DAC5615的使用，能够控制输出电压为设定电压，并保持恒定。(DAC5615 used to control the output voltage setting voltage, and constant.)

辅助数字电路课程学习，说明TTL电路中驱动电流之间的 关系。 (auxiliary digital circuit courses on TTL circuit-drive current relationship.)

说明：  定时器的使用，让你了解使用定时器所必须的几个步骤！从而能够使用(the use of timers let you know by the use of timers to be a few steps! In order to use)

3． 参考void Reverse(LinkQueue &Q)函数，定义新的函数int Palindrome_Test(char str[])，判断字符串str是否回文序列,若是则返回1,否则返回0。写出程序或用文字描述算法的执行步骤。(3. Reference void Reverse (LinkQueue & Q) function, define a new function int Palindrome_Test (char str []), to determine whether the string str palindromic sequence, if it returns 1, otherwise it returns 0. Written procedures or describe in words the steps of the algorithm.)

基于VISA的，采用lan口通信的，安捷伦示波器读取数据的程序。(VISA-based, using the lan port communications, Agilent oscilloscope program to read the data.)

GUI用户界面用来显示电路波形，即示波器，STM32编程实现(STM32 and GUI for application to show electronic waves accounting for testing the circuits.)

使用ADC0832和STC89C51单片机实现AD采集(Using ADC0832 and STC89C51 microcontroller AD collection )

基于m16的温度控制系统，主要用ds18b20(failed to translate)

能从SD卡读取MP3文件，并且识别后通过LD3320播放MP3，具体使用只需新建一个.ini系统文件存在sd卡，在里面设置好关键词并且所需播放的MP3文件即可(Read MP3 files from the SD card through the LD3320 play MP3 and identify specific use simply create a new the ini system files sd card exists inside set keywords and required to play MP3 files can)

说明：  本PDF文件为市电电压频率测量计的设计说明书！从中能了解相关的电路设计(The PDF file is mains voltage frequency meter design manual! From which to understand the relevant circuit design)
