UART Example
UART (Universal Asynchronous Receiver/Transmitter) is a commonly used serial communication peripheral that can complete data exchange with only two data lines, where TX (transmitter) is used for sending, and RX (receiver) is used for receiving. UART uses asynchronous transmission, eliminating the need for an additional clock line and relying on a consistent baud rate to achieve data synchronization. Its structure is simple and widely used, often used for sensor connections, debugging interfaces, and wireless modules, etc., helping the system to achieve efficient data interaction with external devices.
For basic knowledge about UART peripherals and related API introductions, please refer to Universal Asynchronous Receiver/Transmitter (UART). This document explains the general configuration process and specific implementation methods through the UART peripheral examples provided by the official ESP-IDF, helping to learn and master the use of UART peripherals.
