1. Introduction UART, full name Universal Asynchronous Receiver/Transmitter, translated as Universal Asynchronous Transceiver. The emergence of serial ports was around 1980, with data transmission rates of 115kbps～ 230kbps. Initially, serial ports were used to connect computer peripherals, typically connecting mice, external Modems, and old cameras and graphics tablets. Serial ports can also be used for … Read more
Reprinted from CSDN: https://blog.csdn.net/an520_/article/details/125479812 UART, SPI, I2C, and other serial communications are very common communication methods in embedded development. The underlying communication principles of these protocols are not difficult, but many beginners struggle to learn them. Today, I will share some common underlying data transmission principles. 1. UART Serial Port UART: Universal Asynchronous Receiver/Transmitter. The … Read more
