4611 also non-rechargeable battery variant. I think it required READ_COUNT 6

We also need same change in C-A-P . Catena 4611 use ReadCount==6 for reading VBUS.

I just realized user have to upgrade Catena-Arduino-Platform change first which is mcci-catena/Catena-Arduino-Platform#217. |

Do we need these included everywhere? Maybe better to include these in the .c files. Not needed for API definitions as far as I can see.

Okay, I will remove these files from board.h.

Since this is a .cpp file, I don't think we need this -- it's always defined.

Is this the right sentinel variable? I think we should be using an ARDUINO_ARCH_... variable or something like that.

We have STM32L0xx and ARDUINO_STM32L0xx. But other stm32 code use STML0xx, STM32L1xx, … If you want to use ARDUINO_STM32L0xx, I can use it.

do we need this commented-out code?

do we want this print in production?

I will comment out. There is another prints and I will comment out too.

I wonder if we should have a static variable and only do an analog input for this purpose once every second or two. Spinning up the clock consumes a lot of power and time.

Okay, I will add code as suggested.
