• CMSIS-DSP: question about FFT and the frequency bin example
    Hi, I hope this is the right place to ask about DSP/FFT. I'm digging deeper into CMSIS-DSP and managed to get the FFT frequency bin example to work on a Cortex-M3. I have a few questions about CMSIS in...

  • C51 Cooley-Tukey FFT not giving same output as C89 implementation
    I made a FFT program that takes data from inside a buffer, performs FFT, and spits out the equation form. The C89 (ported from C99) version works well, but when I use the EMF8LB1 board to run it after...

  • FFT algorithm
    Hello everyone. I write FFT, it's ran! But it run very slow speed, I try on STM32F103C8T6 72MHz and used timer to measure time, the result about 360ms and I can't run another program. Somebody help me...
