stm32-DPV3.1-2013.5.1

点阵液晶屏的参考程序，内置菜单动能，大家可以研究一下(Dot matrix LCD screen reference program, built-in menu kinetic energy, we can look)

通过把开机次数记录在24C02中，并在数码管上显示出来， 124C02的写保护脚为低电平，即允许写(Boot number of records in the 24C02, and displayed on the digital 124C02 write-protect pin is low, that is allowed to write)

温湿度串口检测程序，实现对数据的读取和检测(Temperature and Humidity Serial Port Detection Program for Data Reading and Detection)

51单片机测频计 可测1M赫兹一下的方波 有很多不恰当的地方 往海涵 自己敲的代码 新手。。。(The 51 MCU measured frequency meter)

对于闭环控制有很好的说明以及pid算法的具体实现(Specific implementation for closed-loop control has a good explanation and pid algorithm)

说明：  NUAA微机实验课设：1.密码确认。2.数据采集控制系统。3.数码管显示(NUAA Computer Lab located: a password confirmation. 2 Data acquisition and control system. 3 digital display)

由单片机和DAC0832产生正弦波或三角波的程序。单片机和DAC0832可将频率进行分频的具体程序(Sine or triangle wave and DAC0832 procedures generated by the microcontroller. SCM and DAC0832 can divide the frequency of specific procedures)

基于FRDM-KL25Z及简单运放（LM324）设计出了一套小巧、低成本的心电监测装置。它不但能够结合上位机实时显示心电图而且能够将采集的心电信号储存于SD卡，用于24h心电监护，以备观察不同时间段心血管疾病的症状。(FRDM-KL25Z and simple operational amplifier (LM324) based on the designed ECG monitoring device with a set of small, low cost. It can not only combine with the real-time display of the host computer and can store the collected ECG signals in SD card for 24h ECG monitoring for the observation of the symptoms of cardiovascular diseases at different time periods. )

PSCAD风机（异步机带桨距角控制）经过0.69kV-13.8kV-115kV-345kV三级升压，远距离电缆并入主网模型(PSCAD wind )

这个是9342的测试程序，已经调试OK，希望可以帮助有需要的朋友。(This is the 9225 test program has debugging OK, I hope to help a friend in need.)
