 is physically removed from the Cortex Debug+ETM connector. Some cables have a small plug that prevents them from being used when this pin is present. If this is the case, remove the plug or use a standard 2×10 1.27 mm straight cable instead.

3.9 Debug Adapter
The BRD8010A STK/WSTK Debug Adapter is an adapter board which plugs directly into the debug connector and the Simplicity Connector on the mainboard. It combines selected functionality from the two connectors to a smaller footprint 10-pin connector, which is more suitable for space-constrained designs.
For versatility, the debug adapter features three different 10-pin debug connectors: · Silicon Labs Mini Simplicity Connector · ARM Cortex 10-pin Debug Connector · Silicon Labs ISA3 Packet Trace
The ARM Cortex 10-pin Debug Connector follows the standard Cortex pinout defined by ARM and allows the Wireless STK to be used to debug hardware designs that use this connector.
The ISA3 connector follows the same pinout as the Packet Trace connector found on the Silicon Labs Ember Debug Adapter (ISA3). This enables using the Wireless STK to debug hardware designs that use this connector.
The Mini Simplicity Connector is designed to offer advanced debug features from the kit on a 10-pin connector. The connector has the same pinout and functionality as described in 3.8 Mini Simplicity Connector. It is only necessary to use the debug adapter to get access to the Mini Simplicity Connector when using the Wireless STK Mainboard (BRD4001A). If using the Wireless Pro Kit Mainboard (BRD4002A), use the Mini Simplicity Connector on the mainboard instead.

4.1 Radio Board Power Selection

The ZGM130S on a Wireless STK can be powered by one of these sources:

· The debug USB cable · A 3 V coin cell battery · A USB regulator on the radio board (for devices with USB support only)

The power source for the radio board is selected with the slide switch in the lower left corner of the Wireless STK Mainboard or the Wireless Pro Kit Mainboard. The figure below shows how the different power sources can be selected with the slide switch.

Figure 4.1. Power Switch
Note: The middle position is denoted by “USB” on the Wireless STK Mainboard, while it is denoted by “SELF” on the Wireless Pro Kit Mainboard. The slide switch functions the same on both mainboards.
Note: The AEM can only measure the current consumption of the ZGM130S when the power selection switch is in the AEM position.
AEM position: With the switch in the AEM position, a low noise LDO on the mainboard is used to power the radio board. This LDO is again powered from the debug USB cable. The AEM is now also connected in series, allowing accurate high speed current measurements and energy debugging/profiling.
USB position: With the switch in the USB position, radio boards with USB- support can be powered by a regulator on the radio board itself. BRD4207A does not contain a USB regulator, and setting the switch in the USB position will cause the ZGM130S to be unpowered.
BAT position: With the switch in the BAT position, a 20 mm coin cell battery in the CR2032 socket can be used to power the device. With the switch in this position, no current measurements are active. This is the switch position that should be used when the radio board is powered with an external power source. The Wireless Pro Kit Mainboard (BRD4002A) features an additional 2-pin JST connector connected in paralell to the CR2032 socket that can be used with an external power source between 1.8 V and 3.6 V instead of a coin cell. The coin cell battery is not protected from reverse current, and it is therefore important to remove the coin cell battery from the CR2032 socket if applying external power.
Note: The current sourcing capabilities of a coin cell battery might be too low to supply certain wireless applications.

