Any help
Help with PDM to PCM in STM32F407
Hi Mr. Barr,
I have reading your post "Probing PDM: MP45DT02 and STM32F407" and looking in the code, to try using a similar filter than yours in this platform for sampling at 96KHz a modulated signal on a carrier of 16KHz, I can not obtain good results, I dont know if it's not posible or I'm using bad filter parameters cutoff freqs, ....
Do you have any suggest or any example that i could help me with my purpose?
Thanks in advance.
