Development and application of TFT HMI display serial port solution part one

As the name suggests, the definition of serial screen is a TFT color LCD display control module with serial communication.

Detailed definition: A set of display solutions consisting of a microcontroller or PLC with a controller. The communication part of the display solution consists of serial communication, UART serial port or SPI serial port, etc.; it consists of three parts: display driver board, casing, and LCD screen. Receive instructions sent from the serial port of the user's microcontroller and complete all operations of drawing on the LCD.

Serial screen products generally consist of two parts: serial screen hardware equipment (slave computer) and serial screen operating software (host computer):

(1) The hardware part includes processor, LCD screen, touch panel, FLASH storage, RS232 or 485 serial port chip, audio and video decoding chip, SD card slot, etc. Some models include WIFI, 4G, Bluetooth, voice recognition, and face recognition. , fingerprint recognition and other modules. The performance of the processor determines the performance of the serial screen product and is the core unit of the serial screen.
