2的20次方的快速傅里叶变换

说明：  内容拖放的演示, 主要实现列表内容之间的拖放交换(Drag and drop the contents of the demonstration, list the contents of the main drag and drop between the exchange)

用于在线仪表的 modbus,仅供参考，(online instrument for modbus connection, for information purposes only, thank you)

说明：  如AT040flash的的初始化，读操作，写操作，扇区擦除等(If the AT040flash initialization, read operation, write operation, sector erase, etc.)

代码对比软件，可以比较源码被改动的地方,可以比较单个文件，也可以比较文件夹。

一篇非常经典的LEACH协议改进文献，值得大家学习，在此与大家共享。(It is a very useful book that about LEACH protocol! You can study it and get you want.thank you!)

Exercise 10: Pointers 1. Write a program that reads 5 integers into an array, and then uses four different methods of accessing the members of an array to print them out in reverse order（倒序）.(Exercise 10: Pointers 1.

脉冲激光测距系统工作原理即单片机控制激光发 射装置发射占空比一定的激光脉冲，其中一小部分能量 到达接收电路，然后光电探测器将微弱的光脉冲信号变 成电脉冲信号并看作Start信号触发时差测量。激光的 大部分能量在空间中传播，遇到目标物后反射传播到 达接收电路，看作Stop信号结束测量，至此完成时差测 量[2]。TDC?GP22芯片记录Start脉冲到Stop脉冲之间的 时差，用于计算目标物到发射端的距离。(The principle of the pulse laser range finding system is that the single-chip microcomputer controlled laser emission device launches a certain laser pulse, in which a small portion of the energy reaches the receiving circuit, and the photodetector turns the weak light pulse signal into the electric pulse signal and is considered as the time difference measurement of the trigger time of the Start signal. Most of the energy of the laser propagates in the space. After the target, the reflection transmission reaches the receiving circuit, which is regarded as the end of the Stop signal and then completes the time difference measurement [2]. The TDC GP22 chip records the time difference between Start pulse and Stop pulse, which is used to calculate the distance between the target and the transmitter.)
