摘要
提出了一种基于DSP控制的液晶显示屏的设计方案。以LM5Q32为例,介绍了TMS320F240对该液晶屏进行控制的硬件接口电路以及软件编写流程,并给出了相应程序。重点说明了彩色液晶控制器QPYD-03的使用方法及其与DSP的接口。系统取得了良好的显示效果,为各种便携式系统显示前端的设计提供了一种借鉴的方法。
Put forward a design proposal for the LCD control based on DSP. Took LM5Q32 as example, introduced the hardware interface and the flowchart of software for its control using TMS320F240, gave the relevant program. Emphasized the using method and interface with the chromatic LCD controlling element QPYD - 03. It got nice displaying effect, and gave a referential method for kinds of portable system＇s front-end display.
