Hardware requirements

  • Micro USB cable

  • Two LPCXpresso55S16 boards

  • Personal Computer

Board settings

Connect SPI master on board to SPI slave on other board

The jumper setting: Default jumpers configuration does not work, you will need to add JP20 and JP21 (JP22 optional for ADC use)

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J1) 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. Reset the SoC and run the project.

Running the demo

When the demo runs successfully, the log would be seen on the CMSIS DAP terminal like:

Master Start...!

Succeed!
