SPI Protocol
makerSPI (Serial Peripheral Interface) Protocol is a synchronous serial communication protocol used primarily for short-distance communication.
expanded
SPI Protocol facilitates full-duplex communication among devices and is commonly used to interface microcontrollers with peripheral devices such as sensors, memory, and displays. It operates over four wires: MOSI, MISO, SCLK, and SS, allowing for multiple slave devices through common master-slave architecture. It is valued for its simplicity and speed, with typical data rates up to 10 Mbps, depending on the system implementation.
examples
A microcontroller such as the Arduino UNO R3 using SPI to communicate with an ADC (Analog to Digital Converter) like the MCP3008.
Arduino projects often utilize SPI for interfacing with an ADC to read multiple analog inputs where speed is crucial.
An SPI interface used between a Raspberry Pi 4 and an SPI-compatible OLED display.
In embedded systems projects, Raspberry Pi is frequently used to send data to displays like OLEDs via SPI due to the ease of multiple screen updates.