Power Supply and Reset
4.2 Kit Power
There are normally two main contributions to the power consumption from the mainboard USB connector, i.e., two main current paths:
· One being monitored by the AEM that goes to the target power domain (VMCU) · One that goes to the board controller power domain
While the current consumption of the board controller section is fairly deterministic and stable, the current consumption connected to the target’s power domain (VMCU) varies widely depending on the application and the slide switch position. Typically, the board controller power domain draws 200 mA on the Wireless Starter Kit Mainboard (BRD4001A) and 250 mA on the Wireless Pro Kit Mainboard (BRD4002A). The mainboards use linear regulators, and the recommended input voltage is 4.4 – 5.25 V. Use a USB host or power supply and cables that can deliver at least the total amount of current required by the kit.
The 5V net exposed on the breakout pads, EXP header, and radio board is also sourced from the mainboard USB connector when the power select switch is in the AEM position. The 3V3 net exposed on the same peripherals is always sourced from the mainboard USB connector. The current consumption of these nets must be included in the total current consumption of the kit if these are utilized.
4.2.1 Board Controller Power
The board controller is responsible for important features, such as the debugger and the AEM, and is powered exclusively through the USB port in the top left corner of the board. This part of the kit resides on a separate power domain, so a different power source can be selected for the target device while retaining debugging functionality. This power domain is also isolated to prevent current leakage from the target power domain when power to the board controller is removed.
The board controller power domain is not influenced by the position of the power switch.
The kit has been carefully designed to keep the board controller and the target power domains isolated from each other as one of them powers down. This ensures that the target ZGM130S device will continue to operate in the BAT mode.
4.2.2 AEM Power
The supply for the target power domain (VMCU) is a linear regulator integrated with the AEM described in Section 8. Advanced Energy Monitor when the power select switch is in the AEM position. The output voltage of the regulator is fixed to 3.3 V on the Wireless STK Mainboard (BRD4001A), while it can be adjusted between 1.8 V and 3.6 V on the Wireless Pro Kit Mainboard (BRD4002A) using the admin console.
The output current on the Wireless Pro Kit Mainboard (BRD4002A) is limited by an overcurrent protection (OCP) function, which depends on the programmed VMCU voltage: OCP (A) VMCUSET (V) x 0.2 (A/V). Approaching or exceeding the OCP limit is not recommended as the output voltage will be pulled low, which causes loss of function.
The maximum recommended output current on the Wireless STK Mainboard (BRD4001A) is 300 mA.
4.3 ZGM130S Reset
The ZGM130S SiP Module can be reset by a few different sources: · A user pressing the RESET button · The on-board debugger pulling the #RESET pin low · An external debugger pulling the #RESET pin low
In addition to the reset sources mentioned above, a reset to the ZGM130S will also be issued during board controller boot-up. This means that removing power to the board controller (unplugging the J-Link USB cable) will not generate a reset but plugging the cable back in will as the board controller boots up.

Moving the joystick around connects different pull-down resistors to the joystick output, which together with the pull-up resistor on VMCU, creates different output voltages, Vo, that can be read using the ADC on the ZGM130S.
Note: The PD12 pin on the ZGM130S is also used for the blue RGB LED (UIF_LED_B) on this kit. Both the joystick and the blue RGB LED (UIF_LED_B) can be used, but not at the same time.

5.4 Memory LCD-TFT Display
A 1.28-inch SHARP Memory LCD-TFT is available on the kit to enable interactive applications to be developed. The display has a high resolution of 128 x 128 pixels and consumes very little power. It is a reflective monochrome display, so each pixel can only be light or dark, and no backlight is needed in normal daylight conditions. Data sent to the display is stored in the pixels on the glass, which means no continuous refreshing is required to maintain a static image.
The display interface consists of a SPI-compatible serial interface and some extra control signals. Pixels are not individually addressable, instead data is sent to the display one line (128 bits) at a time.
The Memory LCD-TFT display is shared with the kit’s board controller, allowing the board controller application to display useful information when the user application is not using the display. The user application always controls ownership of the display with the DISP_ENABLE signal: · DISP_ENABLE = LOW: The board controller has control of the display · DISP_ENABLE = HIGH: The user application (ZGM130S) has control of the display
Power to the display is sourced from the target application power domain when the ZGM130S controls the display and from the board controller’s power domain when the DISP_ENABLE line is low. Data is clocked in on DISP_SI when DISP_CS is high, and the clock is sent on DISP_SCLK. The maximum supported clock speed is 1.1 MHz.
DISP_EXTCOMIN is the “COM Inversion” line. It must be pulsed periodically to prevent static build-up in the display itself. Refer to the LS013B7DH03 documentation for more information on driving the display.

