基于430g2233的温度程序，有18B20和PT1000，两种传感器(The temperature program based on 430g2233)

AT89S52键盘程序,这是一个变频器的键盘驱动程序，简单，可靠，芯片为51单片机(one simple progrem for 51,if you like ,you can use it freely.)

MSP430上类似手机九宫格的英文输入控制(MSP430 keyboard on cellphone)

说明：  答题器源码，用51单片机控制的。具体内容自己下载看吧(Answer source browser, with 51 single-chip control. Download and see the specific content of their own)

随机调制信号下的模拟ppm，基于SVPWM的三电平逆变的matlab仿真，在matlab R2009b调试通过。( Random ppm modulated analog signal under Based on SVPWM three-l)

说明：  用mcs-52系列单片机实现等精度频率测量，T1引脚接被测TTL信号，晶振22.1184MHz，对任何频率都可以实现很高精度的测量（精度<1 )，结果从串口字符串输出，波特率115200，可以用串口调试器观察结果.(With mcs-52 family of single chip and other precision frequency measurement, T1 pin then measured TTL signal, Crystal 22.1184MHz, any frequency can be achieved very high accuracy of measurement (precision<1 ), the result string from the serial output , baud rate 115200, serial debugger can observe the results.)

通过DS18B20读取温度（范围-55C~125C，精确到小数点后一位），通过4位数码管显示出来。 当温度为正且百位为零时，不显示，当温度为负时百位显负号。当温度百位和十位都为0时0都不显示。(Read through the DS18B20 temperature (range-55C ~ 125C, accurate to one decimal), through four digital tube display. When the temperature is zero and 100, do not show, when the temperature is significantly negative at minus 100. When the temperature is 100 and 10 are not displayed 0:00.)
