UART

UART Frame Format UART (Universal Asynchronous Receiver/Transmitter) sends data in a structured frame that includes the following components: Start Bit: Always 0; indicates the beginning of the frame. Data Bits: The actual payload, typically 5 to 8 bits. Parity Bit (optional): Used for simple error detection. Stop Bit(s): One or two bits set to 1; mark the end of the frame. Parity Bit Modes Even Parity: The parity bit is set such that the total number of 1s (including the parity bit) is even. ...

Overview What is UART? UART (Universal Asynchronous Receiver/Transmitter) is a hardware communication protocol used for serial communication between two devices. It is called asynchronous because it does not require a separate clock signal like SPI or I2C. Instead, both devices agree on a common data rate (baud rate) to ensure correct data transmission. How Does UART Work? UART consists of two main data lines: TX (Transmitter) Line – Sends data. ...
