Prepare the Demo#

Note: MCUXpresso IDE project default debug console is semihost

  1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (P6) on the board

  2. Open a serial terminal with the following settings (See Appendix A in Getting started guide for description how to determine serial port number):

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

  4. Reset the SoC and run the project.

Running the demo#

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

SPI one board interrupt example started!

SPI transfer finished!
