Running the demo
When the example runs successfully, you can see the similar information on the terminal as below.
DSPI interrupt example start. This example use one dspi instance as master and another as slave on one board. Please make sure you make the correct line connection. Basically, the connection is: DSPI_master – DSPI_slave CLK – CLK PCS – PCS SOUT – SIN SIN – SOUT DSPI master transfer completed successfully.
DSPI slave transfer completed successfully.
DSPI transfer all data matched!
