Standalone mode hardware setup

The MK8000 EVB standalone mode needs two MK8000 EVBs to perform the evaluation. One EVB is configured as an Anchor Role and connected to a 4-element linear array antenna, the other EVB is configured as a Tag role and connected to a single element antenna.

Both EVBs communicate with each other and perform the range and azimuth angle measurement continuously. The results are sent through the serial port and displayed in a command line terminal of the Windows PC.

EVB standalone mode has been pre-set and configured with proper configuration and does not need additional tools or software to control the EVB. It only needs serial port to display the ranging and angle measurement results at Anchor side.

Anchor hardware setup in standalone mode

Table 3 provides the detail of the Anchor side hardware connection in standalone mode and Figure 3 shows the Anchor after connection.

Table 3 Anchor side hardware connection in standalone mode

the EVB will be configured as Anchor (only the EVB with 4-element linear array antenna should use this setting)

Tag hardware setup in standalone mode

Table 4 shows the detail of the Tag hardware connection in standalone mode and Figure 4 shows the tag after connection. In standalone mode, the USB adapter at the tag side is used for power supply only.

MKTool mode hardware setup

The MK8000 EVB MKTool mode needs two MK8000 EVBs and Windows laptops with MKTool software installed. MKTool is a Windows application program developed by MKSEMI and used to configure the chip and the EVB, perform and control the MK8000 chipset evaluation. It has a GUI interface for configuration and results display. Both EVBs need to download the MKTool firmware to perform the test.

MKTool application sends commands and receives responses and measurement results of MK8000 EVB through the serial port. Table 5 listed the details of the hardware connection in MKTool mode for both Anchor and Tag sides.

Table 5 hardware settings for MKTool mode

ISP mode hardware setup

Based on either section 3.4 or 3.5, use flat ribbon wires to connect IO_03 to GND and ensure that the IO_03 is low when the MK8000 EVB is powered on, the EVB enters ISP mode and the firmware can be updated through UART0

Software setup

This chapter provides an overview of software setup of MK8000 EVB. Software setup is needed when MKTool mode is used in the testing and evaluation. There is no need to program the MK8000 EVB if Standalone mode is used in the test and evaluation.

MK8000 Device Description File Installation

MK8000 SDK supports Keil, IAR and GCC IDE platforms for code development and debugging. MK8000 software package includes device description files for all three platforms. For Keil and IAR platforms, device description files need to be installed before using the MK8000 EVB.

Keil Platform

The MK8000 software package includes a self-extract file “MKSEMI.MK800X_DFP.1.0.1.pack” for DFP file installation in Keil environment. By double click the file, the DFP file will be installed automatically.

IAR Platform

The installation of device description file for IAR system is different from that of Keil platform. First, the user needs to unpack the zip file into a temporary folder, then, copy the file in the “config” folder of the temporary folder into the installation directory of IAR, as shown in Figure 5. The device description file for IAR system is then installed.

GCC Platform

There is no need to install configuration or description file in GCC platform.

MK8000 Software Development Kit

MK8000 SDK package includes RTOS, device drivers, peripheral support as well as example codes. Figure 6 shows the SDK directory structure. Users can compile the codes in the example projects and load into the EVB to perform the testing and evaluation. MKSEMI ISPTool software is needed to download the firmware into the EVB. For detail, please refer to ISPTool User Guide [3].

• Standalone mode
  • project: “sdk_folder\boards\mk8000_dk\uwb_examples\aoa_loc”
  • bin file: “sdk_folder\boards\mk8000_dk\uwb_examples\bin_files\aoa_loc.bin”
• MKTool mode project:
  • project: “sdk_folder\boards\mk8000_dk\uwb_examples\uci_test
  • bin file: “sdk_folder\boards\mk8000_dk\uwb_examples\bin_files\uci_test. in”

Standalone Mode

Standalone mode provides a quick demonstration and evaluation of ranging and AoA capability of MK8000 chipset. Figure 9 shows a typical setup of measurement. The tag is set on a plastic stand vertically and connected to a portable battery. The Anchor is set on another plastic stand vertically and connected to a Windows laptop to display the test results by using a console application such as PuTTY. The detailed port configuration is listed in Table 6.

Table 6 Serial port configuration

Since both Anchor and Tag are pre-configured, the measurements will start automatically as soon as both boards are powered up. The console will show the measurement log as shown in Figure 10. The ranging measurement is based on Double-sided Two-way-Ranging protocol, and the angle  measurement is based on Angle of Arrival (AoA) scheme.

MKTool Mode

MKTool mode provides a flexible capability to evaluate the MK8000 chipset. Before the measurement started, load the firmware of Ranging and AoA testing into both Anchor and Tag EVBs, also configure both roles by using the MKTool. Then the test will start and results will be shown in both graphical and data log mode.

Tag configuration

The tag is an MK8000 EVB which connects to single element antenna. To configure the tag, user needs to connect the EVB to the laptop and get a proper COM port number in Windows Device Manager for this device and launch the MKTool application. In MKTool, do the following steps:
