CH341 _上位机 VC

一个简单的小车单片机C语言控制，适合初学者(A simple car microcontroller C language control, suitable for beginners)

51单片机片上串口控制GPRS模块。用KEIL 软件调试成功。(51 MCU on-chip serial port to control the GPRS module. KEIL software debugging success.)

这是一个用51单片机系统仿真ucosii工作的protues电路 本系统包括扩展64k RAM的单片机系统和杨屹移植到51单片机的ucosii 系统 使用方法： 1.安装Protues7.4版，然后用protues打开protues 8051 simulation 文件夹 中的extern ram.DSN 文件 2.打开extern ram.DSN 后，双击单片机在弹出的窗口中的Program File 选项 中选择yy.hex文件。 (yy.hex其实就是yy文件夹中keil文档编译出来的hex文 件，yy文件夹是杨屹的ucos51 系统，用keil 2 可以打开) 3.在Clock Frequency选项中输入22.184M(杨屹的ucos51 用的是22.184M hz的单片机频率) 4.双击VTERM串口调试显示屏，在Baud Rate 选项中选择19200的波特率 5.保存，点击运行就可以看到经典的hello world 了。 (1. Protues7.4 version installed, and then open the protues folder protues 8051 simulation The extern ram.DSN file 2. Open extern ram.DSN, double-click the pop-up window of SCM in the Program File option, select yy.hex file. (yy.hex actually yy folder keil out of the document compiled hex files, yy folder is Yang Yi s ucos51 system, using keil 2 Can open) 3. In the Clock Frequency option to enter 22.184M (Yang Yi of the ucos51 using a microcontroller 22.184M hz frequency) 4. Double-click VTERM serial debug display, in the Baud Rate select 19200 baud rate options 5. Save, click Run you can see the classic hello world)

基于单片机MSP430的 步进电机控制 测距程序 (MSP430 microcontroller-based stepper motor control ranging program)

在51单片机上实现RS485通讯，能够实现与上位机的通信(RS485 mode on 51 single, able to communicate with the host computer)

32位单精度浮点数的乘加运算的C编程，感兴趣的可以看一下(Single-precision floating-point multiply-add operation of the C programming, interested can look at)

QuizMaster for viusal basic.

这是基于MSPCC2530的中文版数据手册，非常详细，非常清楚，很适合大家参考，学习(This is based on MSPCC2530 the Chinese version of the data sheet, very detailed, very clear, very suitable for your reference, learning)

三电平SVPWM仿真,运行很好，三电平SVPWM仿真,运行很好，分享给大家( Three level SVPWM simulation, the operation is very good)

上位机恒压供水控制系统，通过MODBUS网络来控制台达PLC(up computer control PLC delta, this software is vell good control software,)
