Hi,
regarding the DGND and AGND i already understood that i have to connect them both together.
But i do not understand when to use 3v3 Digital (pin 38) or 3v3 Analog (pin 21) in a cirquit (for instance on connecting LED, Poti, or more sophisticated things like bus connections). Is there a simple rule that helps me to understand when to use which ?
Georg
hmmhm, support is, as i supposed, non existent. switching to arduino, raspberry and teensy. bye

I don’t expect Electro-Smith to read all posts on their community forum, read all messages on discord etc. If you need an answer, use the above form.
Here’s a couple of links on digital/analog ground:

I see. Thank you for this information and the links. I think these should solve my question.
