| Abstract: | The proposal of controlling LCD based a high speed DSP has been given,TMS320F2812 digital signal processor and SO12864 LCD module are introduced,The interface between LCD module and DSP was provided.Described the method,that software simulating time sequence based on DSP throughout analyzing the time sequence of LCD module,The problem of time sequence non-compatible between a high speed DSP and a low speed LCD module can be solved by software program.Through displaying chinese character on LCD indicate that the system showed good results and achieved a better control of the LCD module SO12864.So it meets the requirements. |
