Board settings

SPI one board:

  • Transfer data from MASTER_BOARD to SLAVE_BOARD of SPI interface, SPI0 pins of MASTER_BOARD are connected with SPI0 pins of SLAVE_BOARD

           MASTER_BOARD    CONNECTS TO   SLAVE_BOARD
Pin Name   Board Location                Board Location
MOSI       J2-8                          J2-8
MISO       J2-10                         J2-10
SS         J2-6                          J2-6
CLK        J2-12                         J2-12
GND        J2-14                         J2-14

Prepare the Demo

  1. Connect a USB cable between the host PC and the OpenSDA USB port on the target board.

  2. Open a serial terminal with the following settings:

    • 9600 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 example runs successfully, the following message is displayed in the terminal:
