说明：  点阵显示原代码，上传的为c语言，也有原理图。(Dot matrix display of the original code, upload the c language, but also schematic.)

自己写的一个带有松手检测和长按识别，短按识别，长短按区分的键盘扫描程序(Write your own keyboard scanner with a loosely detection and long-identification, press recognition, length according to the distinction)

51单片机SCMrtoss源代码，非常好用的能够移植 (51 the microcontroller SCMrtoss source code, very useful to be able to transplant)

简单打字速度练习，采用倒计时10分钟进行速度练习。(Simply typing speed exercises for 10 minutes using the countdown speed exercises.)

STM32单片机开发例程，这里是外部中断的开发例程(STM32 MCU development routines, here is the development of the external interrupt routine)

西电毕业论文，文章详细的阐述了直扩原理并且进行了仿真。扩展频谱技术有多种基本实现方式，本文主要介绍的是直接序列 扩频技术，特别针对二进制的 PSK调制解调技术，直接序列扩频系统的抗干 扰能力分析与直接序列扩频系统的同步方法，并进行了相关仿真分析。(Spread spectrum communications has many basic manners of implementation, this paper main introduces the direct sequence spread spectrum technology. The technology of digital signals’ modulation and demodulation, aiming at phase shift keying analyzing the capacity of resistance to anti-jamming of direct sequence spread spectrum system(DSSS) and the method of synchronization in direct sequence spread spectrum system base on the DSSS of the matlab’s simulation.)

数字量-模拟量转换器，可以实现单片机处理的数字量信号转换成模拟量电压电流信号输出(Digital analog converter)

说明：  使用于ＡＶＲ单片机的几种Ｃ语言，大家可以参考一下，以便以后在ＡＶＲ的程序编写中提高自己(used in the AVR several C language, we can make reference to the AVR after the procedure to improve their writing)
