Prepare the Demo

  1. Connect a mini USB cable between the PC host and the OpenSDA USB port on the board.

  2. Open a serial terminal on PC for OpenSDA 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.
