Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Nokia 5110 is included in the firmware for PicoMite. I got it working on Picomite after some difficulties. Peter updated also the PicoMite firmware yesterday. THANKS.

In the past I used an old driver (anno 2014 by Peter) for standard Micromite (28-pin) successfully. When I recently tried to use that procedure on Micromite 5.0504, i run into difficulties.

Wondering now if there is any newer driver version for the standard MicroMite?

There was a change in one of the MM versions that required a small change to all loadable drivers. Unfortunately I've lost the source for the 5110 driver so can't make the change. The only solution would be to use an earlier version of the MM firmware if you need this display - sorry

Thanks for checking.
Got this code from 2015 working on Micromite 5.0504:

https://www.thebackshed.com/forum/ViewTopic.php?TID=10183&PID=114241#114241#114241

Initially I tried to change the ports used for rs, cdand cs for the SUB LCD.Init(rs,cd,cs,wi,ht,nr) w/o success.  Going back to the ports originally used in the program was more fruitful.

LCD.Init 17,18,16


It will still leave some room for my own programs:

> memory
Flash:
 34K (56%) Program (846 lines)
  9K (15%) 3 Embedded C Routines
  4K ( 6%) Library
 13K (23%) Free

RAM:
  4K ( 8%) 40 Variables
  0K ( 0%) General
 46K (92%) Free

I think I can manage with this for my applications. THANKS!

Noticed that I had some earlier attempts stored in library. Deleting that and this is the memory usage:
> library delete
> memory
Flash:
 34K (56%) Program (846 lines)
  9K (15%) 3 Embedded C Routines
 17K (29%) Free

RAM:
  0K ( 0%) 0 Variables
  0K ( 0%) General
 50K (100%) Free


I believe that the stuff in library prevented me from chanching the rs, cd and cs pins!!
