i2c procedures can be called directly, with 51 MCU Development.

阀位控制器源程序 利用PIC16F873A-valve controller source use PIC16F873A

proteus仿真的单片机串口通信，请使用虚拟串口软件模拟串口调试，该软件我已经上传。-Proteus simulation of single-chip serial communication, use the virtual serial port serial debugging software simulation, the software I have already upload.

51单片机基础训练项目之会唱歌的单片机。本例使用普通有源蜂鸣器，通过控制单片机输出频率来达到“唱歌”的目的。着重训练初学者对IO管脚的认识。-51 MCU-based training program in the microcontroller will be singing. In this case the use of ordinary active buzzer, by controlling the microcontroller output frequency to achieve the " singing" objective. Focus on training for beginners to the IO pin awareness.

ICCAVR编写128*64液晶程序测试已经通过-ICCAVR the preparation of 128* 64 LCD testing procedures have been adopted

红外通信是利用950nm近红外波段的红外线作为传递信息的媒体，即通信信道。发送端采用脉时调制（PPM）方式，将二进制数字信号调制成某一频率的脉冲序列，并驱动红外发射管以光脉冲的形式发送出去；接收端将接收到的光脉转换成电信号，再经过放大、滤波等处理后送给解调电路进行解调，还原为二进制数字信号后输出。-Infrared communication is the use of near infrared 950nm infra-red as the transmission of information media, namely communication channel. The sending end when the use of pulse modulation (PPM) approach will be a binary digital signal into a frequency modulation of the pulse sequence, and driver fired infrared tube to the form of light pulses sent receiver will receive the pulse of light conversion to electrical signals , and then, after amplification, filtering and other treatment to the demodulation circuit after demodulation, reduced to a binary digital signal after the output.
