库SPRC081。例程主要看了两个,1、controlsuite中定点库fixpiont中的F2833X REAL FFT。2、使用SPRC081中的dspbox中rfft程序(SPRC081中有一个 60user952020-06-03 08:10:50 STM32F4和STM32L4 MCU一起使用是否安全? ,arm_rfft_fast_init_f32() 会返回错误,而 STM32F4 版本则不会。所以我把STM32L4版本...
There is a bad bug in arm_rfft_fast_f32() when your window size is 128. All other window sizes work fine. Below is my code, it appears to result in some kind of infinite loop or memory violation - impossible to say as the board constantl...
arm_rfft_fast_init_f32(&fftInstance, 1024); arm_rfft_fast_f32(&fftInstance, rx_buffer, fft_out, 0); From the official documentation (www.keil.com/.../group__RealFFT.html), I understand that arm_rfft_fast_f32() outputs an array of N=1024 floats: N/2 are the real parts and...
