Hi Dennis. thank you for your reply. Unfortunately I live in Iran and I can't go to TI website. I wanna get the audio with 6 ADMP401 microphones and a BBB. I couldn't go to the TI website and couldn't find proper documents on other sites. so I don't know how to work with PRU and ADC. please, help me somehow if possible.
