Dave,
Just to be clear as to how I see this:
CVS custom PCB contains the BASIC ATOM PRO
LCD custom PCB contains the ATMEGA microcontroller with your code
LCD prefab device contains Samsung LSI LCD controller
You appear to be talking about the ATMEGA controller PCB below (?).
The difficulty in mounting the LCD custom PCB to the LCD prefab assembly is
that every LCD prefab aseembly has its own mounting hole dimensions. An LCD
custom PCB that fits a 2U MOTM format will be too small to fit any LCD
prefab devices larger than 16 characters. It also won't be able to fit many
of the larger 16x2 LCDs. Most of the holes won't line up or will be off the
board dimensions.
