Add option "analog no pullup" in webapp

Hi farmbot team,
(I use the old arduno/Ramps electronics.)
As discussed in other threads, the pullup resistors on analog inputs do not make much sense and tend to make trouble with new tools (capacitive soil moisture, distance, etc.). In the webapp under “control/sensors” there is already the option “digital”, “analog”.
I suggest introducing “analog no pullup”. There is a G Code Command to switch off pullups in arduino firmware. Therefore this feature would be implemented straight forward, I think. It would solve compiling custom arduino firmware to get rid of the pullup temporariliy, as suggested in another thread.

Greetings and thanks for the great work,
Georg (qurzschluss)


I encountered this problem a few years ago and agreed to the proposal, thanks!

Hi @qurzschluss this seems like a reasonable feature request. I have added it to our issue tracker:

Please note that it may be a while before this feature is implemented, as we’re having a hectic 2020.


In the meantime, there is also a Set Pin IO Mode Farmware available to change pin pullup behavior from a sequence or the web app.

Hi Gabriel, hi RickCarlino, thank you for the double good news. Very useful Farmware-workaround. Georg (qurzschluss)
