Hardware requirements

  • Micro USB cable

  • EVK-MIMXRT595 board

  • Personal Computer

Board settings

The example provides 2 options of SPI interfaces in communication.

  1. SPI5 (default, normal SPI: #define USE_HS_SPI 0)

  2. SPI14 (optional, high speed SPI: #define USE_HS_SPI 1) User can change the USE_HS_SPI value in spi_polling_b2b_transfer_slave.c to choose different SPI interface.

Connect SPI master on board to SPI slave on other board. Only 1 set of signals need to be connected, either SPI5 or SPI14 depending on the USE_HS_SPI setting. NOTE: To use SPI14 on EVK board, please connect JP32 1-2.

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J40) on the board

  2. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

  4. Launch the debugger in your IDE to begin running the demo.

Running the demo

When the demo runs successfully, the log would be seen on the terminal like:

Slave is working....

Succeed!
