Using Nokia LCD

[mister_e]

Thanks Fratello,
Yup, I'm aware of that, But I would prefer the CE option, since it's better to initialise the LCD right after a hardware reset. Basically you can set the CE pin to ground without problem. Now if you really run out of I/O, you could use a R/C network on the RES pin, and do the initialisation. Another thing, if you run your unit and want to go in Sleep mode... you can still re-initialise the display after the Sleep. Not sure if you can do it properly with the RES pin always high.. However, I haven't messed too much with this too much.

If you want to save an I/O, set the RES pin to Ground and use the following define
DEFINE GLCD_OVERRIDE_CE

This will remove the CE High/Low at compile time.

Thanks Rujic. This should work

The next and final version Include the Variable/constant to HEx/Bin/Dec conversion routine, improvement for custom, character/custom screen and... that's all. After that, it will be to the end user to make his own homework

Mister_e: I had very long time since last read this thread!
I see that ther has been great project with NOKIA LCD stuf!!!

Excellent work you've done my friend!

If ever I need to use nokia lcd ,in the future, your routine will certainly be my first option!!!

Haha thanks Bitmaniac!
I don't know how much future there is in those Nokia LCD right now, seems the deal is no longer the deal some had couple of years ago, however it's been a good and funny project. Learnt a lot from it. Still polishing the latest version for PBP 2.60, and I guess I could have it easier to use for PBP3 but not sure yet.

Side note, for the Proteus/Isis user, one of my friend found a Model for that. I haven't used it myself because... I don't use Proteus.

OK, it seems it doesnt simulate all Nokia features like Contrast, Inverse Video and couple of other, but It looks workable. Here's the link for those interested.

What I've been told about the installation: You unpack the .zip file and copy the files located in Models and Library folder of this zip archive to Proteus/Isis Models and Library folder. Period... and it should work. My friend use Version 7.8 on Win 7 , not sure if this is the latest version or not... however...

@ Steve,
Perhaps one can convert it to work on a modern TFT type NOKIA lcd display, as 3310 displays may not be available in future.

Sure enough, it's a huge core for ANY Glcd. Sure they will be available for some times... but not those <= 2$
