用C语言对LED灯进行测试 通过实际按下键盘进行测试笔(the test of LED with C language and the keyboard is a necessity )

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. )

编写一段程序 统计从1000年到1999年之间闰年的个数 最后输出到屏幕上来(writing a program to sum up the numbers of leapyear between 1000 and 1999.Finally,showing the result on the screen.)

基于STC 51单片机做的灭菌器，传感器PT100，PID控温，滑动平均算法处理等包含eeprom底层程序(STC5620AD include PID and eeprom)

说明：  stc系列单片机的开发例程 各个模块都跳通过了 开发环境是 keil3(STC series MCU development routines in all modules jump through the development environment is keil3)

该程序作用：将后缀为了；lrc的歌词文件，转换成 ulead 会声会影10.0 中的歌词导入文件（后缀为utf)。使用方法：先在文件中打开 .lrc 文件，然后开始转换，完毕可以查看结果，转换后的文件以 .utf 保存在同一目录下。(role in the procedure : To suffix; Lrc lyrics documents, converted into 10.0 ulead Huiqinghuiying the lyrics into paper (suffix for utf). Use : first opened in the document. Lrc file, and then started to change, can view complete results conversion of documents to. utf preserved in the same directory.)

好的声文同步程序，值得学习，适合于初学者，给大家共同分享(Good sound text synchronization process, it is worth learning, suitable for beginners, for everyone to share)

采用VB编写的一个电路分析系统，支持现行电路的分析，具有电路图绘制，仿真功能，并包含了示波器等元器件。(using VB prepared a circuit analysis system, in support of the current circuit, with circuit diagrams mapping, simulation function, and includes components such as oscilloscopes.)

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)
