我们最近做的实验-our recent experiments

实现dds的步进控制 步进100hz 步进值可调 -Dds realize control of the stepper stepper stepper 100hz adjustable value

从输入文件如in.txt读取数据，经com1端口发送（自发自收），收到的内容存入输出文件如out.txt。 在按键后启动发送，并开始计时，发送完毕后，结束计时，并显示发送所花时间。

非常不错的初学者看的程序有硬件设计哦。我是菜鸟为了成为会员花了不少心事-very good look at the procedures for beginners hardware design oh. I was a birdie to become a member spent a lot of feelings

数字频率调制又称频移键控（FSK），二进制频移键控记作2FSK。数字频移键控是用载波的频率来传送数字消息，即用所传送的数字消息控制载波的频率。2FSK信号便是符号“1”对应于载频，而符号“0”对应于载频（与不同的另一载频）的已调波形，而且与之间的改变是瞬间完成的。 -Digital frequency modulation called frequency shift keying (FSK), binary frequency shift keying recorded as 2FSK. Digital frequency-shift keying is the carrier frequency to transmit digital information, that is, the number of messages transmitted with the control of the carrier frequency. 2FSK signal is the symbol of "1" corresponds to the carrier frequency, while the symbol "0" corresponds to the carrier frequency (with a different carrier frequency to another) and modulated waveform, but also between the change was instantaneous.

（1）该码功能是将数组后n为一次放在数组前面，不改变其他元素顺序； （2）用二分法求方程的根。-(1) of the code after the function is an array on an array of n for the first time in front of the other elements do not change the order (2) equation for the root of the dichotomy.
