Design of LED Display-Screen System Base on TMS320F2812

LED Display-Screen is widely used as one of display Terminals to reveal the information in all aspects. With the improvement of living standards, people demand LED display screen to work with the high quality, high speed and high intelligence. The paper presents a method to design LED display-Screen with TMS320F2812 DSP chip of TI, Meanwhile it uses GPRS to communicate with the telephone and the information platform for convenient remote control, it can constitute a large LED display with the CAN bus and so on. The test shows that the system is reasonable, realizable, operated easily, flexible, adaptable to environment, low price, and it is useful in practice after being proved in the practical system.
