| Abstract: | The embedded microprocessor PXA255 and its integrated LCD controller are introduced,the basic principle of TFTLCD is also analyzed.Combining with their characteristics and the timing sequence,the hardware drive interface circuits are designed,then making Linux as embedded operation system,the correspond drive software is designed.As the result,the clear and stable pictures can be shown on the LCD.Because the software can be well transplanted,the display drive can be used in not only the building automation system,but also the other embedded systems with a few changes. |
