The Multimedia
Board features an
audio module providing an interface for
a microphone and stereo headphones. This
module enables audio recording via a mono
microphone. The microphone is connected to
the system via a
3.5mm
connector CN7.
Stereo
headphones are used for audio reproduction. They are
connected to the system via a 3.5mm connector CN6. For
the proper use of microphone and headphones, it is necessary
to write a program and load it into the microcontroller. In
addition to the audio recording and reproduction, the audio module
can also generate a side tone in the headphones. Volume as well as
other functions of this module are controlled by the microcontroller
from within the software using serial
I2C
communication. Communication
between the audio module and the microcontroller is performed via the Serial
Peripheral Interface (
SPI
).
