==============
Populate jumper JP6.
Connect SPI5 pins to SPI3 pins:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Master - SPI5 CONNECTS TO Slave - SPI3
Pin Name Board Location Pin Name Board Location
MISO J1 pin 11 MISO J4 pin 3
MOSI J1 pin 13 MOSI J4 pin 2
SCK J2 pin 8 SCK J4 pin 4
PCS2 J1 pin 15 PCS2 J4 pin 7

FreeRTOS SPI example start.
This example use one SPI instance as master and another as slave on one board.
Master and slave are both use interrupt way.
Please make sure you make the correct郌reeRTOS SPI example start.
This example use one SPI instance as master and another as slave on one board.
Master and slave are both use interrupt way.
Please make sure you make the correct line connection. Basically, the connection is:
SPI_master -- SPI_slave
SCK -- SCK
PCS2 -- PCS2
MISO -- MISO
MOSI -- MOSI
