I confirm, everything works! But what have you changed? š® I saw what was changed, but how? š

One would be to create the nodes and clone the one of the library, but in this case combine the project with the library but editing the files manually.
Sometimes I use two or three XOD instances and Notepad ++

It looks like cesars has found a solution to the original issue but Iām taking some time now to review that whole project as there are some additional things Iād like to improve, e.g. the button-presses that are detected from those integrated LCD-boards on an analog pin via analogRead sometimes seem unreliable, now that XOD allows easy inclusion of Arduino libraries in C+Ā±defined patch nodes there is probably a better library available for that task. Or I could write a lil state-machine that should improve it.
At minimum the patch node for the input that reads the analog pin for the button-voltages shouldnāt have āLoopā as an input for its clock as I have it in the example, it should be clocked at a more reasonable frequency like 50 or 100Hz or something. But the simplistic voltage-comparator way I have it written would still allow the possibility of picking up invalid transitional-states from say switch contact bounce even at a lower sampling frequency.

There is a very complete Marco Colli library but my head canāt understand it haha.

Nice! I will definitely look it over. My XOD-implementation is more simplistic and itās rather inflexible, a bit of a āproof of concept.ā
The ideal would be something more resembling a model-view controller and state-machine sort of thing to define menu transitions and effects of inputs, with more flexibility on what kind of inputs a given sub-menu could accept, what data it could display, and hand off to the āback-endā model.
How to translate that to something appropriate for XOD that could be expressed with patch node interconnections and have low storage overhead would take some thought š
For a limited subset of inputs (one XOD ānumberā-type from a pot or something) the way Iāve done it is amenable to a model-view type of arrangement but essentially you have to build the āmodelā in XOD with storage and feedback nodes yourself; making the menu nodes abstract and having several overloads that could accept different types of data might be a useful improvement.
