Things are progressing nicely. I have the display fully wired now to the Mega. It’s a spaghetti mess, but it’ll work.
I have the serial port on the Arduino working nicely for debug. I also did a fair amount of thinking with regards to data and address packetizing. It quickly became apparent that doing a bunch of digitalWrite calls for all this pins (8 data, 5 address, per character of the display) would be a nightmare.
Here is the character map for the display.
So I came up with a character array method to do this. I tested tonight with the serial port debugger to verify correct character parsing.
So far so good.
