Serial screen manufacturers introduce you to the serial screen
Edit:Shenzhen Koroli Electronic Technology Co., Ltd.   UpDate:2019-11-07

Founded in 2014, Shenzhen Koroli Electronic Technology Co., Ltd. is a semiconductor agent and display solution provider; Koroli has been focusing on industrial control, liquid crystal display module, serial port, and is a semiconductor distribution, application and development. A diversified enterprise.

The serial port screen is composed of three parts: display driver board, outer casing and LCD liquid crystal display; a set of display schemes by single-chip microcomputer or PLC with controller, the communication part in the display scheme is serial communication, USART serial port or SPI serial port;

Microcontrollers (Microcontrollers) is an integrated circuit chip that uses a very large-scale integrated circuit technology to have a central processing unit CPU with data processing capability, random access memory RAM, read-only memory ROM, various I/O ports and interrupt systems, and timers. Functions such as a counter/counter (which may also include display driver circuits, pulse width modulation circuits, analog multiplexers, A/D converters, etc.) integrated into a small piece of silicon to form a small and complete microcomputer system in the industry The control field is widely used. From the 1980s, from the then 4-bit, 8-bit microcontroller, to the current 300M high-speed microcontroller.

The USART is a full-duplex universal synchronous/asynchronous serial transceiver module that is a particularly flexible serial communication device. Contains three major clock generators, data transmitters and receivers. Control registers are shared by all modules.

The SPI (Serial Peripheral Interface) bus system is a synchronous serial peripheral interface that allows the MCU to communicate with various peripheral devices in a serial manner to exchange information. The SPI bus can be directly connected to a variety of standard peripheral devices from various manufacturers, including FLASHRAM, network controllers, LCD display drivers, A/D converters and MCUs. The interface typically uses four lines: a serial clock line (SCLK), a master input/slave output data line MISO, a master output/slave input data line MOSI, and an active low slave select line NSS.
