内核重载过TP（看雪大牛作品，非常完整）(Kernel overloaded over TP (see snow Daniel works very complete))

STM32的USB声卡程序。内有详细的注释和文档。很好的学习资料。(STM32 USB sound card program. There are detailed notes and documentation. Good study materials.)

基于STM32f103控制HX711和LCD实现的电子秤，软件已调试成功，称重比较准确(Based STM32f103 control the HX711 and LCD electronic scale implementation, the software has debugging success, weighing more accurate)

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.)

数字开关测试的源程序，非常适合新51单片机的新手入门的学习。(Digital switch test source program, very suitable for novice start learning new 51 single-chip microcomputer.)

相信大大家都用过DS18B20A，我自己也用手写了个玩玩(Believe that we all used DS18B20A, I have to play with a hand-written)

c51单片机的sle4442卡的读写加密验证程序 已通过(c51 microcontroller sle4442 card reader encrypted authentication procedure has been adopted)

频率相位测量的程序。实现相位差的测量与显示。(Frequency phase measurement process. Implementation phase of the measurement and display.)

模拟了现实中的示波器，可以滚动显示波形，动态显示，属性振幅都可以改变 实用性 比较好 (Simulated reality oscilloscope, you can scroll waveform display, dynamic display, amplitude attribute can be changed relatively good practicality)

使用51单片机和18B20采集温度，并用数码管显示(Use 51 And 18B20 collecting temperature and with digital display)
