STM32F407信号发生器输入一个正弦波，AD采样，DA输出，系统频率应该是输入的波形的频率的10倍以上保证输出波形的完整性，系统的输出频率可以使用示波器测试出。(Stm32f407 signal generator input a sine wave, AD sampling, Da output and system frequency should is 10 times the frequency of the input waveform to guarantee that the above output waveform of integrity, the output frequency of the system can use oscilloscope to test out. )

用C语言实现matlab的butter函数中低通和带通功能,高通和带阻没写,有兴趣的可以自己加入.(Using C language to achieve matlab butter function low-pass and band-pass function, high pass and band stop did not write)

内核重载过TP（看雪大牛作品，非常完整）(Kernel overloaded over TP (see snow Daniel works very complete))

虚拟串口，在Proteus中可用实际串口与其通信(Virtual serial port, available at Proteus its actual serial communication)

51单片机编程器制作资料。内有pcb，原理图，物料清单，hex文件。自制成功(51 Microcontroller Programmer production of information. There pcb, schematics, BOM, hex file. Self-made success)

基于51的C语言频率计，内涵仿真图，以实现空能(Based on 51 C-language frequency meter, meaning simulation diagram, in order to achieve air can)

基于AD8402的数字电位器，可以拟补模拟电位器进度不够的缺陷，从而提高系统的精度(AD8402 based on the digital potentiometer, can fill to simulate the defects, schedule enough potential to improve precision of the system)

这是有关pwm的控制，可以控制它周期的长短来控制灯的亮度，还可以控制它自动调光。(This is the control of the pwm, the length of the cycle it can be controlled to control the brightness of the lights can also control the automatic dimming.)

读取ssdt函数当前地址，详见源码中、。。。。(Ssdt function reads the current address, see the source code. . . .)
