Rotary encoder to control GM slider

[richbass]

Hi all,

I'm about to start wiring up a rotary encoder to gpio pins for control of the GM slider; a simple direct overall brightness control.

Is this possible? (Seems to be from reading other posts)

Has anyone already done this that could share some tips or code? (I've searched here and found details on gpio control of relays plus the thread about discoHat, but nothing specific for what I'm about to implement).

Thanks

ATM it is not possible since GPIOs are only handled for high/low states.
Encoding (and I guess PWM) would be possible but requires some rework.

Gotcha. Thanks
