Key Facts About SPI
- 1SPI uses a master-slave architecture with up to 4 communication lines: SCLK (serial clock), MOSI (master out, slave in), MISO (master in, slave out), and SS (slave select).
- 2SPI supports full-duplex communication, allowing simultaneous data transfer in both directions at baud rates up to 10 Mbps.
- 3SPI peripherals include ADCs, DACs, shift registers, real-time clocks, and EEPROM/flash memory chips commonly found in embedded systems.
- 4The SPI protocol is synchronous, with the master providing a clock signal to coordinate data transmission with connected slave devices.
- 5SPI is widely used in applications like motor control, sensor arrays, display panels, and industrial automation where high-speed, low-latency communication is critical.
