Hi Everyone,
I have been trying to record audio from built-in STM32F4 Mic using
adc_rec.elf and similarly to play audio (.raw file) to STM32F4 Speaker Jack
using dac_play.elf. But unfortunately none of these is working for me.
Firstly, adc_rec.elf does generate an adc.raw file but it does not contain
any speech upon listening through play command. Can any1 help me in
resolving this issue? Is this modulated speech? Or it does not take audio
input from Mic rather from any PIN? If so then which PINs of STM board?
Secondly, dac_play.elf does not play stm_in.raw on the speaker jack of
STM32F4 board. Is it also producing output on some other PINs of STM board?
I have also been working on freedv_tx_profile and freedv_rx_profile. I also
want to know where (At which pins) it gives coded and modulated
transmission output? and from where does it receive reception Input?
I am new in this and could not understand much from the C codes. I will
highly appreciate any help from this forum.
Looking forward for the kind response.
Best Regards
-Sidrah
