- Basics of SPI: Serial Communications - Texas Instruments
There are two control lines for SPI The controller, usually a microcontroller or DSP, controls a peripheral select and the serial clock used for data synchronization An SPI bus can control multiple peripherals
- SPI Interface Explained: Simple Guide for Beginners
Serial Peripheral Interface (SPI) is a master – slave type protocol that provides a simple and low cost interface between a microcontroller and its peripherals
- Introduction to SPI Interface | Analog Devices
Serial peripheral interface (SPI) is one of the most widely used interfaces between microcontroller and peripheral ICs such as sensors, ADCs, DACs, shift registers, SRAM, and others
- Basics of the SPI Communication Protocol
SPI is a communication protocol used to interface a variety of sensors and modules to microcontrollers This easy to understand guide will explain how it works
- SPI I2C Controllers - ChipVerify
Why Learn SPI and I2C Controllers? SPI and I2C are the workhorses of embedded communication—connecting sensors, flash memory, displays, and peripherals in everything from smartphones to automotive systems Understanding how to design these controllers at the RTL level gives you the skills to create custom communication engines optimized for your SoC's specific needs

SPI works in a slightly different manner It's a "synchronous" data bus, which means that it uses separate lines for data and a "clock" that keeps both sides in perfect sync The clock is an oscillating signal that tells the receiver exactly when to sample the bits on the data line
