UART (Universal Asynchronous Receiver/Transmitter) is the most common and simplest communication method in the embedded world. Its core idea is: parallel data input → serialized bit stream by frame → the receiver samples and recovers at the same baud rate. It is simple to implement and low in cost, but has limited scalability. This article … Read more
