Hi,
I have started to design circuit, it consists of micro controller , amplifier and speaker .
My main goal is to play the recorded information at different frequencies (say from 15 to 25kHz) micro controller has pre loaded payload data (data, this data is like ultrasonic information stored in micro controller memory ) , I want to send this at the particular frequently to play this through speaker via audio amplifier..
So now my worry to select system requirements.. Is it possible to play info at frequencies just using micro controller and audiampli,, speaker ..? Do i Need to go with any audio codecs?
regards
Ravee
