Description: 很有意思的一个单片机程序
用AVR（MEGA16）和BEEP演奏两只老虎
使用了MEGA16的具有PWM功能定时/计数器2
比较输出结果有OCR2管脚输出，即将蜂鸣器连接到OCR2对应的I/O口上即可
这是我自己参照简谱和不同音符对应频率将两只老虎这首歌转成程序
-Very interesting program with a single-chip AVR (MEGA16) and BEEP two tigers used in concert with the PWM function MEGA16 timer/counter 2 compare output pin has OCR2 output, buzzer is about to connect to OCR2 corresponding I/O mouth on you This is my own notes by reference to the corresponding numbered musical notation and different frequencies will be two tigers the song into procedures

Description: 基于AVR单片机的电力谐波分析系统本设计采用ATMEL公司的ATmega32L单片机完成一个电能质量检测系统。电压信号经过变压器隔离降压，幅值较低的交流信号再通过运算放大器构成的加法器变成可供A/D转换电路转换的直流信号。单片机使用内部的定时器每1/3200秒对电压信号采样一次，用片内自带的10位精度A/D转换器对每周波的电压信号采样64个点后，进行FFT运算，FFT的运算过程采取查表法进一步提高运算速度，分析出小于21次的各次谐波的含量，并计算出电压信号的有效值(RMS)，将谐波分析结果通过RS-232串行接口上传到上位机并显示存储。-
This design uses ATMEL Corporation ATmega32L MCU to complete a power quality detection system. Voltage signal through a transformer-isolated buck, lower amplitude AC signal through another operational amplifier adders into a DC signal of A/D conversion circuit for conversion. After the MCU internal timer every 1/3200 second voltage signal is sampled once with chip comes with 10-bit precision A/D converter for sampling a voltage signal per cycle of 64 points, the FFT computation, FFT calculation uploaded to the host process to take up table method further improve processing speed, analyze the content of less than 21 times each harmonic, and calculate the RMS voltage signal (RMS), harmonic analysis results via RS-232 serial interface storage and display machine.
