OldMicroGuy:
I am using Windows with Arduino 1.0.5I am getting many errors all of the form of:
NarcoleptClass :: xx()
all followed by
error: 'PRR' was not declared in this scope.Roger
PRR is the power reduction register. The larger MCUs have more peripherals and one register isn't enough, so they have PRR0 and PRR1 instead of just PRR.
