基于AVR单片机的MPPT程序（爬山法），非常好用！(AVR microcontroller based MPPT program (hill climbing), very easy to use!)

stm32f103DAC输出两路正弦波600hz 2100hz(STm32f103DAC Outputs Two Sinusoidal Waves 600 Hz 2100 Hz)

说明：  PID control texas insturement

说明：  pcf8591 AD转换程序，可以实现电压表功能，四路模拟输入，一路输出DA输出。(pcf8591 AD conversion process, you can achieve the voltmeter function, four analog inputs, one output DA output.)

利用PROTEUS,在C51单片机上,利用GP2D12测距传感器进行红外线测距的仿真,亲测可用.(Use of PROTEUS, the C51 microcontroller, using GP2D12 infrared distance sensors ranging simulation, pro-test is available.)

基于维格纳分布的Chirplet变换，可用于信号的处理分析，形成时频图。(Based on Wigner distribution Chirplet conversion, it can be used for analysis of the signal processing, the formation frequency diagram.)

神经网络中的权值、阈值以及中间变量很多，但是单片机的程序区和数据区的容量都是有限的。89C52程序区为8K字节，数据区为256K字节。由于探测器受体积限制应尽量避免外扩存储器，所以在实现计算时，要将权值和阈值写成立即数形式减少资源占用。(Neural network weights, threshold and intermediate variables, but procedures for single-chip area and the volume of data are limited. 89C52 process area for 8K byte, 256K-byte data area. As the detector by the volume limit should be avoided as far as possible outside the extended memory, so in the realization of the calculation, the right to the threshold value and written in the form of an immediate reduction in the number of occupied resources.)

说明：  MSP430红外解码驱动，占用了一个定时器资源。(MSP430 IR decoding drive, taking up a timer resources.)
