experiment-for-51MCU

毕业设计中等精度频率计8051IP核的C语言代码，功能是计算频率，脉宽，相位。还有控制LCD12864(Graduate design Medium precision frequency meter the 8051IP nuclear C-language code, the function is to calculate the frequency, pulse width, phase. As well as control LCD12864)

通过51看门狗定时器的使用，了解看门狗定时器的功能(Through the use of the watchdog timer 51, ​ ​ the Watchdog Timer function )

说明：  该源码实现51单片机之间符合modbus通信协议的通信(This code can achieve communications between MCS51 by modbus protocol. )

avr单片机通过RS485在线程序升级，编译环境IAR,上位机程序使用VC6.0编写。(AVR microcontroller through the RS485 online upgrade program, the compiler environment IAR, the host computer program written in VC6.0.)

固高运动控制卡GE-400-SG随机光盘(GoogolTech GE-400-SG accompany CD)

温湿度报警系统，基于VB的小程序，和DHT11相关。(Temperature and humidity alarm system, VB-based applets, and DHT11 related.)

这是一个基于THEVENIN的锂电池模型，能够观察到SOC和OCV。(This is a DCDC chopper, and is isolated and can be converted to low-voltage DC high-voltage direct current and voltage controlled to achieve, can be used for battery charging and discharging.)

1、ADO技术 2、用对话框显示图片 3、对话框动态伸展(1, ADO technology 2, with a dialog box is displayed pictures 3, the dialog dynamic extension)

stm32下跑通usb外设，编译环境基于keil(stm32 next run through usb peripherals, based on keil compiler environment)

自动交通控制系统用红、绿、黄三支共两组发光二极管表示交通信号灯，利用单片机模拟有时间显示的定时交通信号灯控制管理。信号灯的变化规律可如下： 1）放行线：绿灯亮放行25秒，黄灯亮警告5秒，然后红灯亮禁止。 2）禁示线：红灯亮禁止30秒，然后绿灯亮放行。 3）当某一方向的红灯亮时，若该方向有车通过，则用扬声器声报警。（撞红灯信号可用3-5V模拟量表示）(Automatic traffic control system using red, green, yellow light-emitting diodes, said a total of three traffic lights, the use of single-chip analog time display on a regular traffic signal control and management. Changes of lights to be as follows: 1) Release Line: green clearance 25 seconds, the yellow light warning for 5 seconds, then the red light is prohibited. 2) ban shows lines: the red light is prohibited for 30 seconds, then the green light to release. 3) When the red light in one direction, if the direction of the car through, the alarm speaker sound. (Hit the red signal available 3-5V analog representation))
