Reachability

单片机C语言入门教程，非常适合新手入门。从基础讲起，逐步提高。(Single-chip C Language Tutorial, very suitable for beginners. Start from the base, and gradually improve.)

说明：  电动车控制器 DC负安培高刹车防盗三速提速20带霍尔显示(Electric Vehicle Controllers )

基于51单片机的信号发生器 四种波形显示 有级调频(Based on 51 single-chip signal generator)

iOS 网络状态监测。网络实时检测，用到Reachability（自行下载）,需加框架:SystemConfiguration.framework ios程序需要用到网络检测，有些程序是刚启动时检测一次，而有些则从头到尾检测网络状态。(IOS network status monitoring.Real-time detection and Reachability (download), frame: SystemConfiguration.framework IOS programs need to use network detection, some detection once when the program is launched, while others detect the network status start to finish.)

Code written in MPLAB for I2C with PIC18f45k80

IOS端通过蓝牙发送和接收 用的是OC语言，在MACOS上编程(bluetooth sent data and bluetooth received data for IOS)

单片机AD功能实例，使用1602显示电压(SCM AD function example, the use of 1602 shows the voltage)
