SPI (Serial Peripheral Interface) is a full duplex synchronous serial communication interface used for short distance communications. It is usually used for communication between different modules in a same device or PCB. SPI devices communicates each other using a master slave architecture with a single master. SPI Communication SPI is called as a 4-wire bus as it requires four wires for its communication as shown above. In the case of single slave communications we need only 3 wires, as slave select (SS) [...]
