Hardware requirements

  • Type-C USB cable

  • FRDM-MCXL255 board

  • Personal Computer

Board settings

  • Provide 0-3.3V voltage to J6-1 “AN” pin (ADC ch0 P3_9).

Prepare the Demo

  1. Connect a USB Type-C cable between the host PC and the LPC-Link USB port (J16) 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. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
