This SCTIMer project is a demonstration program of the SDK SCTimer driver's PWM generation. It sets up a PWM signaland periodically updates the PWM signals dutycycle.

The SCTimer project is a simple demonstration program of the SDK SCTimer's driver capabiltiy to generate PWM signals.

The Shell Demo application demonstrates to control Leds by commands.

The spi_dma_b2b_transfer_master example shows how to use driver API to transfer in DMA 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 checksif the data received from slave is correct. This example needs to work with spi_dma_b2b_transfer_slave example.Note: This example will run in master mode, please prepare another board for slave, and the slave board should be started first.Project Information1.How to set the baudrate of SPI? The baudrate of SPI is easy to set, just make sure the source clock of SPI.

The spi_dma_b2b_transfer_slave example shows how to use driver API to transfer in DMA 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 checksif the data received from master is correct. This example needs to work with spi_dma_b2b_transfer_master example.

The spi_half_duplex_dma_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 DMA way.

The spi_half_duplex_dma transfer_slave example shows how to receive and transmit data to master board.Notice: The SPI slave of this example uses dma 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_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.
