为了适应工业化现场应用和仪器仪表测试系统的终端显示需要,提出运用DSPTMS320LF2407A控制液晶显示模块的接口设计方案,详细介绍了DSP和液晶屏控制器的硬件连接和软件设计,软件程序采用C语言编写,具有较强的可移植性.在系统中成功实现了坐标系、文本、图形和菜单的显示.
In order to meet the requirements of industrial application site and terminal display of test system,this paper put forward one method, which uses DSPTMS320LF2407A con-trolled seven-inch liquid crystal display produced by Hitachi. The hardware interface circuit and the software drivers procedures of the method are introduced in detail. Software program is composed of C language, which has strong portability. It achieves the function of displaying coordinate system, text, graph and menu successfully.
