Prepare the Demo

  1. Connect 12V~20V power supply and J-Link Debug Probe to the board, switch SW301 to power on the board.

  2. Connect a USB Type-C cable between the host PC and the J1401 USB port on the target board.

  3. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  4. Download the program to the target board.

  5. Either re-power up your board or launch the debugger in your IDE to begin running the example.
