SFCW

说明：  2015年电赛国测题，频率测量。基于stm32的频率测量。优点：精密度高，代码简单(In 2015, the National Test of Electricity Competition, Frequency Measurement. Frequency measurement based on stm32. Advantages: High precision, simple code)

用数码管显示电压，发送到串口，然后有高低电压报警，只有部分代码(Display voltage with digital tube, send it to serial port, then alarm with high and low voltage, only part of the code)

msp430g2553利用定时器产生多路可调占空比PWM(Make PWM by MSP430G2553.)

microcontroller programing

lcd_show c51程序，显示部分C语言程序(lcd_show decoder procedures, as some C language program)

CAN test测试功能软件,帮助快速开发产品(CAN test测试功能软件)

说明：  18B20数字温度计，驱动液晶显示的，可以实现报警功能(18B20 digital thermometer, to drive liquid crystal display, alarm function can be achieved)

基于STC89C51的红外解码程序，并且在数码管显示(STC89C51 based infrared decoding procedures, and in the digital display)

单片机的40个实验，这个很全的，是一个很好的东西，希望大家好好使用它。(SCM 40 experiment, this is very full, is a very good thing, hope everyone to use it. )

测试步进电机正反转，可以看到步进电机正转一会儿又反正，一直循环。(Test step motor and reversing, can see is a stepping motor and anyway, have been circulating.)
