DAC数模转换，SPI串口通讯，单片机stm32，快速简单(DAC digital mode conversion, SPI serial communication, MCU STM32, fast and simple)

plc 的电梯控制程序，含有组态软件,控制算法。plc 采用三菱fx1n(plc elevator control program, containing configuration software)

51单片机485通信的源代码，C++环境下使用。Proteus仿真软件包，您可以使用程序。(The 51 single chip microcomputer 485 communication source code, the use of C++ environment. Proteus simulation package, you can use the Program.)

此代码为在proteus中仿真代码，实现功能：利用液晶显示时间，通过按键调节时分秒。(This code is a simulation code in proteus. It realizes the function of adjusting the time and seconds by keystrokes using liquid crystal display time.)

说明：  STM32F103系列单片机，编写16路IO控制信号，可直接下载使用。(STM32F103 series single chip microcomputer, 16 channel IO control signal, can be downloaded directly.)

单片机初学者资料 51单片机C语言编程入门(详讲版)(Singlechip beginners )

研华数据采集的一个的demo文件，很好用，可以作为里程看，也可以作为现场采集数据的一个简单程序(Advantech data acquisition a demo file, very easy to use, you can see as mileage, can also be used as the data collected at the scene of a simple progra)

自学stm32笔记，总结配置一些io口，和其他配置文件。(Self - study STM32 notes, summarize the configuration.)

说明：  这是采用stm32L151主芯片驱动NB做云端通信，采用GPS定位。和采集温度。加震动检测。休眠状态达到9umA。(This is the use of stm32L151 main chip to drive NB for cloud communication and GPS positioning. And collection temperature. Add vibration detection. The sleep state reaches 9umA.)

PIC单片机写的红外遥控接收代码，很经典用定时器和中断一起处理的很高效而且定时器还可以用于别的地方，彻底模块化隔离，已经测试绝对可用！(PIC microcontroller code written by infrared remote control receiver, classic together with a timer and interrupt handling is very efficient and the timer can also be used somewhere else, completely modular isolation, has been tested absolutely available!)
