WebThe Serial Peripheral Interface ( SPI) is a synchronous serial communication interface specification used for short-distance communication, primarily in embedded systems. The interface was developed by Motorola in the mid-1980s and has become a de facto standard. Typical applications include Secure Digital cards and liquid crystal displays . WebFor convenience, the chip select mode can be set to automatic by clearing bit 1 in the CR; If auto-CS is enabled, the chip select will only drive when an SPI transaction is active. Before you start a transaction, set the CS field in the control register (bits 13:10) to the appropriate value for the slave device you want.
