tea5767收音机原理图，mcu是STC90C52属51系列单片机,原码在网上可搜。(TEA5767 RADIO SCH，MCU IS STC90C52 IN SYSTEM，SOURCE PROGRAM WEB SEARCH )

说明：  比例谐振控制程序，PR控制可用于控制系统中输入量为非常值量的控制。(请键入文字或网站地址，或者上传文档。 取消 Bǐlì xiézhèn kòngzhì chéngxù,PR kòngzhì kěyòng yú kòngzhì xìtǒng zhōng shūrù liàng wéi fēicháng zhí liàng de kòngzhì. 帮助我们改进 Google 翻译Proportional resonant control procedures, PR control can be used to control the system input volume control for very value.)

可以用的飞思卡尔智能车测试程序，非常不错的(Freescale smart car test procedures can be used, very good)

基于51单片机温度传感器源码，经试验验证OK的。(Based on 51 single-chip temperature sensor source code, the test verified OK.)

说明：  用示波器测得比较标准的模拟IIC程序。STM32F103(A standard analog IIC program is measured by an oscilloscope. STM32F103)

本软件是STM32f407芯片的ADC操作软件，采用DMA方式。我已经测验了在STM32f407开发板。为了STM32f开发，很有用的软件(This software is the STM32f407 chip ADC operating software, using DMA mode. I ve been testing the STM32f407 development board. In order to STM32f development, very useful software)

STM32单片机利用DS18B20温度传感器实现温度检测的源码，包括原理图和数据手册(The STM32 MCU DS18B20 temperature sensor temperature detection of the source, including schematics and datasheets)

抢答器论文及其proteus仿真资料 单片机C51程序(Responder papers and proteus simulation data C51 MCU program)

此源码为电脑鼠参赛最后冲刺作品，在比赛中取得良好成绩，可直接参加比赛代码。(The source for the computer mouse competition final sprint work, to achieve good results in the game, can directly participate in the competition code.)

通过单片机输入程序来对步进电机进行控制，以此实现一定功能。(Stepping motor single chip microcomputer)
