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_interrupt_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!
