[FR] Single pin for LCD BTN EN1, EN2, and ENC

[Reza-v]

Is your feature request related to a problem? Please describe.

So i am designing a control board based on the stm32 blackpill and because of a limited number of pins, i've had an idea. I'm trying to combine the three control wheel pins, BTN_EN1, EN2, and ENC and connect them to a single analog pin through resistors with different resistances and have the controller sense the resistances and activate the buttons accordingly. Now i am not very adept in programming MCUs so any help is appreciated. Should i just write the conditions in the pins file and that would work? I haven't tried anything yet.

Are you looking for hardware support?

I dont think this can be done.

the encoder uses quadrature encoding

Ie there are times when both BTN_EN1 and BTN_EN2 are 0 or 1 at the same time

It's definitely possible through software it just might take up some flash space
And while there are times when both pins are high/low, that equates to another resistance value that can be picked up
