stm32h7b3i-dk : Is it possible to use touchgfx / LCD and analog audio input at the same time

Hi,

I am not able to understand the pin mapping in stm32h7b3i-dk (default pin mapping). I wont be using stmod+ but I need to use analog audio input (3.5mm Audio jack in) . By using the default set of pin mapping is it possible to use TouchGFX monitor and analog audio input without pin conflict? I tried to check this out myself my I am slightly confused about this.

 

Thank you in advance!

    Hello,

    The only ressource I can see from the board's schematic is the I2C4:

    The Audio codec:

    The LCD:

    But since it's an I2C I don't think it's an issue. The mux is managed by I2C device address.
