Assembler: please kick me in the right direction

[Demon]

Hi,

I have assembler code that I'd like to integrate into my PIC Basic Pro application. The only problem is that I haven't touched assembler since 1980, so I'm very rusty (make that totally ignorant by now).

I'd appreciate any help in finding a tutorial to better understand this stuff. One problem I have right now is how to identify the pins. I also foresee compatibility problems, no idea what version of assembler this is in.

This is the code for an Optrex 51553 graphic LCD. I also have on hand the 2 include files at the end; the image and font definition.

Here's the schematic that goes with the code:

Hi Robert,

That's going to be hard. The program is written for an 8051 type processor.

Many of the 8051 directives are similar to the PIC ones, but you'll have to re-write the whole program.

By the tone of your reply, I take it that it's more than just correcting the command syntax and that the actual coding is affected as well...

Darn, this was the best example I had to manage an Optrex 51553 gLCD. I've scoured Google and found nothing for the SED1565 controller. I've checked out the links posted in here fo gLCDs, but they are all for other types of controllers.

That really sucks 'cause this LCD is really cool; white font over a blue backgound, with backlighting and touch screen. That, and the fact I have 5 on hand and just finally managed to assemble a PCB to receive the 0.5mm pitch flexible film connector.

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:

Now I just have to figure if I need PM or MPASM...
