6.6. I2S0 Interface Sharing
The I2S0 Interface of the SMARC module can be shared between following sources:
-
I2S Audio Codec WM8904
-
I2S Digital Microphone Connector J39
Note: It is not possible to use both sources at the same time.
I2S0 Interface Switch Modification Instruction
To switch the I2S0 Interface of the SMARC between I2S-Audio and J39 see the
“I2S0 Shared Components
Modification Table”
below. Use
“D001_AssemblyDrawing_eDM-CB-SM-IPCS.pdf”
to locate components on the
PCB.