5.5 Si7021 Relative Humidity and Temperature Sensor
The Si7021 I2C relative humidity and temperature sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I2C Interface. The patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables the construction of low-power, monolithic CMOS Sensor ICs with low drift and hysteresis, and excellent long term stability.
The humidity and temperature sensors are factory-calibrated and the calibration data is stored in the on-chip non-volatile memory. This ensures that the sensors are fully interchangeable with no recalibration or software changes required.
The Si7021 is available in a 3×3 mm DFN package and is reflow solderable. It can be used as a hardware and software-compatible drop-in upgrade for existing RH/temperature sensors in 3×3 mm DFN-6 packages, featuring precision sensing over a wider range and lower power consumption. The optional factory-installed cover offers a low profile, convenient means of protecting the sensor during assembly (e.g., reflow soldering) and throughout the life of the product, excluding liquids (hydrophobic/oleophobic) and particulates.
The Si7021 offers an accurate, low-power, factory-calibrated digital solution ideal for measuring humidity, dew point, and temperature in applications ranging from HVAC/R and asset tracking to industrial and consumer platforms.
The I2C bus used for the Si7021 is shared with the EXP header. The temperature sensor is normally isolated from the I2C line. To use the sensor, SENSOR_ENABLE (PD15) must be set high. When enabled, the sensor’s current consumption is included in the AEM measurements.

When connecting via USB, the device should automatically show up as a COM port. The actual device name that is associated with the kit depends on the operating system and how many devices are or have been connected previously. The following are examples of what the device might show up as: · JLink CDC UART Port (COM5) on Windows hosts · /dev/cu.usbmodem1411 on macOS · /dev/ttyACM0 on Linux
Data sent by the target device into the VCOM interface can be read from the COM port, and data written to the port is transmitted to the target device. Connecting to the Wireless STK on port 4901 gives access to the same data over TCP/IP. Data written into the VCOM interface by the target device can be read from the socket, and data written into the socket is transmitted to the target device. Note: Only one of these interfaces can be used at the same time, with the TCP/IP socket taking priority. This means that if a socket is connected to port 4901, no data can be sent or received on the USB COM port.
5.6.2 Serial Configuration
By default, the VCOM serial port is configured to use 115200 8N1 (115.2 kbit/s, 8 data bits, 1 stop bit), with flow control disabled/ignored. The configuration can be changed using the admin console:
WPK> serial vcom config Usage: serial vcom config [–nostore] [handshake <rts/cts/rtscts/disable/auto>] [speed <9600,921600>] Using this command, the baud rate can be configured between 9600 and 921600 bit/s, and hardware handshake can be enabled or disabled on either or both flow control pins.

5.6.3 Hardware Handshake
The VCOM peripheral supports basic RTS/CTS flow control.
VCOM_CTS (target clear to send) is a signal that is output from the board controller and input to the target device. The board controller de-asserts this pin whenever its input buffer is full and it is unable to accept more data from the target device. If hardware handshake is enabled in the target firmware, its UART peripheral will halt when data is not being consumed by the host. This implements end-to-end flow control for data moving from the target device to the host.
VCOM_CTS is connected to the RTS pin on the board controller and is enabled by setting handshake to either RTS or RTSCTS using the “serial vcom config” command.
VCOM_RTS (target request to send) is a signal that is output from the target device and input to the board controller. The board controller will halt transmission of data towards the target if the target device de-asserts this signal. This gives the target firmware a means to hold off incoming data until it can be processed. Note that de-asserting RTS will not abort the byte currently being transmitted, so the target firmware must be able to accept at least one more character after RTS is de-asserted.
VCOM_RTS is connected to the CTS pin of the board controller. It is enabled by setting handshake to either CTS or RTSCTS using the “serial vcom config” command in the admin console. If CTS flow control is disabled, the state of VCOM_RTS will be ignored and data will be transmitted to the target device anyway.

7. Board Controller

UG477: Z-Wave 700 ZGM130S Long Range Radio Board User’s Guide
Board Controller

7.1 Introduction
The Wireless STK Mainboard and the Wireless Pro Kit Mainboard contain a dedicated microcontroller for some of the advanced kit features provided. This microcontroller is referred to as the board controller and is not programmable by the user. The board controller acts as an interface between the host PC and the target device on the radio board, as well as handling some housekeeping functions on the board.
Note: This chapter describes the board controller on both the Wireless Starter Kit Mainboard and the Wireless Pro Kit Mainboard. There might be slight differences between these two boards, such as the exact menu and format on the admin console, not highlighted in this chapter. The logic analyzer is furthermore only available on BRD4002A.

