Excellent! Is there a default implementation of \_readRegularADCVoltage that calls analogRead on other CPUs? That would eliminate a lot of hassle using it in classes like [LinearHall](https://github.com/simplefoc/Arduino-FOC-drivers/blob/master/src/encoders/linearhall/LinearHall.cpp).

Hey!
No I did not implement it as a unified hardware specific abstraction for the moment.
Honestly, I also wanted to see how people will use it and if it’s gonna be good enough.
We do not even use it for inline sensing on stm32.
But we might do it for the next release!

I’ve encountered another minor issue with \_readRegularADCVoltage, which is that it takes a pin name rather than ADC channel, so it can’t be used to read STM32G431’s internal temperature sensor on ADC1\_IN16. Perhaps we could add a secret bitfield in the upper bits or a second argument specifying which ADC to read, in which case the first argument is interpreted as channel number?

Ah!
Because the corresponding pin name is not declared?
Not even with the alternatives?
Yeah, it makes perfect sense to make an alternative function definition that takes the ADC index and the channel.

It’s an internally connected channel, so there is no pin for it. It’s possible there could be a dummy pin in the library code that maps to ADC1\_IN16, but I don’t see anything in PeripheralPins.c for it. I also tried searching how to get the temperature with analogRead since that also takes pin names, but all results are HAL code.
The opamps also have internal channels that allow reading their output without occupying a physical pin.
