SPI Protocol
Serial Peripheral Interface (SPI) is a synchronous serial communication protocol widely used for short-distance communication between microcontrollers and peripheral devices. Developed by Motorola, SPI has become one of the most popular protocols in embedded systems due to its simplicity, high-speed capability, and full-duplex communication.
SPI uses a master-slave architecture with four main signals: Serial Clock (SCLK), Master Out Slave In (MOSI), Master In Slave Out (MISO), and Chip Select (CS). The protocol supports multiple slave devices through individual chip select lines, making it ideal for connecting sensors, memory devices, displays, and other peripherals that require high-speed data transfer.
Our USB host adapters provide comprehensive SPI support, enabling you to communicate with SPI devices, configure SPI parameters, and develop firmware for SPI-based systems. With support for all four SPI modes (0, 1, 2, 3) and configurable clock speeds, our tools give you the flexibility to work with a wide range of SPI devices.
