Prepare the Demo

  1. Connect a USB Type-C cable between the host PC and the MCU-Link port on the target 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. Press reset button to begin running the demo. Running the demo ================ The following lines are printed to the serial terminal when the demo program is executed.
