RS485通讯代码,主机从机都有,调试通过绝对可以用(RS485 communication code, the host from the machine have, debugging can be used by an absolute)

本文介绍了一种基于51单片机的小车寻迹系统。该系统采用两组高灵敏度的光电对管，对路面黑色轨迹进行检测，并利用单片机产生PWM波，控制小车速度。测试结果表明，该系统能够平稳跟踪给定的路径。(This article describes a 51 MCU-based car tracking system. The system uses two sets of high sensitivity photoelectric tube, on road black track detection, and the use of single-chip PWM wave to control the car speed. The test results show that the system can have a smooth track the given path.)

数字控制输出直流电源（含c源码以及原理图）(CNC DC Power Supply)

这是单片机C语言的源码，稍微有点复杂，但大家仔细看，能够看懂(This is a single-chip C language source code, a bit complicated, but we look carefully, to understand)

说明：  S7-1200 PLC程序，PID闭环恒压供水PLC程序(PID closed loop constant pressure water supply PLC program)

基于单片机控制的波形发生器系统的程序，有频率显示等功能(Microcontroller-based waveform generator system procedures, frequency display and other functions)

产生级数为4的M序列，P1输入4个初值，在数码管上显示出来，单片机模拟产生伪序列码(produce series for the M-4 sequence, P1 four initial input, the digital control on the show. SCM simulation of pseudo-sequence code)

一个单片机应用的代码，可实现基于单片机的温度数码管显示，经验证可编译通过并实现(A microcontroller application code, enabling microcontroller-based digital temperature display, proven to compile and implement)

利用stm32输出pwm波，希望能给大家带来一些帮助(Output PWM wave by stm32)

T2 定时器应用简例，利用T2定时器控制小车的调速与测速功能的新定时办法(T2 timer application simple example, the use of the T2 timer to control the car' s speed and the speed function of the new timed approach)
