It’s important to understand their differences in order to choose the best protocol for your project. The most common communication protocols that can fulfill these criteria for integrated circuits are the I2C (inter-integrated circuit) protocol and the SPI (serial peripheral interface) protocol. If your embedded systems project involves programming a microcontroller to interface with peripheral devices on a PCB, you will need to choose a wired communication protocol that effectively facilitates internal communication for your device.
Wired protocols can facilitate internal communication (between devices on the same bus), or external communication (between devices on different buses)
#Spi serial communication protocol software
A communication protocol establishes rules that govern the transmission of data and information between separate hardware and/or software systems. Commonly known examples include USB (Types A and B, and the recently released Type-C), Ethernet, and Bluetooth. There are many different types of communication protocols used in computer hardware today. Just like humans can communicate with others using different languages, communication protocols facilitate data transfer between hardware, software, or a combination of the two. Communication protocols define the rules of communication, syntax, semantics, and how the system will recover from errors. A communication protocol is a defined system that allows two or more entities in a communications system to talk to each other.
Communication Protocols in Embedded SystemsĬommunication protocols are central to how we understand and develop embedded systems and devices.
