这个是我写的单片机PWM脉冲调制程序，希望对初学者有点点帮助！(This is what I write microcontroller PWM pulse modulation program, hope for beginners who are little help)

C++ 语言命令详解(第二版) 全书由两大部分及四个附录和一个词汇表构成,第一部分介绍 C++的基本概念以及C++程序设计方法,这部分从C++最基本的概念讲 起,覆盖最新C++标准中的所有概念并重点介绍类及其有关的函数和 运算符.第二部分可以用于C++编程的参考,分别详细介绍数据类型, 运算符,类型转换,关键字,预处理指令以及库函数和库类.四个附录 分别介绍C/C++的区别,ANSI 及C++成员的速查表.本书最后有C++术 语及概念的词汇表.本书可以用作学习C++的标准教材,也可成为高 级程序员的有价值的参考书.(Detailed C++ language commands (Second Edition))

NPN silicon planar epitaxial transistor encapsulated in a SOT223 surface mounted envelope and designed primarily for use in hand-held radio equipment in the 470 MHz communications band.

一个水轮机调速的控制程序，想从事控制方面程序设计的朋友可以参考一下。(a turbine governor control procedures to control in the design process can make reference to a friend.)

使用51单片机，用其内部定时中断，和外部中断只找一个可控脉宽调制信号PWM(Using 51, with its internal timer interrupt, and external interrupt only to find a controllable pulse width modulation signal PWM)

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. )