Some of the kit features actively managed by the board controller are:
· The on-board debugger, which can flash and debug both on-board and external targets. · The Advanced Energy Monitor, which provides real-time energy profiling of the user application. · The Packet Trace Interface, which is used in conjunction with PC software to provide detailed insight into an active radio network. · The logic analyzer, which can capture digital signals time- synchronized to the energy profiling and packet trace data. · The Virtual COM Port and Virtual UART interfaces, which provide ways to transfer application data between the host PC and the
target processor. · The admin console, which provides configuration of the various board features.
Silicon Labs publishes updates to the board controller firmware in the form of firmware upgrade packages. These updates may enable new features or fix issues. See Section 10.1 Firmware Upgrades for details on firmware upgrade.

7.2 Admin Console The admin console is a command line interface to the board controller on the kit. It provides functionality for configuring the kit behavior and retrieving configuration and operational parameters.
7.2.1 Connecting The admin console is available when the Wireless STK is connected to Ethernet using the Ethernet connector in the top left corner of the mainboard. See Section 9.1.2 Ethernet Interface for details on the Ethernet connectivity. Connect to the admin console by opening a telnet connection to the kit’s IP address, port number 4902. When successfully connected, a WPK> prompt is displayed.

This means that running pti enable will enable packet trace.

7.2.3 Command Examples

PTI Configuration pti config 0 efruart 1600000 Configures PTI to use the “EFRUART” mode at 1.6 Mb/s.

Serial Port Configuration serial config vcom handshake enable Enables hardware handshake on the VCOM UART connection.

7.3 Virtual UART
The Virtual UART (VUART) interface provides a high-performance application data interface that does not require additional I/O pins apart from the debug interface.
The Wireless STK makes the VUART interface available on TCP/IP port 4900.

7.3.1 Target-to-Host
Target-to-host communication utilizes the SWO-pin of the debug interface through the ITM debug peripheral. This approach allows a sleepy target device to enter all energy modes and still wake up intermittently to send debug information. The baud rate of the SWO data is locked to 875 kHz.
VUART utilizes ITM stimulus port 0 for general purpose printing. Silicon Labs’ networking stacks utilize ITM stimulus port 8 for debug printing. The data on port 8 is encapsulated in additional framing and will also appear in the Simplicity Studio Network Analyzer.

Rev. 2.1 | 29

UG477: Z-Wave 700 ZGM130S Long Range Radio Board User’s Guide
Board Controller
7.3.2 Host-to-Target
Host-to-target communication utilizes SEGGER’s Real Time Transfer (RTT) technology. A full explanation of how this works can be found in J-Link/J-Trace User Guide (UM08001). Briefly summarized, RTT consists of a structure called the RTT Control Block, which is located in RAM. This control block points to circular buffers that the debugger can write data into. The target application can then read data out of this circular buffer.
The board controller will start searching for the RTT Control Block upon receiving data on TCP/IP port 4900. If the board controller is unable to locate the RTT Control Block, it will return an error message on the same connection. For the board controller to be able to locate the RTT Control Block, it has to be aligned on a 1024-byte boundary in RAM.
After initializing the RTT connection, the target will only enter emulated EM2 and EM3 where the power consumption remains similar to EM1. This is because RTT utilizes the debug interface, which requires use of high-frequency oscillators. Energy modes EM4S and EM4H will work as normal. When debugging energy consumption, it is therefore important to not send data on TCP/IP port 4900 as not to instantiate the RTT connection.

7.3.3 Limitations
· Because the SWO-connection can be disabled by the debugger at will, it is important for the target application to verify that SWO is enabled and configured before each transmission on the interface.
· After initializing host-to-target communication over RTT by sending data on TCP/IP port 4900, the target application will be unable to enter EM2 and EM3. This is because RTT utilizes the debug connection of the target.
· VUART might not work reliably during an active debugging session. This is because there is contention over the target’s debug interface. The board controller will defer accessing the target until it is made available by the host debugger.
· VUART is designed with the assumption that only the board controller will access the RTT control block. If the target application uses RTT for other purposes, such as Segger SystemView, refrain from using VUART.

7.3.4 Troubleshooting

Problem

Solution

No data received after ending a debug session.
No data received after flashing a new application.

