Microphone Examples Not Working - I2C_BUS: I2C bus has been already created
Posted: Wed Apr 19, 2023 3:02 am
Hi,
I'm trying to use the ADF examples that come in the ADF repository, namely the pipeline sonic example.
Environment details:
Board: LyraT-Mini V1.2
OS: Windows
IDF version: 4.4
ADF version 2.4
When this line runs
in the app_main function within sonic_example.c then the montior produces the following warning:
I think that all the warnings tie back to the first warning about the I2C bus. Can anyone please tell me what the issue is?
I have tried other examples using the microphone and they produce the same error. Examples not using the microphone such as 'Check board buttons' and 'CLI' work perfectly.
Thanks!
