Detailed Explanation of the SPI Protocol

Introduction to the SPI Protocol SPI is the Serial Peripheral Interface. It is a synchronous serial interface technology introduced by Motorola, characterized by high speed and full-duplex synchronous communication, capable of operating at frequencies exceeding hundreds of MHz. Typically, SPI requires four lines (for duplex communication), but it can also operate with three lines (for … Read more

Common Communication Protocols in Power Systems: RS-232 as a Country Road, RS-485 as a Highway? A Systematic Discussion of Their Differences!

In the previous article, we discussed the differences between Modbus and RS-485, which belong to different layers. If we use a language analogy, then Modbus determines which “language” to use, while RS-485 and RS-232 determine the method of communication, such as face-to-face or telephone communication. In this article, we will discuss the differences between RS-485 … Read more
