WebIntroduction Serial Peripheral Interface (SPI) is an interface bus commonly used to send data between microcontrollers and small peripherals such as shift registers, sensors, and SD cards. It uses separate clock and data … 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. Usually chip select is an active low signal; hence, the main must send a logic 0 on this signal to select the subnode. … See more In SPI, the main can select the clock polarity and clock phase. The CPOL bit sets the polarity of the clock signal during the idle state. The idle state is defined as the period when CS is high and transitioning to low at … See more Multiple subnodes can be used with a single SPI main. The subnodes can be connected in regular mode or daisy-chain mode.
