利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h> unsigned char timer1 sbit PWM=P1^2 void system_Ini() { TMOD|= 0x11 //PWM TH1 = 0xfe //11.0592 TL1 = 0x33 TR1 = 1 IE =0x8A } main() { system_Ini() while(1) { if(timer1>100) timer1=0 if(timer1<30) PWM=0 else PWM=1 } )

说明：  描述了AD9850、AD9851、AD9854、AD9833的调试心得(Describes the AD9850, AD9851, AD9854, AD9833 debugging experience)

STM32F407信号发生器输入一个正弦波，AD采样，DA输出，系统频率应该是输入的波形的频率的10倍以上保证输出波形的完整性，系统的输出频率可以使用示波器测试出。(Stm32f407 signal generator input a sine wave, AD sampling, Da output and system frequency should is 10 times the frequency of the input waveform to guarantee that the above output waveform of integrity, the output frequency of the system can use oscilloscope to test out. )

FreeRTOS_KL16FreeRTOS是一个迷你的实时操作系统内核。作为一个轻量级的操作系统，功能包括：任务管理、时间管理、信号量、消息队列、内存管理、记录功能、软件定时器、协程等，可基本满足较小系统的需要(FreeRTOS is a mini real time operating system kernel. As a lightweight operating system, features include: task management, time management, semaphores, message queues, memory management, recording function, software timer, coroutine, can meet the basic needs of the smaller system)

说明：  NUAA微机实验课设：1.密码确认。2.数据采集控制系统。3.数码管显示(NUAA Computer Lab located: a password confirmation. 2 Data acquisition and control system. 3 digital display)

一个数字类型可提高开关电源的设计与实现，可以是很好的借鉴，但是要用特殊软件打开，把文件后缀复制到百度就可以找到(A digital type can increase the switching power supply design and implementation, can be a good reference, but use special software to open, copy the file suffix can be found on Baidu)

应用程序向导已为您创建了此 Test 应用程序。此应用程序不仅介绍了使用 Microsoft 基础类的基本知识，而且是编写应用程序的起点。(The application wizard has created this Test application for you. This application not only introduces the basic knowledge of the Microsoft class, but also the starting point for the application.)

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)
