smart GPU library not compatible with arduino due..?

hii, Right now i am working on integrating a smart GPU with an arduino due, but it's not working, the library had originally been built to be used with uno but i am trying it on due, can anybody suggest if there are any compatible issues due to which it's not working or else i should look for some other problem, for ex- one issue that i found out was normal arduinos use analogReference() while for due its eAnalogReference(). took a lot of time to just figure this thing out, as it has not been mentioned anywhere about this difference, saw some sample codes for due n then realised it.

here's the smart GPU's library for ref-

PS- i am rather a newbie when it comes to arduino n all such technical stuff(don't have much idea about the serial communication either).
