What is the UART-laser ranging module communication protocol
Dec 09, 2019
UART is a universal serial data bus for asynchronous communication. The bus has two-way communication and can realize full-duplex transmission and reception. In embedded design, UART is used for communication between host and auxiliary equipment, such as communication between car audio and external AP. Communication with PC includes communication with monitoring debugger and other devices, such as EEPROM.
The parallel data transmitted from the computer is converted into an output serial data stream. Serial data from outside the computer is converted into bytes for use by the parallel data device inside the computer. A parity bit is added to the output serial data stream, and a parity check is performed on the data stream received from the outside. Add a start-stop flag to the output data stream and remove the start-stop flag from the received data stream. Handles interrupt signals from the keyboard or mouse (the keyboard and mouse are also serial devices). Can handle the synchronous management of the computer and external serial devices. Some higher-end UARTs also provide buffers for input and output data. The newer UART is 16550. It can store 16 bytes of data in its buffer before the computer needs to process the data. The usual UART is 8250.
interface
The UART can be said to be the most basic configuration in a single-chip computer. Many devices that communicate with computers use it. According to the most conventional description of computers, it is serial communication.
TX-data transmission interface
RX-data receiving interface
Connect TX to RX between the two devices, and connect RX to TX to work normally. The most commonly used is the USB on our computer, which is the most typical UART interface.
The JRT laser range module uses asynchronous serial communication (UART), which can exchange data with the microcontroller and can also be used for secondary development. And the laser distance sensor has superior performance in the field of measurement, fast and accurate measurement,JRT is an expert in the field of laser ranging sensors, welcome your inquiry.
