I leave the function to generate giant characters on a 128x64 GLCD.

Code:

I presume you are aware that the Nokia 5110 IS a graphics screen?.
Hi N,
Thanks for reminding me, that the 5110 is a graphics screen, I'm used to it as only text, though.
I was thinking of this type:

No text on a 5110 - it's graphics only, and you have to draw the text yourself, including providing the font

The TFT screens are a lot more complicated, and use much more memory - you've also got zero hope of a screen buffer, which is what you usually use on the 5110.
 
Hi N,
Yes, back around 2017 E wrote me CODE for this very thing, so somehwere here you'll find it all.
