基于FPGA的LCD液晶动态显示驱动程序的设计

摘要

为了提高工业生产过程中不同参数的可读性及显示的实时性，提出一种采用FPGA器件来实现LCD液晶动态显示的控制方法。在整个设计过程中，完成了显示系统的硬件设计，同时也实现了液晶动态显示驱动程序的设计。驱动程序主要包括A/D转换控制模块和LCD动态显示输出控制模块，利用Quartus II软件内嵌的SignalTap II Logic Analyzer逻辑分析模块对液晶动态显示驱动程序进行了实时测试，结果比较准确；同时也对现场的模拟电压值进行了实际硬件系统的测试，并通过LCD1602读取到了较为准确的电压数据，因此该动态显示系统的设计具有一定的应用价值。%In order to improve the readability and real-time display of different parameters in the industrial process,propose a method of control ing dynamic display of LCD implemented by FPGA devices. Throughout the design process,completed the hardware design of display system,while achieving the de-sign of lcd dynamic display driver.The driver includes the control module of A/D converter and the output control module of LCD dynamic display,using the logic analyzer module of SignalTap II Logic Analyzer embedded in Quartus II software for real-time test to lcd dynamic driver,the result is more accurate;But also the analog voltage value of scene is tested on the hardware system,and read more accurate voltage data from the LCD1602,so the design of dynamic display system has a certain value.
