Overview
|
||
|
|
========
|
||
|
|
The spi_polling_board2board_master example shows how to use spi driver as master to do board to board transfer with
|
||
|
|
polling:
|
||
|
|
|
||
|
|
In this example, one spi instance as master and another spi instance on othereboard as slave. Master sends a piece of
|
||
|
|
data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

Prepare the Demo
|
||
|
|
================
|
||
|
|
1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J7) on the board
|
||
|
|
2. Open a serial terminal with the following settings (See Appendix A in Getting started guide for description how to determine serial port number):
|
||
|
|
- 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 CMSIS DAP terminal like:
|
||
|
|
|
