TSC Groups on L432KC

Hey there,

I'm just getting started with touch sensing on the STM32L432KC, therefore I wondered about the following: I can just see "Group 2" in System Core > TSC (See picture). "Group 2" implicates, that there is a "Group 1".

Is there also a "Group 1", which I can't see because of some missconfiguration?

Thanks for the replies!

    Hello Arndt,

    On this MCU you only have 1 TSC group named group 2.
    On larger MCUs like STM32L412 for example you have 2 TSC groups and it happens that on PB4 and PB5 it is named TSC group 2

    So to keep a coherent naming convention we decided to keep the same group name across all the series.
    That's why you see group 2 there but in reality you only have 1 group on your MCU

    Hello Stassen,

    Thank you for your fast reply! The naming convention makes sense, even if it is not really logic to start counting by 2. But that explains everything I need to know.

    Kind regards,

    Arndt
