Board settings

This example project does not call for any special hardware configurations. Although not required, the recommendation is to leave the development board’s jumper settings and configurations in default state when running this example.

Prepare the Demo

1. Connect a type-c USB cable between the host PC and the MCU-Link USB port (J13) on the target board.

2. Open a serial terminal 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.
