Communication Protocols

What is SPI protocol? | Explained

What is SPI protocol? Serial peripheral interface protocol is a kind of serial communication protocol that follows the full-duplex communication process for transmitting data. It is a synchronous protocol; whose transmission speed is high. The SPI protocol is also considered a master-slave type protocol because it is very simple and a perfect one for interfacing between microcontrollers and their peripherals. The main purpose of using SPI protocol is two interacting with microprocessor and microcontroller with some memories, like – PROM, EPROM, ADC (analog to digital converter), DAC (digital to analog converter), RTC (Real-time clock), several sensors, memory cards and with other types of microcontrollers.

What is I2C protocol? | Explained

I2C is a type of serial communication protocol, through which the data is sent bit by bit, with the help of a single wire. The full form of I2C is an inter-integrated circuit or inter IC. This 8-bit serial communication protocol takes the assistance of bus wires, which is: serial data wire (SDA) and serial clock wire (SCL) sending data. I2C is the combination of different types of ICs and it helps the devices for interacting directly with each other through sending data.
