本程序是为51系列单片机开发的16*2型液晶模块驱动程序。该驱动程序包含两个文件，将C文件关联入工程，在调用文件前包含H文件即可。程序提供了简便实用的接口程序，具体使用方法参见文件注释。（本驱动程序在Keil C51开发环境中测试成功，并经过多次实践应用）。-the procedures for the development of single-chip 51 16* 2 LCD driver. This driver contains two files, documents related to C, the call of documents containing H documents. Procedures to provide a simple and practical interface procedures, the use of specific methods, see the Notes document. (Driver in the Keil C51 development environment to test successful, and after several practice application).
