why does my lcdsetup routine: stop my serial int from triggering?.
is there something else i can use here that wont bugger the serial interupt?
other then just manually doing each letter of the welcome screen on lcd?
i have am running this in a simulator with a debugger when i skip my lcdsetup the serial int triggers like it is meant too but wont when i enable the lcd routine.
