WebOct 5, 2015 · The Raspberry Pi 2 provides two CS pins that will allow you (typically) to connect just two devices to the SPI bus. The CS pins are physical pin numbers 24 and 26. This is defined by the hardware. Hope that helps. WebSPI is a synchronous serial communication protocol used to communicate between devices. SPI uses a master-slave architecture, with a single master device initiating the communication frame, and operates in full-duplex mode (data is sent and received at the same time). In digital systems, data is transferred in the form of 1’s and 0’s.
