[Algorithm] FFT2D

Description: 2dFFT的奈奎斯特频率为，（为采样间隔）实际上的FFT变换点数要求为2的n次幂，各点所对应的频率是从到，求出后，可以用，这里N为FFT变换的点数。如变换点数为2048，由于对称性，实际有用的点数为1024个。在该程序中，做完富氏变换后，已经将数据按照频率从0到到0的顺序排好。在运行结果中，只需存储左下角的1/4区域的数据即可。 -2dFFT of the Nyquist frequency, (for the sampling interval) is actually the FFT, the n number of points required for the power of 2, the frequency corresponding to each point is to, find, you can use the FFT, where N points. Such as the transformation point to 2048, due to the symmetry, the actual useful points to 1024. In the process, done after the Fourier transform has the data in accordance with the frequency range from 0 to 0 in order to line up. In the run results, only the lower left corner of the store 1/4 of regional data can be.

[android] FFT_bluetooth

Description: 此代码由eclipse开发，应用于android手机，原本用于将单片机通过蓝牙串口传来的1024个数据进行FFT变换，然后显示出电机转速值，就是频率值的60倍，蓝牙串口和FFT是难点，如果打开工程发现提示错误，要求API5，可以设置那不报错，正常运行，API5为舍弃掉的一个API-Developed by the eclipse, this code applies to android phone, originally used for the microcontroller via Bluetooth serial data from the 1024 FFT transform, and then shows the motor speed value is 60 times the frequency value, the Bluetooth serial port and FFT is difficult, If you open the project found to prompt errors the requirements API5, you can set that is not an error, normal operation, API5 discard an API
