Hardware requirements

  • Mini/micro USB cable

  • LPCXpresso54S018 board

  • Personal Computer

Board settings

Remove jumper for JP4, connect the external input voltage to JP4_6.

Prepare the Demo

Note: MCUXpresso IDE project default debug console is semihost

  1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (P6) on the board

  2. Open a serial terminal with the following settings (See Appendix A in Getting started guide for description how to determine serial port number):

    • 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

The log below shows the output of the BOD demo in the terminal window:

BOD INTERRUPT EXAMPLE.
Please adjust input voltage low than 2.86V to trigger BOD interrupt.

BOD interrupt occurred, input voltage is low than 2.86V.
