UART TFT
1.What is UART TFT LCD Module
UART stands for Universal Asynchronous Receiver/Transmitter. It is a simple system device that transmits data between serial and parallel forms in which users are able to control high performance Color TFT displays and create high level Graphic User Interface (GUI) from low-end systems. This function is enabled with smart software exchange data between memorizer port and users to make ZERO CODE for HMI development come true.
2. Advantages behind GUI Intelligent TFT LCD Modules
Some differences between the traditional LCD and UART interface LCD's are:
1) Without code programming for realizing GUI effects, users may read and rewrite the code that is stored in the variable memory by serial ports, which greatly reduces the code amount of users' micro controller, and the touching logics as well as displayed contents are defined by configuration files.
2) Functions such as conversing image format and supporting animation effects and images are equipped. Also an extensive font, icon, and image library available for user selection.
3) With only an SD card containing XRD_SET folder which stored touch config. File, Image Icon file, it can realize interface effects without PC terminal assistant operation.
4) Extreme response speed of refresh time (≤200 ms) to meet users' highly real time requirements; Commands will never overflow from the buffer, so that no necessity for users to judge the condition of serial port.
5) With only three data lines, the MCU is capable of controlling the LCD module. Anyone can perform TFT design with minimal programming.
