The spi_half_duplex_int_transfer_master example shows how to use driver API to transfer in half-duplex way. In this example, one spi instance as master and another spi instance on the other board 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.Besides, master will transfer data in interrupt way.

The spi_half_duplex_int_transfer_slave example shows how to receive and transmit data to master board.Notice: The SPI slave of this example uses interrupt mode. The data transfer size(not buffer size) is twice ofthe master's transfer size. The first half of the transmission will receive data, and the second half will senddata back to master, so the address of the receive buffer is &rxDataPolling[64].In this example, one spi instance as slave and another spi instance on the other board as master. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from master is correct. And slave will print what it received.

The spi_half_duplex_polling_transfer_master example shows how to use driver API to transfer in half-duplex way. In this example, one spi instance as master and another spi instance on the othere board 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.Besides, master will transfer data in polling way.

The spi_half_duplex_polling_transfer_slave example shows how to receive and transmit data to master board.Notice: The SPI slave of this example uses interrupt mode. The data transfer size(not buffer size) is twice ofthe master's transfer size. The first half of the transmission will receive data, and the second half will senddata back to master, so the address of the receive buffer is &rxDataPolling[64].In this example, one spi instance as slave and another spi instance on the other board as master. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from master is correct. And slave will print what it received.

The spi_interrupt example shows how to use spi functional API to do interrupt transfer:In this example, one spi instance as master and another spi instance as slave. Master sends a piece of data to slave,and check if the data slave received is correct.

The spi_interrupt_b2b_master example shows how to use spi functional API to do interrupt transfer as a master:In this example, the spi instance as master. Master sends a piece of data to slave, receive data from slave,and checkif the data master received is correct. This example needs to work with spi_interrupt_b2b_slave example.

The spi_interrupt_b2b_slave example shows how to use spi functional API to do interrupt transfer as a slave:In this example, the spi instance as slave. Slave receives data froma master and send a peiece of data to master,and check if the data slave received is correct. This example needs to work with spi_interrupt_b2b_master example.

The spi_interrupt_board2board_master example shows how to use spi driver as master to do board to board transfer withinterrupt:In this example, one spi instance as master and another spi instance on othereboard as slave. Master sends a piece ofdata to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

The spi_interrupt_board2board_slave example shows how to use spi driver as slave to do board to board transfer with interrupt:In this example, one spi instance as slave and another spi instance on other board as master. Master sends a piece ofdata to slave, and receive a piece of data from slave. This example checks if the data received from master is correct.

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 ofdata to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.
