How many Potentiometers / Buttons?

#1

Hi Forum,

first post :wink:
so - hi to all and please excuse if i somehow oversee something regarding the nettiquette here...

while looking through:

and having an axoloti board on its way, i wanted to be sure that i can connect something like:

  • 5 buttons to the Digital INs (PB6/7/8/9)
  • 15 Potentiometers to the Analog INs

would that be correct?
and, what about connecting encoders?
would it be feasible to connect some LEDs to get feedback?
can i switch patches from within one of the buttons?
or "hard" wire some patches to the 5 buttons?

thank you so much for helping me out :sweat_smile:

cheers
daniel

5 buttons / 15 potentiometers should be about right.

Haven't used encoders yet myself with Axoloti, but they will probably use 2 ports for the angle and one extra if you use the integrated button.

LEDs for feedback is possible on the same port if you use a toggle switch.

Switching patches with a button should work.

wow - that answer came fast.
thank you for this information.
at the moment i have momentary buttons in mind.
i think there are a bunch of questions in the pipeline as soon as the board is here.
good to know theres help :smile:

About using LEDs in combination with buttons, see last part of this thread. I can confirm that using a latching pushbutton in combination with a LED only uses up one GPIO. But I concluded that using a simple two position toggle switch is simpler and gives you the same visual feedback.
