2.9 24-BIT AUDIO CODEC
Using the WM8731 24-bit Audio Codec, the Multimedia Expansion Board can run appli-
cations that require audio playback and/or recording, as shown in Figure 2-20. For
playing back audio, the Multimedia Expansion Board provides two output jacks, a
headphone and line out jack, which are shown in Figure 2-21. A microphone input jack
is also provided for audio recording. The WM8731 interfaces to the PIC32
microcontroller via the SPI and I
2
C buses.
