使用51单片机以及红外管，这段代码实现小车沿着黑色线路准确行走，但是要自己修改到合适的左右轮速度才能完美转弯。(By using 51 MCU and IR LED light tube, the code can achieve the goal of moving according to the black line. But you need revise the speed data of the left and right tire so that the car can turn aroud perfectly. )

红外遥控解码，基于51单片机的例程，简单实用，我在学习单片机的时候用到的(Infrared remote control decoding, based on 51 MCU routine, simple and practical, I used the time to learn microcontroller)

液晶显示屏OCMG源程序代码，采用的方式为串口驱动。(LCD OCMG source code, the approach for the serial port driver.)

说明：  VB串口通讯实例 高精度电压表(24bit) VB源程序(VB serial communication example high precision voltage meter (24bit) VB source code)

这是有关pwm的控制，可以控制它周期的长短来控制灯的亮度，还可以控制它自动调光。(This is the control of the pwm, the length of the cycle it can be controlled to control the brightness of the lights can also control the automatic dimming.)

本总体方案完成国标GB20600-2006数字电视地面广播传输系统基带部分功能。 输入数据码流经过扰码器（随机化）、前向纠错编码（FEC），然后进行比特流到符号流的星座映射，再进行交织后形成基本数据块，基本数据块与系统信息组合（复用）后并经过帧体数据处理形成帧体，帧体与相应的帧头（PN序列）复接为信号帧（组帧），经过基带后处理转换为输出信号（8MHz带宽内）。该信号经变频转换为射频信号（UHF和VHF频段范围内）。用C程序设计了图形交互界面，可以在界面上直接设置调制参数。(The overall program completion GB GB20600-2006 digital terrestrial television broadcasting transmission systems baseband function. The input data stream through the scrambler (randomization), forward error correction (the FEC), then the symbol constellation mapping bitstream to the stream, and then after forming the basic block interleaving, the basic data block and information combined system ( multiplexing) after data processing and after the frame body forms a frame body, frame body with a corresponding header (PN sequence) multiplexed signal frame (framing), after post-processing baseband signal is converted to an output (internal 8MHz bandwidth). The signal is downconverted to a radio frequency signal (in the VHF and UHF frequency range). C program designed graphical interface, you can set modulation parameters directly on the screen.)

C51单片机RTC实时时钟(DS1302)初始时间12：00：00数码管显示(The initial time of the the C51 MCU RTC real time clock (DS1302) 12:00:00 digital display)

说明：  430里示例程序中的一个,对初学者来说,是一个很好掌握430 的一个好程序(430 procedures in a sample, for beginners, it is a very good grasp of a good procedure 430)

针对RN8209新型电表计量芯片的校表软件，使用DLT645-2007通讯协议(RN8209 for new electricity metering chip calibration software, communications protocols using DLT645-2007)
