Hello Sidrah, I've added some comments to the adc_rec and dac_play source to indicate which STM32F4 pins the signals connect to.
They don't connect to the Discovery board microphone or PCM codec. I imagine there are examples available from STM for using these devices. the profile programs are for profiling (measuring the execution speed), they don't do any I/O. sm1000_main.c is the closest to what you want. What is your application? - David On 20/04/15 20:33, Sidrah Javed wrote: > 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.
