Description: 目前市场上有很多语音录放系统，如录放音玩具、录音笔等，大多采用了单片机控制一个语音芯片，再接一个FLASH存储器的结构。单片机可以控制录放时间，选取特定时间段的播放以及单多声道的录放，容易通过改变外接存储FLASH改变录放时间。
我们做的是一个简单模型，只能录放。
只需要录音和放音时的外部 ROSC 端振荡电阻不同就能改变声音的录入和播放速度，录入的时间越短音质越好，录入的时间越长音质越差
它采用模拟量直接存贮技术，因此保真度高，音质好
-Currently on the market there is a lot of voice recording systems, such as sound recording toys, sound recording pens and so on, most of the single-chip microcomputer to control the use of a voice chip, making the structure of a FLASH memory. Single-chip microcomputer can control the playback time, select a specific period of time many of the players, as well as single-channel recording, easy to FLASH memory by changing the external playback time change. We make a simple model, only playback. Required only when the recording and playback-side oscillation of the external resistor ROSC will be able to change different recording and playback of sound speed, the shorter the time of admission, the better sound quality, longer recording sound worse using direct analog storage technology, Thus the high-fidelity, better sound quality

Description: 蜂鸣器响声频率测试程序
作用：因为蜂鸣器在市面买回来频率相近，但不同批次与不同厂家都有分别，
导致一个通用的程序无法发出量理想的响声，而且多是不在最佳频率
时响声就变得很小。本程序就是通过串口从PC中手动输入不同的值,
得到清脆响亮的最佳参数。使用时直接用该参数取代A即可，程序中
已有详细中文注释，非常方便。（常用值在88左右）

This procedure is through the serial port from a PC to manually enter different values get the best parameters sonorous. When using the direct use of this parameter can be replaced by A, the program a detailed English notes, very convenient. (Common values of the 88 or so) Author: Bo waves Time :2010-01-18

Description: AT89S52单片机控制的超声波测距，主程序首先对系统环境初始化，设置定时器T0工作模式为16位的定时计数器模式，置位总中断允许位EA并给显示端口P0和P2清0。然后调用超声波发生子程序送出一个超声波脉冲，为避免超声波从发射器直接传送到接收器引起的直接波触发，需延迟0.1ms(这也就是测距器会有一个最小可测距离的原因)后，才打开外中断0接收返回的超声波信号。由于采用12MHz的晶振，机器周期为1us,当主程序检测到接收成功的标志位后，将计数器T0中的数（即超声波来回所用的时间）按下式计算即可测得被测物体与测距仪之间的距离,设计时取20℃时的声速为344 m/s则有：
d=(C*T0)/2 =172T0/10000cm（其中T0为计数器T0的计数值）
测出距离后结果将以十进制BCD码方式LED,然后再发超声波脉冲重复测量过程-AT89S52 MCU-controlled ultrasonic ranging, the main program first initializes the system environment, set the timer T0 mode for 16-bit timer counter mode, the set EA and the total Interrupt Enable bit ports P0 and P2 to show clear 0. Then send a subroutine call occurs ultrasonic ultrasonic pulses, in order to avoid direct transmission of ultrasound from the transmitter to the receiver caused by the direct-wave trigger, must delay 0.1ms (This is the range-finder will have a minimum measurable distance reasons) after the Only open the external interrupt 0 to receive the returned ultrasonic signals. As a result of 12MHz crystal, the machine cycle 1us, when the main program detects that received flag of success, will be the counter of the number of T0 (ie, used ultrasound back and forth time) determined by the formula and the measured object can be measured measured from the distance between the instrument, designed to take 20 ℃ when the speed of sound is 344 m/s there are:
