  • Can someone clarify the use of both interrupts? Since there's an ATmega328 uC piggy-backed on this display it's not clear to me if the interrupts used belong to the onboard ATmega328 or to the Arduino to which this display is wired.

    If it's the host Arduino's two interrupts, is this a limitation of the SoftwareSerial library used to communicate with the display or something else?

    I was trying to write to the display from within an interrupt service routine and doing so locks up the host Arduino so I'm guessing it's the host Arduino's two interrupts. If this is the case, it's too bad the compiler preprocessor doesn't catch the overallocation of interrupts.

No public wish lists :(
