digital inputs used as Interupts in dual mode

I know that some digital inputs can be used as interrupts, DI-2 can they be used in a dual mode ..? that is held @ 2.5v by a 2 resistor voltage divider and a button across each resistor. would the interrupt falling and interrupt rising still work ? +5v ---------- < | R > \ S/w < | DI------------- < ...

Re: Arduino WiFI and LCD&Keymade not working

"hello world" , works but the "forms " with the menus does not ,,

LCD.h library has issues , think its looking at the default pins, and i'm not sure how to tell it to look at the pins i've moved them to.

LiquidCrystal works but LCD does not,

Re: EtherMega Unknown Device

I have also had this issue , but this occurred after using it for about a week of normal use with no issues . Also noted at the time that the PWR led was also unlit, was powered by USB . So thinking it was a power supply issue, tried powering from 12V input, No luck. Since the board was under warran...
