COMUNICACIONES - ¿Cómo funcionan? - Parte 4 - El protocolo SPI

Welcome to the fourth video in our series on microcontroller communication, where we'll analyze the SPI protocol. SPI stands for Serial Peripheral Interface, and it's widely used for communication between microcontrollers and peripherals, such as sensors, flash memory, or SD card readers. The SPI protocol is quite similar to I2C in that it's synchronous; that is, it has a clock signal that tells the sender when to send the next bit and the receiver when to read it. If you recall the UART video, this isn't the case in an asynchronous system, and we had to develop a series of protocols to keep the sender and receiver synchronized.
