Board settings

Connect SPI master on board to SPI slave on other board.

    Master_board(SPI1)           Slave_board(SPI1)
Pin Name   Board Location     Pin Name   Board Location
MISO       J1 pin 4           MISO       J1 pin 4
MOSI       J1 pin 2           MOSI       J1 pin 2
SCK        J2 pin 12          SCK        J2 pin 12

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the MCU-Link USB port (J10) 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. Launch the debugger in your IDE to begin running the demo.

Running the demo

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

SPI CMSIS driver board to board dma example.
This example use one board as master and another as slave.
Master and slave uses DMA way. Slave should start first. 
Please make sure you make the correct line connection. Basically, the connection is: 
SPI_master -- SPI_slave   
   CLK      --    CLK  
   PCS      --    PCS 
   MOSI     --    MOSI 
   MISO     --    MISO 
   GND      --    GND 

 Master transmit:

  0  1  2  3  4  5  6  7  8  9  A  B  C  D  E  F
 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F
 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F
 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F
 
SPI transfer all data matched!
