在51单片机中用C语言描述IIC总线的功能，以LED发光二极管表现(51 single-chip using C language to describe the functions of the IIC bus, the LED light-emitting diode performance)

汽车安全与防盗最初的电子化开始于1994年的引擎防盗(IMMO)，恩智浦半 导体(当时的飞利浦半导体)作为第一家半导体公司把RFID的电子标签技术成功 的应用于汽车电子引擎锁：通过汽车与钥匙间的125kHz的无线通讯实现电子身 份识别，来判断启动汽车引擎。这一技术极大的提高了汽车的安全性，很快就在 欧洲以及北美地区广泛应用，并在短短几年时间内使欧洲的汽车失窃率大幅降低 了90 ，因而成为整个欧洲的汽车标准配置(Automotive safety and anti-theft electronic originally began in 1994, engine anti-theft (IMMO), NXP (then Philips Semiconductors) as the first semiconductor company to RFID electronic tag technology successfully used in automotive electronic engine lock: By car keys between 125kHz and wireless communications for electronic identification, to determine start the car engine. This technology greatly improves the car' s safety, soon in Europe and North America, widely used, and in a few years time so that European auto theft rate significantly reduced by 90 , and thus the entire European automotive Standard configuration)

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)

一个温度控制程序实现温度传感器的测控，容易套用(A temperature control program to achieve the temperature sensor monitoring)

该程序为数码管静态显示程序。 每按一次 独立按键 中的 T0，数码管的值便会加一(The procedure for the digital static display program. Each time you press the button in the Independent, the value of the digital tube will add a T0)

PHILIPS 22DC 501/00, PHILIPS 22DC 501/00

本程序为完整的用GT911芯片设计的触摸屏程序，可以供开始设计触摸屏的一个很好的参考，值的收藏(This program is complete with the GT911 chip design touch screen program, you can begin to design a touch screen for a good reference value of the collection)

说明：  stm32f429 iic oled mdk环境(Stm32f429 IIC OLED MDK environment)

这是基于stm8s003芯片的 iic slave 模块程序.简单易懂，可以稳定地跑100k的标准iic。适合初学者学习。编译环境是stvd，编辑是sourceinsight。(This is iic slave module program based stm8s003 chips. Easy to understand, can stably run the standard iic 100k. Suitable for beginners to learn. Compiler environment is stvd, editing is sourceinsight.)

this is a program key test
