矩阵按键测试程序, 输出结果用串口传输到上位机显示(Matrix key test program, the output with serial transmission to the PC)

DS18B20温度换算器，可以检验单片机传感器检测出来的值。注意，是VB.net源码。(DS18B20 temperature converter, you can test the value of single-chip sensor detects.Note it is VB.net source.)

CS5460A芯片源程序，能测量电流、电压以及电能等量。(CS5460A chip source program, which can measure current, voltage and equal power.)

说明：  一个求二维格点模型热传导的程序，可以求温度分布和热导率(a program to get the theomal conductivity in 2D lattice madel)

stm32f4 的usb鼠标主机程序，简单的修改即可成为自己的工程(stm32f4 usb mouse host)

数据转换为正弦图，最终输出的正弦图为平均正弦图。(Data into sine figure, final output sine the graph is the average sinogram.)

使用51单片机，用其内部定时中断，和外部中断只找一个可控脉宽调制信号PWM(Using 51, with its internal timer interrupt, and external interrupt only to find a controllable pulse width modulation signal PWM)

PT2262是一款功能强大的单片机，我所上传的是芯片的资料，希望能对大家有所帮助(PT2262 is a powerful microcontroller, is the chip I have uploaded the information, hoping to be helpful)

宽频放大器,有以下功能: 预置增益,增益加/减,显示输出电压有效值,自动增益 显示有效值. 增益输入及加减 自动增益没有实现(Wideband amplifier has the following functions: Preset gain, gain plus/minus, the display output voltage RMS, automatic gain display rms. AGC gain input and subtraction is not implemented)
