开发环境ICC AVR单片机 用ADC做电压表 (多通道)

电子密码锁程序，两键输入，其中一个键累加，另一个键确认。密码正确锁打开（开锁指示灯亮）；密码错误锁关闭（关锁指示灯亮）；连续错三次则锁定键盘8秒并发出报警声。-Electronic code lock procedure, the two key input, one key additive, and the other button to confirm. The correct password to open lock (unlock indicator light) password error lock closure (Kuan-lock indicator light) consecutive wrong then lock the keyboard three times and issued eight seconds alarm sound.

用8个数码管，用一片48和一片138控制 的子程序，-with eight digital control with a 48 and a control subroutine 138,

本代码为51单片机C语言应用开发技术大全的完整代码 包含51单片机各个模块的代码设计 可直接用于项目开发-The code for 51 MCU application development technology, C-code contains the full corpus of 51 microcontroller code design of each module can be directly used for project development

基于Freescale公司的8位单片机MC68HC908GP32，提供一些简单的实验仿真程序，以便初学者学习-Based on Freescale

自己写的C51仿真器代码-himself wrote the code C51 Emulator

还不错的LCD点阵提取程序,提供一些基本图案.-Dot matrix LCD is also good extraction procedures, to provide some basic patterns.

单片机控制步进电机启动停止，正反转以及转速。proteus+keil.(由于大小不够，还加入了RS485在单片机多机通信中的应用，用到RS485接口芯片max487)-keil+proteus+motorstepper

超级单片机开发软件组合,希望对单片机初学都有用-Super single-chip software portfolio, and they hope to have a single-chip learning with
