Board settings

SPI one board: Transfer data from instance0 to instance 1 of SPI interface. SPI9 pins are connected with SPI2 pins of board

INSTANCE0(SPI9)     CONNECTS TO         INSTANCE1(SPI2)
Pin Name   Board Location     Pin Name  Board Location
MISO       J9 pin 11          MISO      J13  pin 12
MOSI       J9 pin 13          MOSI      J13  pin 2
PCS0       J9 pin 15          PCS0      J9   pin 3
SCK        J9 pin 9           SCK       JP11 pin 2

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the LPC-Link USB port (J8) 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:

SPI one board interrupt example started!

SPI transfer finished!
