WebJun 1, 2024 · SPI over long distance. Raspberry PI's SPI over RS485. It seems that it's a common practice to use RS-485 transceivers to transmit SPI over long distance. If I understand it correctly, you are not exactly creating a star topology, but rather multiple point-to-point connections. 4-wire SPI devices have four signals: 1. Clock (SPI CLK, SCLK) 2. Chip select (CS) 3. main out, subnode in (MOSI) 4. main in, subnode out (MISO) The device that generates the clock signal is called the main. Data transmitted between the main and the subnode is synchronized to the clock generated by the main. … See more To begin SPI communication, the main must send the clock signal and select the subnode by enabling the CS signal.
