Mega2560+RAMPS, D64 not usable?
I'm trying to upgrade my printer from V92.3 to V1.0.0dev, but I can't seem to take control of GPIO 64 or 40. I have searched everywhere in the code and I can't find anything assigned to that pin that can clash.
Even setting the pin as output in the "void setup()" function does not make that pin an output. Only when I comment Printer:setup() AND Commands:commandLoop() does that pin honor my request to be an output.
