Profibus-DP从站原理图， VPC3芯片配合STM32F103RBT6的系统，AD6原理图格式。(Profibus-DP slave schematics, VPC3 chip with STM32F103RBT6 system, AD6 schematic format.)

该程序是CRC校验程序，可以查看文件的校验和，这对文件本身进行校验，也可用在其它程序中检难数据正确与否(CRC procedures can view the document and check that the document itself calibration, but also can be used in other programs Frederick hard data are correct or not)

iCan4017模块改进程序，语言Windows Visual C++(iCan4017 programme, Windows Visual C++.)

新编MCS-51单片机应用 完本。 希望对大家有用(New MCS-51 microcontroller applications complete this. I hope useful)

PIC （PIC16F886） 做的简单频率计 用TMR0定时1s，将待测信号从T1CKI脚输入，用TMR1进行计数，读出TMR1H，TMR1L的值就是频率 单片机：PIC16F886 显示：LCD1602 编程语言：PIC C 附Proteus仿真。(PIC (PIC16F886) to do a simple frequency counter TMR0 timer with 1s, the test signal input pin from T1CKI with TMR1 count, read TMR1H, TMR1L value is the frequency of the microcontroller: PIC16F886 display: LCD1602 with Proteus simulation.)

Infi-90读写测试，在安装有COPOSER的计算机上可以运行，采集ABB DCS的控制逻辑块上的数据。(Infi- 90, speaking, reading and writing test, the installation of COPOSER can run on a computer, the data on the acquisition of ABB DCS control logic block.)

AVR,JTAG仿真软件，内涵源程序和电路图，直接烧写进单片机就可以在线仿真的(AVR, the simulation software of JTAG, content of the source code and circuit diagram, directly burned into the microcontroller can online simulation )

该项目首先是利用单片机对鱼缸的温度进行智能控制。首先通过外部按键对鱼缸所需温度进行设定。温度传感器 DS18B20 采集温度信息在外围的 LCD 上显示出来。其次是利用光电耦合器判断有无鱼饵，若无鱼饵，发出提示，若有鱼饵，则执行自动投食或手动投食功能。(The project first is the use of single-chip microcomputer to control the temperature of the fish tank. First, the temperature of the fish tank is set by the external button. The temperature sensor DS18B20 collects the temperature information to display on the periphery LCD. Followed by using photoelectric coupler to determine whether the bait, if there is no bait, alert, if there is a bait, automatic throw in and throw food or manually cast and functional food.)
