摘要
分析了TFT-LCD与PXA270内嵌的LCD控制器的基本原理与时序,根据它们的特点与时序要求,设计了TFT-LCD的硬件驱动接口电路,基于Linux-2.4.19内核设计了相应的驱动程序,软硬件在目标板上工作良好。该设计对于驱动TFT-LCD具有通用性,由于Linux驱动程序移植性强,因而该设计可适用于工业控制领域多种嵌入式系统。
The basic principle and timing sequence of TFT-LCD and embedded LCD-controller of PXA270 are analyzed. According to their characteristics and the request of timing sequence,the hardware drive interface circuit of TFT-LCD is designed.The relevant drive software is also designed based on Linux-2.4.19 kernel. As the result, the hardware and software work well on the target board.The design can be used in most of the embedded device for driving TFT-LCD. Because the Linux display drive software can be well transplanted,so the design can be used in many sorts of embedded system in the industry control areas.
