Ok, I'll give it a try.
Darrel, you wouldn't happen to have a link to 8051 syntax? That would cut down on some research time and I'd be certain of looking at the proper code. I'd hate to convert all this wrong.
Should I convert to MPASM or PM? PM is supposed to be faster, but I don't know if it supports all the commands.

I've found a nice reference for 8051 here:
http://www.ece.umr.edu/computing/uni...e/tasking/asm/
Now I just have to figure if I need PM or MPASM...

This is reassuring:
"PM includes an 8051-style instruction set that is more intuitive than the Microchip mnemonics. For complete information on the PICmicro Macro Assembler, see the PM.TXT file on disk."
Crossing my fingers in hopes that I have enough information to convert this.

CALL syntax
Thank you very much folks. I'm trying to convert the assembler as plan A, I might as well get my hands dirty. I knew I had to get back into asm, I just needed a good excuse.
8051 asm has CALL (generic), ACALL (absolute) and LCALL (long).
PM asm only has CALL and LCALL.
How would you convert the absolute calls from 8051? Can you just plunk it into a generic call and consider the job done?

Hi,
If your objective is to drive the
SED1565 controller, see my previous
post for the link to a Basic Stamp
code example.
If your objective is to learn assembly,
start with LEDs and buttons and then
add an Hitachi 44780 LCD Controller.
Best regards,
Luciano

Luciano, I did. The stamp link uses the serial interface; I'd much prefer to use the parallel interface. Unless I am mistaken, that should have faster response time. The Circuit cellar example uses C, nice stuff, but nothing I can use without learning a lot of stuff. Plus, the code I have is for a 51553 demo board, exactly like the one I have on hand.
Switching to a character LCD is not an option. That would mean basing my design on an obsolete part, not interested. Figuring out how to add a touch screen would complicate matters even more. Right now I have a solid source of gLCDs with mounted TS at an excellent price.
I'm not exactly starting assembler from scratch either. I was top of my class, only problem is that I graduated in '83. I have references for both 8051 and PM assembler, most of the commands are easy to convert. I'll just have a few questions on the exception cases.
That being said, would you happen to have an idea on how to convert the absolute call?
