前言本篇所涉及电路均为北京精电蓬远公司测试板电路,其中8031时钟晶振为10M,以模块MGLS240128T为例,这些程序大多引用精电蓬远公司应用软件包里的程序,以及运用了该公司在WINDOWS平台上提取点阵汉字字模软件、抓图软件等工具软件,程序均已严格经过调试。为了正确使用点阵液晶显示模块,我们首先必须了解模块的供电方式和复位电路。点阵图形液晶显示模块的供电方式 Preface The circuit involved in this chapter are the test board circuit of Beijing Jing Yuan Peng company, of which 8031 ​​crystal oscillator is 10M, with the module MGLS240128T as an example, most of these programs refer to the program in the application package of the Jingdeng Punda farms, and the use of The company in the Windows platform to extract lattice Chinese character software, software such as capture software tools, procedures have been rigorously debugged. In order to properly use the dot matrix LCD module, we must first understand the module power supply and reset circuit. Dot matrix graphics LCD module power supply
