Spi master with multiple slaves
WebMar 16, 2024 · An SPI 3-wire communication scheme is a half-duplex data link. The master initiates the transaction by pulling the Slave Select (SS) wire low. A Serial Clock (SCLK) line, driven by the master, provides a synchronous clock source. The Serial Data In/Out line is a bidirectional data line over which the master transmits and receives data. WebSep 8, 2024 · SPI is a master-slave type interface. There can be only one master of an SPI bus; however, the number of slaves can be one or more. Though, it is possible to have multi-master protocol over SPI, it gets cumbersome, and multi-master SPI communication is possible with only a single slave. ...

It consists of a serial clock, master output/slave input, master input/slave output, and a device select pin. The speed of the bus range is much higher than that found in I2C or SMBus; speeds up to 80 MHz are not uncommon.
