Abstract: S3C2440A is a 16/32-bit RISC microprocessor and has a strong ability to control and signal processing. The paper introduced the development and application of the LQ084V3DG01 LCD module based on S3C2440A. According to the interface timing and logic requirements of LCD, it designed the interface circuit to S3C2440A. It also completed the setting of LCD parameter, cha-racters, clear screen and image display. The program can be well transplanted and applied to dif-ferent pixel formats of LCD system. C language is adopted to carry out software design, which makes the program transplantable. Project application results show that the system is stable, has good effects and has better use value in the project.
