First 40 digit line is divided to 2 x 20 lines as 1st and 3rd LCD line
Second 40 position line is divided to 2x20 lines as 2nd and 4th LCD line
I mean:
(in smartie config screen):
111111$Fill(20)333333333
222222$Fill(20)444444444
looks in real like that:
111111
222222
333333333
444444444
Question - is there any way to properly use line scrolling with that LCD? Is there a way to indenpendently controll each PHYSICAL line od LCD?
P.S. Sry for my english
Its seems to be a special hd44780 created LCD.
I'm afraid that you're stuck
Last Hope:
Sometimes manufacturers are adding mode selection on their products.
Check the board for any jumpers dip switches of or soldering shorts (something like mode setting). If you find any upload a photo here.
Is it definitely a HD44780 controller? If not, what's the chip number or LCD module part number?
It might be a KS0073 (or compatible) LCD, in which case you should try the KS0073 addressing option in the LCD setup - something like "LPT1,1,a2" for the parameters. This LCD controller uses a different internal addressing scheme which swaps the lines around compared to the HD44780.
Another thing to check: Make sure you have the LCD configured as a 4x20 module in Smartie's display settings (on the "Screen" tab).
