只能小车寻线与避障加寻光51单片机代码，就是全国电子设计竞赛1999年的E题啦。(Only the car line code 51 single-chip microcomputer and obstacle avoidance for light)

ADI芯片CM403、CM408的片上UART例程，包括相关寄存器的设置，有意向使用此类芯片的朋友可以借鉴一下；(ADI chip CM403, CM408 chip on the UART routines, including the relevant register settings, with the intention of using this chip can learn friends )

51单片机AT89C52串行通信.上位机通过串口向单片机发数据，单片机接收后发回给上位机。(51 AT89C52 single-chip serial communication. PC send data through the serial port to the microcontroller, the microcontroller has sent back to the host computer.)

说明：  2015年电赛频率计，优点：简单易实现，精密度高(2015 frequency race frequency meter, advantages: simple and easy to implement, high precision)

应用51单片机控制蜂鸣器产生不同的频率，而形成曲调。(Application of 51 single chip microcomputer control buzzer to generate different frequencies, and the formation of the tunes.)

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 )

3． 参考void Reverse(LinkQueue &Q)函数，定义新的函数int Palindrome_Test(char str[])，判断字符串str是否回文序列,若是则返回1,否则返回0。写出程序或用文字描述算法的执行步骤。(3. Reference void Reverse (LinkQueue & Q) function, define a new function int Palindrome_Test (char str []), to determine whether the string str palindromic sequence, if it returns 1, otherwise it returns 0. Written procedures or describe in words the steps of the algorithm.)

strus开发 短租网,一个小项目，功能不是太完整，但是基本差不多了(a project of struts a project of struts a project of struts a project of struts a project of struts a project of struts)

Binary Bomb Project. Sample bomb and the phases that need to be diffused. Good practice for assembly programming

说明：  电位器输入电压信号，经过ADC转换作为PWM的控制信号，可连续调节直流电机转速(Potentiometer input voltage signal, the ADC conversion as the PWM control signal, Adjustable Speed DC Motor)
