Hardware requirements

  • Micro USB cable

  • Two LPCXpresso55S16 boards

  • Personal Computer

Board settings

SPI one board: Transfer data from SPI slave interface on board to other SPI interface 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 LPC-Link USB port (J1) on the 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.  Reset the SoC and run the project.

Running the demo
===============
When the demo runs successfully, the log would be seen on the terminal like:

​~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Slave is working....

Succeed!