After certain debugger operations, the host computer manually disables SWO on the target to conserve power. This might cause SWO data to not appear if the target application initialized SWO before the debugger has disconnected. Either press the RESET button on the Wireless Starter Kit to reset the target application or make sure that the target application verifies that SWO is enabled and configured before sending any data.

Other issues

Disconnect from TCP port 4900, press the RESET button on the kit, then reconnect to 4900. If this does not fix the issue, try to restart the kit by unplugging and replugging the USB cable.

8. Advanced Energy Monitor

UG477: Z-Wave 700 ZGM130S Long Range Radio Board User’s Guide
Advanced Energy Monitor

8.1 Introduction
Any embedded developer seeking to make their embedded code spend as little energy as the underlying architecture supports needs tools to easily and quickly discover inefficiencies in the running application. This is what the Simplicity Energy Profiler is designed to do. In real-time, the Energy Profiler will graph and log current as a function of time while correlating this to the actual target application code running on the ZGM130S. There are multiple features in the profiler software that allow for easy analysis, such as markers and statistics on selected regions of the current graph or aggregate energy usage by different parts of the application. The Energy Profiler is available through Simplicity Studio.

8.2 Code Correlation
By using the Energy Profiler, current consumption and voltage can be measured and linked to the actual code running on the ZGM130S in realtime. The Energy Profiler gets its data from the board controller on the mainboard through the Advanced Energy Monitor (AEM). The current signal is combined with the target processor’s Program Counter (PC) sampling by utilizing a feature of the ARM CoreSight debug architecture, and the Instrumentation Trace Macrocell (ITM) block can be programmed to sample the MCU’s PC at periodic intervals and output these over SWO pin ARM devices. When these two data streams are fused and correlated with the running application’s memory map, an accurate statistical profile can be built that shows the energy profile of the running application in real-time.

8.3 AEM Circuit
The AEM circuit on the Wireless Pro Kit Mainboard (BRD4002A) and the Wireless STK Mainboard (BRD4001A) measures the current through a sense resistor inside the feedback loop of a low-dropout regulator (LDO). The output voltage of this LDO powers the ZGM130S when the power slide switch is in the AEM position. AEM usage on both mainboards is similar, but the implementation and perfomance on the Wireless Pro Kit Mainboard (BRD4002A) has some key differences, including the utilization of two sense resistors instead of one, and a different LDO, which is explained in Section 8.3.1 AEM Details. The AEM implementation on the Wireless Pro Kit Mainboard (BRD4002A) is shown in the figure below.

Note: The AEM circuit only works when the kit is powered and the power switch is in the AEM position.

0 – 95 mA

Wireless Pro Kit Mainboard (BRD4002A) AEM Design Details
The AEM circuitry on the Wireless Pro Kit Mainboard is capable of measuring current signals in the range of approximately 0.1 µA to 495 mA. This is accomplished through a combination of a highly capable current sense amplifier, multiple sense resistors and gain stages, and signal processing within the kit’s board controller before the current sense signal is read by a host computer with 100 kHz sample rate for display and/or storage. Averaging on the output data may be required to achieve sufficient accuracy in some situations, such as low currents, which can be traded for lower bandwidth. High current applications require that the regulator is able to supply enough current as described in Section 4.2 Kit Power.
At low currents the current sense amplifier measures the voltage drop over a 10.5 resistive path. The gain stage further amplifies this voltage with two different parallel gain settings to obtain two current ranges. The transition between these two ranges occurs around 150 µA. When the current exceeds a threshold, which is typically between 10 and 30 mA, the AEM circuitry switches from the 10.5 resistive path to a 0.5 sense resistor and is now capable of measuring currents up to approximately 495 mA. Should the current drop below the threshold again, the sense resistor is changed back to the 10.5 resistive path and the AEM is back to using two different gain stages depending on whether the current is above or below 150 µA.
The expected typical accuracy of the AEM on the Wireless Pro Kit Mainboard is within 1 %, except for currents in the low tens of microamps where offset errors start to dominate. In this low current region, the expected typical accuracy is some hundred nanoamps. At kit power-up or on a power-cycle, an automatic AEM calibration is performed which compensates for offset errors in the current sense amplifiers. To achieve the stated accuracy, averaging of the AEM output data is required in certain situations (typically at low currents and close to the bottom of the measurement ranges) to reduce noise. Averaging can be applied in Energy Profiler to suit different requirements during or after the acquisition. The analog bandwidth of the measurement circuit depends on multiple factors, such as output current and capacitance on the VMCU net, and may be lower than the output data rate. Generally, higher output current and lower capacitance on VMCU gives a higher analog bandwidth.
Wireless STK Mainboard (BRD4001A) AEM Design Details
The AEM circuitry on the Wireless STK Mainboard works conceptually in a similar way to the implementation on the Wireless Pro Kit Mainboard except for two key differences: it uses only one 2.35 sense resistor and the low-dropout regulator (LDO) is different. For details about the two implementations, the reader is encouraged to see the schematics.
The AEM on the Wireless STK Mainboard is capable of measuring currents in the range of 0.1 µA to 95 mA. The second stage amplifier amplifies the signal with two different gain settings with the transition occurring around 250 µA. For currents above 250 µA, the AEM is accurate within 0.1 mA. When measuring currents below 250 µA, the accuracy increases to 1 µA. Even though the absolute accuracy is 1 µA in the sub 250 µA range, the AEM can detect changes in the current consumption as small as 0.1 µA. It is possible to source currents above the measurement range as decribed in Section 4.2 Kit Power. The board controller outputs the AEM data with 10 kHz sample rate.

