89c52的串口通信的演示 (89c52 serial communication demonstration)

这是一款模拟modbus从机的程序，可以方便用户调试modbus程序，本程序完全免费。(This is a simulation of the modbus from machines, can facilitate users to debug the modbus program, this program is completely free. )

基于51单片机实现定位，并通过sim900a把定位信息发送到指定手机(base on 51 chip,send location to phone)

STM32L152VB的AD采集程序，7通道DMA方式采集，通过串口发送到PC，本人查阅多方资料亲自编程测试，可直接用。附带STM32L152VB工程模板，本人根据资料自己建的。(The AD STM32L152VB acquisition program, 7 channel DMA acquisition, through the serial port to send to the PC multi access information, I personally programming test, can be directly used. With STM32L152VB project templates according to the data, I built myself. )

可实验0.5KHZ到10KHZ的简单测频,并由数码管显示出来!(Experimental 0.5KHZ can be simple to 10KHz frequency measurement by digital tube display!)

说明：  c8051f020图片显示 不复杂 可以自己变换图片 第一次写这类的 不太好大家指出(the c8051f020 picture display pictures online to find the program)

电子密码锁设计，实现四位密码开锁，可改密码(Electronic password lock design to achieve four bit password lock, password can be changed)

Thread Templete Class Custom Thread

对STM8L151各个功能模块测试程序,十分方便初学STM8L151各个功能有IO中断,中断唤醒,定时中断,串口接收发送,AD转换程序,SLEEP模式(STM8L151 each function module test program, very convenient beginners STM8L151 each function is IO interruption, interrupt, timer interrupt, serial port receive send, AD converter, the SLEEP mode)

本程序实现基于单片机的自动电阻测试，包括AD芯片的使用和继电器的控制。(This procedure to achieve automatic resistance measurement based on single chip microcomputer, control and relay includes a AD chip.)
