The Arduino interface can be found on many microprocessor development platforms and are a great way to begin prototyping a design. The EVAL-M355-ARDZ-INT was developed to enable quick and easy connection of the ADuCM355 based sensor boards to the EVAL-ADICUP3029 development board or any equivalent Arduino MCU controller boards. This allows for testing the functionality as well as the performance of the circuit using a controlled evaluation environment.
Pictured above is the EVAL-M355-ARDZ-INT interposer board which was developed to quickly and easily connect ADICUP3029 development board or any equivalent Arduino MCU controller boards.
The EVAL-M355-ARDZ-INT takes customized connectors to the ADuCM355 sensor surf boards, and allows up to four channels of sensor boards to be used with the EVAL-ADICUP3029 platform. Because the ADICUP3029 is an Arduino form factor compatible development board, many other equivalent Arduino form factor compatible development board can also be used simply by writing custom code. Below is the pinout of the custom connector of the sensor surf boards.
EVAL-M355-ARDZ-INT provides 3.3V power supply to an ADuCM355 base sensor shield board modules from ADICUP3029 development board or any equivalent Arduino MCU controller boards.
The EVAL-M355-ARDZ-INT can accommodate up to four ADuCM355 sensor surf board at the same time. The software and hardware support communications via:
Arduino shield boards follow a standard pinout for the Arduino form factor compatible development boards.
The debugger from the ADICuP3029 can be used and can be linked to the interposer board through the SWD_DEBUG (P10). The user can use a standard 10-pin ARM JTAG/SWD ribbon cable to connect to the ADICuP3029 debugger to the interposer board.
There is a way to cut the SWD traces on the ADICUP3029 board right at the break away section of the board. By cutting the trace for the SWD_DIO, SWD_CLK and SWD_RST located near P12. There are two(2) traces on the top of the board that must be cut using a knife, and one(1) trace found at the bottom of ADICUP3029 (the outter most trace), This allows customers to program both the ADICUP3029 and M355-INT boards without losing the ability to stream serial data back to the USB port.
The EVAL-M355-ARDZ-INT can accommodate up to four ADuCM355 sensor surf board and communicate to these boards at the same time through SPI communication protocol. Debugging and programming is being done independently for each channel by configuring the following switch matrix labeled SWD_DEBUG_CH_SW (S1) found on the silkscreen of the interposer board and with a corresponding LED indicator of which senor board is being accessed.
By default the ADuCM355 sensor surf boards come preloaded with SPI communication protocol back to the ADICUP3029.
Sensor shield board can also communicated either through UART or I2C depending on the firmware loaded on the sensor surf board and on the switch (S2) located on the EVAL-M355-ARDZ-INT.
It's important that the software and the hardware are set to the same digital communication protocol, so you receive and display data.
If you are using the ADICUP3029 development board with the EVAL-M355-ARDZ-INT adaptor board, please use the following setup procedure:
