Posted on October 16, 2014 at 17:02Hi,I'm using CMSIS DSP Libraries with a microcontroller STM32F4 to compute FFT. Here is my function code to compute the FFT:void fftProcess(float32_t *parSignalInput_f32, float32_t *parfftOutput_f32){ uint16_t i...
Posted on October 17, 2014 at 08:41Thanks Clive1 for this first clue,I do not use dynamic memory (heap) in my program. arm_cfft_f32() and arm_cmplx_mag_f32() are two functions from the CMSIS DSP Libraries provided by ARM. So I do not know if DMA is ...
