The SDCARD Polling project is a demonstration program that uses the SDK software. It reads/writes/erases the SD card continusly. The purpose of this example is to show how to use SDCARD driver andshow how to use polling based transfer API in SDHC driver in SDK software to access SD card.Note: If DATA3 is used as the card detect PIN, please make sure DATA3 is pull down, no matter internal or external, at the same time, make sure the card can pull DATA3 up, then host can detect card through DATA3.And SDHC do not support detect card through CD by host, card can be detected through DATA3 or GPIO.No matter detect card through host or gpio, make sure the pinmux configuration is correct.

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...See more details in readme document.

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.
