Click the blue text above to follow us 1. What is I2C? I2C, short for Inter Integrated Circuit, is a two-wire serial bus developed by Philips for communication between SOCs and peripherals. It requires only two wires for communication, operating in a master-slave mode where the master can read and write data, while the slave … Read more
In embedded development, interfaces such as UART, I2C, and RS485 are commonly used. Understanding them may be ambiguous, so this article organizes them. The article is lengthy, with an estimated reading time of about 10 minutes. UART (Universal Asynchronous Receiver-Transmitter) The UART port refers to a type of physical interface (hardware). UART is an asynchronous, … Read more
