Prepare the Demo

  1. Connect a Type-C USB cable between the host PC and the MCU-Link port(J15) on the target board.

  2. Open a serial terminal on PC for MCU-Link serial device with these settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

  4. Either press the reset button on your board or 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 MCU-Link terminal like:
