This example is based on the GD32F307C - EVAL - V1.1 board, it shows SPI0 and SPI1 simuplex
communication using DMA mode.

1.Master tramsmit slave receive mode:
Connect SPI0 SCK PIN(PA5) TO SPI1 SCK PIN(PB13).
Connect SPI0 MOSI PIN(PA7) TO SPI1 MOSI PIN(PB15).
Connect SPI0 NSS PIN(PA4) TO SPI1 NSS PIN(PB12).

Modify file:
examlple / SPI / SPI_master_slave_simplex_dma / main.c, choose master tramsmit slave
receive mode.
#define MASTER_TRAMSMIT_SLVAE_RECEIVE
//#define SLVAE_TRAMSMIT_MASTER_RECEIVE

After the communication is completed, if the data received is equal to the data sent, LED2
turn on, if not LED2 turn off.

2.Slave tramsmit master receive mode:
Connect SPI0 SCK PIN(PA5) TO SPI1 SCK PIN(PB13).
Connect SPI0 MISO PIN(PA6) TO SPI1 MISO PIN(PB14).
Connect SPI0 NSS PIN(PA4) TO SPI1 NSS PIN(PB12).

Modify file:
examlple / SPI / SPI_master_slave_simplex_dma / main.c, choose slave tramsmit master
receive mode.
//#define MASTER_TRAMSMIT_SLVAE_RECEIVE
#define SLVAE_TRAMSMIT_MASTER_RECEIVE

After the communication is completed, if the data received is equal to the data sent, LED3
turn on, and if not, LED3 turn off.
