The ADuCM342 is fully integrated, 8 kSPS, data acquisition systems incorporating dual, high performance, Σ-Δ analog-to-digital converters (ADCs), with a 32-bit ARM Cortex ™ -M3 processor and Flash/EE memory on a single chip. The ADuCM342 is complete system solutions for battery monitoring in 12 V automotive applications. The ADuCM342 integrates all of the required features to precisely and intelligently monitor, process, and diagnose 12 V battery parameters including battery current, voltage, and temperature over a wide range of operating conditions.
The ADuCM342 has 128 kB program flash.

GENERAL DESCRIPTION

The EVAL-ADuCM342EBZ development system supports the ADuCM342 and allows a flexible platform for evaluation of the ADuCM342 silicon. The EVAL-ADuCM342EBZ development system allows quick removal and insertion of a device through a 32-lead LFCSP socket. It also provides the connections necessary to allow rapid measurement setups. Switches and LEDs are provided on the applications board to assist in debugging and simple code development. Sample code projects are also provided to show key features of each peripheral and examples of how they can be configured.
This user guide provides step-by-step details of how to set up and configure the example software available on the ADuCM342 Design Tools page.
By working through this user guide, users can start to generate and download their own user code for use in their own, unique end-system requirements.
Full specifications on the ADuCM342 are available in the ADuCM342 data sheet available from Analog Devices, Inc., and must be consulted with this user guide when using the EVALADuCM342EBZ evaluation board.

EVAL-ADUCM342EBZ SOCKETED EVALUATION BOARD SETUP

GETTING STARTED

SOFTWARE INSTALLATION PROCEDURE
Items required to get started are as follows:
► Keil µVision v5 or higher
► CMSIS pack for ADuCM342
► Segger debugger interface driver and utilities
Complete the steps described in this section before plugging any of the USB devices into the PC.
Support files for Keil are provided at the ADuCM342 Design Tools page. For Keil v5 upwards, CMSIS pack is required and is available on the ADuCM342 product pages.
INSTALLING
To install the software, do the following steps:

1. Close all open applications.
2. From the Keil website, download and install the Keil µVision v5 (or higher).
3. From the Segger website, download and install the latest J- Link software & documentation pack for Windows.
4. From the ADuCM342 product page, download the CMSIS pack for the ADuCM342.

VERIFYING THE J-LINK DRIVER
To install the J-Link driver, do the following steps:

1. Follow the sequence of instructions provided by Segger to download and install the J-Link driver.
2. When the software installation is complete, plug the debugger/programmer into the USB port of your PC using the USB cable supplied.
3. Verify that the emulator board appears in the Windows Device Manager window® (see Figure 2).
   

CONNECT THE DEVELOPMENT SYSTEM

To connect the development system, do the following steps:

1. Ensuring correct orientation, insert an ADuCM342 device. Note that a dot in the corner shows the Pin 1 of the device. The dot on the device must be orientated with the dot on the socket, as shown in Figure 3.
2. Connect the debugger/programmer, noting the correct orientation as shown in Figure 4.
3. Connect a 12 V supply between V and GND.
4. Ensure that the board jumpers are in position, as shown in BAT Figure 1.
5. Ensure that the GPIO5 jumper is in place. The GPIO5 jumper is used by the on-board kernel to determine program flow after a reset. For more details, see the Kernel section in the ADuCM342 hardware reference manual.
6. Press RESET.

JUMPER FUNCTIONALITY
Table 1. Jumper Functionality

device.
J4, GPIO1, GPIO2, GPIO3| These jumpers connect the LEDs to the GPIO1, GPIO2, and GPIO3 pins of the device.
J4, GPIO4| These jumpers connect the SW2 push button to the GPIO4 pin of the device.
J4, GPIO5| This jumper ties the GPIO5 pin of the device to GND. This jumper must be connected when programming the device or when accessing
through serial wire debug (SWD).
VBAT_3V3_REG| This jumper enables the 3.3 V regulator on the underside of the printed circuit board (PCB). This jumper powers the LEDs, or an additional
3.3 V source.
LIN| This jumper is not inserted and connected through the 0 Ω link. This jumper can disconnect the LIN terminal (green banana socket) from
the device when the 0 Ω link is removed.
IDD, IDD1| These jumpers are not inserted and connected through the 0 Ω link. This jumper allows the insertion of an ammeter in series with the
VBAT supply through the IDD+/IDD sockets for current measurement when the 0 Ω link is removed.
VB| This jumper is not inserted and is connected through the 0 Ω link. This jumper disconnects the VBAT supply from the device VBAT input
when the 0 Ω link is removed.
AUX_VIN| This jumper is not inserted. The VINx_AUX device pins are connected to GND through the 0 Ω link.
VIN_SENS| This jumper is not inserted. This jumper connects a sensor to the VINx_AUX input of the device when the 0 Ω link connecting the
VINx_AUX to GND is removed.
IIN| This jumper shorts the inputs of the current channel ADC.
IIN_MC| This jumper is not inserted. This jumper connects to the signal at the IIN+ and IIN− pins of the device.
AUX_IIN| This jumper is not inserted. The IINx_AUX device pins are connected to GND through the 0 Ω link.
