What is a UART Display?
A UART display is a type of display module that communicates with a host device (such as a microcontroller, microprocessor, or computer) using the UART (Universal Asynchronous Receiver/Transmitter) communication protocol. This communication method allows for the transmission and reception of data between the display and the host device using serial communication, which involves sending data one bit at a time over a single data line.
Key Features
Serial Communication:
- Asynchronous: UART does not use a clock signal for synchronization. Instead, it uses start and stop bits to denote the beginning and end of each data packet.
- Two-Wire Interface: Involves two primary lines, TX (transmit) and RX (receive).
Data Transmission:
- Baud Rate: The speed of data transmission is set by the baud rate, which must be the same on both the display and the host device to ensure proper communication.
- Data Frame: Typically consists of a start bit, 8 data bits, an optional parity bit for error checking, and one or more stop bits.

How UART Works
- Asynchronous: UART does not use a clock signal for synchronization. Instead, it uses start and stop bits to indicate the beginning and end of data packets.
- Baud Rate: The speed of data transmission is defined by the baud rate (bits per second).
- Data Frame: Consists of a start bit, data bits (usually 8 bits), an optional parity bit for error checking, and one or more stop bits.
Connecting a Display Using UART
To connect a UART display to a microcontroller, follow these steps:
- Wiring: Connect the TX pin of the microcontroller to the RX pin of the display, and the RX pin of the microcontroller to the TX pin of the display.
- Baud Rate Matching: Ensure that both the microcontroller and the display are set to the same baud rate.
- Communication Protocol: Use appropriate commands and data formats as specified by the display manufacturer.
