Samsung Graphical LCD and LCD Smartie

Hi,

I've managed to hook up a Samsung graphic LCD (KS0108 - 128x64) to a USB PIC (18F2550) and built a matrix orbital compatible driver. Quite cool I think. I've also got this running using a standard text based LCD display at 20x4 lines.

Problem is the Samsung can handle 21 characters across by 8 lines deep. Is there an easy way to fool LCD smartie so I can use 20x8 or 21x8 ?

Cheers,

Andy

Not easy at all.

But you can fool the display. Just define smartie as 4x40 (160chars).
Your display can split one smartie row in 2 display rows

not for your display, but you got it working for 4x20.

Just implement 8 rows x 21 columns and use this: http://czi.uni.cc/LCDSmartie/LCDSmartie_6.0.0-b.rar
It can drive a 8x21 lcd.
I did this version for my 16x40 lcd but sadly, I lost the sourcecode in a HDD crash.
I can't remember if matrix.dll will allow you to use 8 rows but graphic.dll will surely do (also graphic.dll has all 256 characters definable if you implement it in your PIC).
