51单片机读写D1302 包含对时钟区以及RAM区两部分的读写例程，下载直接使用绝无BUG...

51读写cf卡源码 因工程需要存储大量的数据，今天参考参考德国人的一个基于avr的cf控制程序，移植了一个51上面使用的cf驱动程序-Cf card 51 to read and write source code because the project needs a large amount of data storage, today people refer to a reference to Germany avr based on the cf control procedures, transplantation of a 51 top used cf driver

本人设计的用802051实现的键盘程序的识别代码。系统采用定时查询，防抖。如果监测到你一个代码，系统将键盘码输出。然后给我你个中断，用于提示中心机，读取键码。支持长按。-I designed keyboard with 802,051 procedures to achieve the identification code. System uses a regular query, Anti-Shake. If the monitoring to you a code, the system will output the keyboard code. And then give me interrupt you for the prompt Center machine, read the key code. Support the long press.
