Hardware requirements

  • Mini/micro USB cable

  • LPCXpresso55S36 board

  • Personal Computer

Board settings

Prepare the Demo

  1. Connect a USB cable between the host PC and the MCU-Link USB port 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.

Running the demo

When the demo runs successfully, the terminal will display similar information like the following:
