介绍了用RS

本程序使用P89V51单片机利用起PCA功能对脉冲宽度可调，实现两路输出，加LED显示和按键功能，详细请看程序注释，编程风格自认可以-This procedure since the use of PCA use P89V51 Singlechip feature adjustable pulse width to achieve two-way output, plus LED display and button functions, see the detailed program notes, programming styles can themselves

本文件代码的开发环境是keil C，芯片是AT89S52，这是一个如何使用DS18B20温度传感器的例子，从中可以学习如何利用I2C以DS18B20通信。-This document is a code development environment keil C, chip AT89S52, this is a how to use the example of DS18B20 temperature sensor, which can learn how to use I2C to DS18B20 communications.

这是“led广告屏”程序，已经成功调试，希望对大家有用，谢谢！（最好配合51单片机和伟福编译器）-"led advertising screen" program has been successfully tested and we hope to useful, thank you! (Preferably with 51-fu SCM and compiler)

这是一个关于PS2的C语言程序，利用单片机进行调试，非常好用-This is a C-language program on the PS2 using the microcontroller for debugging, very easy to use

51上运行UCOSII，你要是想移植，但是不会，可以看看，有启发-51 UCOSII run, if you want to transplant, but will not, can see that enlightening

有些实际应用中可能用的C原码,希望对大家有所帮助:(1)并行接口电压输出型DA转换器的控制(2)并行接口电流输出型DA转换器的控制(3)串行接口电压输出型DA转换器的控制(4)5I2C接口的AD及D A转换器的应用(5)基于AD9850的数字信号发生器(6)直流电机的开环控制(7)直流电机的闭环控制-Some practical applications may be used in the original C code, we want to help: (1) parallel port voltage output type DA converter control (2) parallel port current-output type DA converter control (3) serial interface Voltage output type DA converter control (4) 5I2C interface AD and DA converter applications (5) is based on AD9850 digital signal generator (6) open-loop DC motor control (7) closed-loop DC motor control

此程序为利用mage8 AVR 和EM4094实现读取TYPE A类型卡的C程序、读卡稳定、这个项目我们做了好久、非常不错的程序、很适合做这方面产品的朋友们参考-This procedure for the use of mage8 AVR and achieve EM4094 read TYPE A type of card C procedures, reader stability, the project we have done for a long time, very good program, it is suitable for products in this area refer to my friends

Keil C51 上51系列单片机优化的CRC－8 算法。可以自己改其他算式的，包含字节查表，半字节查表，bit计算。很难得的哦。-Keil C51 on the 51 computers optimized CRC-8 algorithm. Other formula can do it ourselves, and look-up table contains the byte, half-byte look-up table, bit computing. Hard to come by Oh.
