说明：  基于stm32L151核心板的LoRa无线传输(LoRa wireless transmission based on stm32L151 core board)

说明：  LED数码显示器C51编程.共四个例子,这是第一个.供大家参考(LED Digital Display C51 programming. A total of four examples, this is the first. For your reference)

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.)

利用51单片机实现无线通信程序，测试可用(Using 51 single chip wireless communications procedures, testing available)

利用DSPTMS320LF2407产生PWM波，其输出波形为方波(Produced by DSPTMS320LF2407 PWM wave, the output waveform is square wave)

基于51单片机控制的时间继电器C源程序，调试OK，请放心使用哦(MCU controlled relay)

ad5306是adi公司生产4路8位的DA转换器,它采用IIC接口,操作简单,稳定性可靠 本程序为它的驱动程序 (Ad5306 is adi company in the production of 4 road 8 DA converter, it USES the IIC interface, simple operation, reliable stability of this program for its driver )

一个ModBus单片机例子 使用AVR(And a ModBus SCM example)

液晶例程， 包括画点画线画缓冲条，在液晶上printf的算法(LCD program world，you can study LCD draw points )

基于nuc900的读以太网程序源代码。可作为参考和移植。(Based on the nuc900 read Ethernet program source code. Can be used as reference and transplantation.)
