Nokia lcd include , small footprint to suit pic16's

[richard]

yes probably, but here is a new version with double size chr capability and mssp and font unpacking in asm [like in my ks0108 code]

its not been texted on a pic18 , but its blisteringly fast on the 16f1847, and will fill screen fully

thanks go to blll [wjsmarine] for donation of hardware for this project, enjoy

That's impressive, Richard.

Can you explain how your font table works and how you derived those values in each column please? What limits the size of the table one can create?

I'd like to learn from it and maybe if I can get my head around the process find a way to smooth out the double size characters (particularly 0-9, the degree symbol and C) - I'm guessing you are working your magic to achieve double size by math so it probably means making a larger table to accommodate these.

An indication of smooth characters is shown in the pic attached, made with the previous lookup table style, which consumed 4 normal sized chars' area per big one and 2 lines (as does yours) and also noting the degree C was formed as one big character. Apologies for the blurry image, not helped with the scratchy plastic over the LCD to protect the glass...

Thanks for your patience and help.

Regards,
Bill

I replace the _ chr with @ dw 642 , 9266 ,72 in my fonts to get a deg C chr

achieve double size by math so it probably means making a larger table to accommodate these

correct , I know of no realistic way to smooth the result , it has been tried.
table size is only limited by the memory available.
if you create a large font say 14x10 for digits it would not be an unreasonable size, but would need its own routines to unpack and display
if you plot my font on graph paper its pretty obvious how it works, the pic 18 version is easier to disassemble
