I want to send adc buffer data to Raspberry Pi via SPI. Is there any sample code or any reference? Please help me with this.

I have a 2D array input buffer. so, what is the correct way to implement the rfft and cfft functions?float fftIn[16][512] is my input. So, I applied for a loop like below:arm_rfft_fast_init_f32(&fftHandler, 512); for(int d =0; d<16; d++){arm_rfft_fas...

I am getting nan values while computing the fft. It is mostly for fftOut[0][0]----- fftOut[0][512], after that there are not many nan values. What could be the reason?Is it that because it running in debug mode and the DMA is on?Please help with this...

I am using STM32H723ZG nucleo board. When I enable HAL_ADC_Start_DMA(&hadc1, (uint32_t*)adc_buf, ADC_BUF_LEN); USB Virtual port doesn't show up and when I disable it, it shows up. Can anyone explain what could be the issue?I was able to print "Hello"...

For those of you who might need help with 2D FFT, this is the correct approach.

That is 1D FFT. I have implemented that and getting correct results. I am having doubt in 2D FFT.Below is my question:https://community.st.com/t5/stm32cubeide-mcu/2d-fft-rfft-and-cfft-functions/td-p/587501

Can anyone explain this?

So, if I have a 2D array I need not to put the arm_rfft_fast_f32 function in for loop? I thought it would take ftt one by one along the row.

You are right. In the complete callback function I called system reset function. My Bad!!Thank you so much
