  • Personal Computer

Board settings

SPI one board:

  • Transfer data from instance0 to instance 1 of SPI interface, SPI0 pins are connected with SPI1 pins of board

INSTANCE0        CONNECTS TO         INSTANCE1
Pin Name   Board Location     Pin Name  Board Location
MISO       J1 pin 11          MISO      J2 pin 10
MOSI       J1 pin 9           MOSI      J2 pin 8
SCK        J1 pin 15          SCK       J2 pin 12
PCS0       J1 pin 7           PCS0      J2 pin 6

Prepare the Demo

  1. Connect a type-c USB cable between the host PC and the MCU-Link USB port (J13) 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. 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!
