用于51系列的单片机开发时基本的7段数码管驱动源代码-51 Series Microcontroller for the development of basic paragraph 7, when the digital control-driven source code

本人at89c51snd1c主控IC增加了128*32点阵驱动显示，帮助MP3DIY者学习用-I at89c51snd1c control IC increased by 128* 32 dot matrix display drive to help those who learn MP3DIY

使用AVR单片机控制的温控与定时,时间从0至99小时99分99秒,温度从-55度到99度.-AVR single-chip microcomputer to control the use of temperature control and timing, the time from 0-99 hours 99 minutes 99 seconds, temperature from-55 degrees to 99 degrees.

义隆单片机控制8个LED的渐明渐暗，并有一个按键控制流水灯的速度！-Elan single-chip control of the eight LED dimming out gradually, and there is a button to control the speed of light water!

鉴于MCS-51系统只提供“二级中断嵌套”，提出扩展51系统中断优先级的纯软件方法。其利用51系统内建的中断允许寄存器IE和中断优先级寄存器IP，通过屏蔽字机制来实现；以C51的形式，给出这种扩展方法的函数库实现，为该方法的使用赋予友好、简洁的用户接口。-Given MCS-51 systems only provide "two interrupt nesting," expanded 51 priority system interruption of pure software. The use of 51 built-in system allows interruption Register IE and priority interrupt register IP, through word shielding mechanisms to achieve; C51 in the form of this expansion is the way to achieve functions, methods for the use of empowerment friendly, simple user interface.

我测试通过的液晶驱动汇编程序,适用于所有不带字库的液晶,如CA12864A-I tested the LCD driver compilation procedures, applicable to all non-character LCD, as CA12864A

SD卡读写程序 1. sdconfig.h: 该文件为SD卡读写模块配置头文件，用户可根据实际硬件条件进行修改. 2. SD目录: SD卡读写模块的全部文件,一般不用修改. 3. 建议sdconfig.h文件不要放于SD目录中，因为SD目录中的文件一般无须修改, 而sdconfig.h通常会有改动.-1. Sdconfig.h: The document for the SD card reader module configuration header files, the user hardware according to actual conditions can be modified. 2. SD directory: SD card reader module of all the documents, the general need not be amended. 3. Proposed sdconfig. h files directory should not be put in SD because SD files in the directory are not normally required to be amended and the changes are usually sdconfig.h.
