AD9850 AD 9851 并行 串行控制程序 很好的资料 以前自己花钱买的啊 (AD9850 AD 9851 serial parallel data control procedures well before the own money ah)

模拟PWM信号控制小灯，控制二极管占空比(Analog PWM signal control light)

51单片机数码管静态显示，计数器功能，学习如何对数据管进行操作(51 MCU digital static display, the counter function, learning how to operate the data management)

DDS9850，亲测可用，有中文解释，信号发生器(DDS9850, pro-test is available, there are Chinese explanation, the signal generator)

基于单片机的可燃气体报警器，反应灵敏，报警及时(Based on the single-chip microcomputer combustible gas alarm, sensitive, timely alarm.)

通过51单片机实现串口通信，并在外接LED显示器上显示。(51 microcontroller via serial communications, and displayed on an external LED display.)

基于STM32F103VET6的无刷直流电机控制程序和资料还有原理图(Brushless DC motor control procedures)

RS485通信的源代码，可进行两个系统之间信号的传递，介绍其编程规则(RS485 communications source code, can be passed between the two signal systems, introduces its programming rules)

说明：  本系统以单片机AT89C51为主体,由芯片插座、独立按键、74HC573驱动8位数码管显示、5V直流电源控制模块等组成。根据数字集成芯片的引脚特性以及集成芯片的真值表编写检测程序。该系统能完成14脚以内常用TTL74系列数字集成芯片的功能测试。(This system is the main body of the single-chip microcomputer AT89C51, the chip socket, independent buttons, 74HC573 Driver 8 digital control, 5V DC power control module and so on. According to the characteristics of the digital chip and the chip s true value, the program is written in the chip.. The system can complete the functional test of the TTL74 series digital IC chip in 14 feet.)

此设计模拟工业控制现场，通过调节Labview界面中的模拟仪表，通过RS232串口通信，把转速控制信息通过串口传送到单片机中，进而利用单片机控制电动机的转速。(labview-based PWM motor speed)
