How to Use the SAMA5D2 SPI Under Linux®

PublishTime：2021-10-25

This application note describes how to get started using the SAMA5D2 SPI under Linux.
Since the SPI dev interface was introduced into the kernel, it is easy to access the SPI device in user space via the device node “/dev/spidev”. Refer to the section Application for SPI dev application demo code.
SPI devices have a limited user space API, supporting basic half-duplex read() and write() access to SPI slave devices. Also available are ioctl() requests, full duplex transfers and device I/O configuration.
