AUDIO CODEC PROTO
The AUDIO CODEC PROTO additional board enables the microcontroller to be connected to a microphone and
headphones via I2C and SPI serial communications.
Key features:
How to connect the board?
The additional board is connected to a microcontroller via pads CN2. A 3.5mm connector CN23 is used to connect a
microphone, whereas the CN22 connector is used to connect earphones.
How to use the board?
The board is used to convert digital audio recording into analog audio signal that is reproduced via headphones. It
is also used to convert analog audio signal from microphone into digital audio recording. Data transfer between the
microcontroller and additional board is performed via the Serial Peripheral Interface (SPI), whereas the operation of the
board is controlled by the microcontroller via I2C communication.
