Thanks Sphere..
I just googled and found a datasheet for the HD66712U controller, and while it's not a datasheet for an actual LCD, it's good enough for me.
The datasheet says it's upwardly compatible with the HD44780, and like I said in your last bunch of posts about LCDs, from reading the '712 datasheet, it looks like it 'compatible enough' with PBP's LCDOUT commands to make it work just fine without doing anything out of the ordinary. And if it turns out that I missed something that's buried in the datasheet, the register set, the commands, the timings, all look like they're 44780 compatible, therefore PBP LCDIN/LCDOUT comapatible.
Of course, this doesn't mean that your particular LCD module (probably with a master controller of some sort with probably a few slave controllers and maybe some other glue logic on board) follows the 'normal' way of doing things and it is actually completely PBP LCDOUT compatible. But I don't know what your 'chosen' LCD module is, so I can't comment on that. That's the problem with limiting yourself to a particular LCD module. If it doesn't work...Nothing works.
If you're having problems with setting something up (as you seemed to be in your last thread about LCDs), then post the problems. Quite frankly, driving this type of LCD doesn't look like brain surgery, and should be a piece of cake to get running.
