The dspi_edma_b2b_transfer example shows how to use DSPI driver in edma way:In this example , we need two boards, one board used as DSPI master and another board used as DSPI slave.The file 'dspi_edma_b2b_transfer_slave.c' includes the DSPI slave code.1. DSPI master send/received data to/from DSPI slave in edma . (DSPI Slave using edma to receive/send the data)

The dspi_half_duplex_edma_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 sendsa piece of data to slave, and receive a piece of data from slave. This example checks if the data received fromslave is correct.Besides, master will transfer in EDMA way.

The dspi_half_duplex_edma_transfer_slave example shows how to receive and transmit data to master board.Notice: The SPI slave of this example uses edma 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 begain 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 dspi_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 in interrupt way.

The dspi_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 begain 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 dspi_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 other board as slave. Master sends apiece 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 in polling way.

The dspi_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 dspi_interrupt example shows how to use DSPI driver in interrupt way:In this example , one dspi instance used as DSPI master and another dspi instance used as DSPI slave in the same board.This example does not use the transactional API in DSPI driver. It's a demonstration that how to use the interrupt in KSDK driver.1. DSPI master send/received data to/from DSPI slave in interrupt . (DSPI Slave using interrupt to receive/send the data)

The dspi_interrupt_b2b example shows how to use DSPI driver in interrupt way:In this example , we need two boards , one board used as DSPI master and another board used as DSPI slave.The file 'dspi_interrupt_b2b_master.c' includes the DSPI master code.This example does not use the transactional API in DSPI driver. It's a demonstration that how to use the interrupt in KSDK driver.1. DSPI master send/received data to/from DSPI slave in interrupt . (DSPI Slave using interrupt to receive/send the data)

The dspi_interrupt_b2b example shows how to use DSPI driver in interrupt way:In this example , we need two boards , one board used as DSPI master and another board used as DSPI slave.The file 'dspi_interrupt_b2b_slave.c' includes the DSPI slave code.This example does not use the transactional API in DSPI driver.
