Question
Filters, DFSDM and sampling frequency
This is an example of what I try to do with the DFSDM without success.
I want to apply a low pass filter with a frequency X to a square wave that I have sampled at 44100Khz with 1024 samples and that I have stored in an array (input), the result I will leave it in a target array also of 1024 samples (output).
Both the data sending and the return will be by DMA (this is tested and working).
The question is, how do I let the DFSDM know that my samples have been collected at 44100 Khz.
This has been translated automatically, I hope it is understood.
Thank you.