On-Board Debugger
9. On-Board Debugger
The Wireless Pro Kit Mainboard and the Wireless STK Mainboard contain an integrated debugger, which can be used to download code and debug the ZGM130S. In addition to programming a target on a plug-in radio board, the debugger can also be used to program and debug external Silicon Labs EFM32, EFM8, EZR32, and EFR32 devices connected through the debug connector.
The debugger supports three different debug interfaces for Silicon Labs devices: · Serial Wire Debug is supported by all EFM32, EFR32, and EZR32 devices · JTAG is supported by EFR32 and some EFM32 devices · C2 Debug is supported by EFM8 devices
For debugging to work properly, make sure the selected debug interface is supported by the target device. The debug connector on the board supports all three of these modes.
9.1 Host Interfaces The Wireless STK supports connecting to the on-board debugger using either Ethernet or USB.
Many tools support connecting to a debugger using either USB or Ethernet. When connected over USB, the kit is identified by its J-Link serial number. When connected over Ethernet, the kit is normally identified by its IP address. Some tools also support using the serial number when connecting over Ethernet; however, this typically requires the computer and the kit to be on the same subnet for the discovery protocol (using UDP broadcast packets) to work.
9.1.1 USB Interface The USB interface is available whenever the USB connector on the left-hand side of the mainboard is connected to a computer.
9.1.2 Ethernet Interface The Ethernet interface is available when the mainboard Ethernet connector in the top left corner is connected to a network. Normally, the kit will receive an IP address from a local DHCP server, and the IP address is printed on the LCD display. If your network does not have a DHCP server, you need to connect to the kit via USB and set the IP address manually using Simplicity Studio, Simplicity Commander, or J-Link Configurator.
For the Ethernet connectivity to work, the kit must still be powered through the mainboard USB connector.
9.1.3 Serial Number Identification All Silicon Labs kits have a unique J-Link serial number which identifies the kit to PC applications. This number is 9 digits and is normally on the form 44xxxxxxx.
The J-Link serial number is normally printed at the bottom of the kit LCD display.

9.2 Debug Modes
The kit can be used in various debug modes as explained in this chapter. The on-board debugger can be used to debug the ZGM130S on the radio board, or it can be used to debug a supported external target board using either the debug connector or the Mini Simplicity Connector. An external debugger can furthermore be used to debug the ZGM130S on the radio board using the debug connector. Selecting the active debug mode is done in Simplicity Studio.
Note: The Wireless Starter Kit Mainboard (BRD4001A) does not feature a Mini Simplicity Connector; therefore, debugging an external target board directly over the Mini Simplicity Connector is not supported on this mainboard. However, it is possible to debug an external target that uses a Mini Simplicity Connector from the Wireless Starter Kit Mainboard by using a BRD8010A STK/WSTK Debug Adapter.
