- Jul 10, 2018 -

The main functions of the tft-lcd module are: decoding of jpeg format images; support for 24-bit color rgb image data and jpeg image display; character display; data storage capacity of 64mbyte, which can realize image library and character library Update; different serial port baud rates can be set. The block diagram of the module is shown in the figure.

Tft-lcd module structure design

The module hardware consists of four parts: arm9s3c2440x processor, data storage module, liquid crystal display module and rs232 serial communication module. Two non-volatile flash nand flash and nor flash are used in the module. Considering that nor flash has on-chip execution and high reliability, it is used to store the program code of the arm9 processor; nand flash with large storage capacity and high cell density is used to store massive data as image library and character library. Storage unit. Sdram is used as an external expansion memory. Tft-lcd lq080v3dg01 is used as the display of the module. Communicate with other external modules using the rs232 serial port.
