I have been reading all over this site for about a week now and everytime I think I get it I read something that makes me think I don't get it again ::) Basically, I know it depends on software running in the PIC but with MotorFaders it seems to be pretty universal... 8 per core... but what else can be done on that core? Can I still have encoders? I think I know that I can still run 64 buttons and those are done via the DIN so I would think encoders fall under that also... how many can I hook up? I would just like to see a clear consice example of what can be hooked up to a core... it always says "up to 64 this, up to 64 that, up to 128 leds..." but I can never tell if they mean AND this and AND that... or OR this and OR that. Single core can drive: X - MF AND X - encoders AND X - Pots AND X - buttons AND X - LEDS I know the answer to some would be ZERO but that is what I would like to know.... Sorry if this seems dense and redundant (I have a tendancy to do that) but this would end a lot of the questions I have been reading pages and pages trying to figure out ;) Thanks guys and thanks for a kick ass PIC!
