Prepare the Demo

  1. Connect a micro USB cable between the PC host and the MCU-Link USB port (J10) 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:

SPI board to board interrupt master example started!

SPI transfer finished!
