基于DSP点阵液晶显示器的接口与控制

Interface and Control of Dot Matrix LCD Based on DSP

采用TMS320LF2407DSP和1/4VGA液晶显示模块设计了一种便携式检测仪器的显示系统。给出了DSP与液晶显示模块之间的硬件接口设计方案,基于C语言编写了控制程序,解决了DSP与液晶显示模块之间的时序匹配问题。该程序具有较好的移植性,可方便地用于其他由DSP和LCD组成的显示系统中。

The display system for a portable detecting instrument was designed based on TMS320LF2407 DSP and 1/4VGA LCM.The design scheme of the hardware interface between DSP and LCM was presented,and the control software was programmed using C language which resolved the timing match problem between DSP and LCM.With good implementation,the control program can be used easily in other display system consisted by DSP and LCM.
