Hi Mark,
What's different between Nokia 1202 and HX1230? |

i dont know the difference.
i do know that there is a bug in the lib.
- open the lib with notepad
- search for : lpm ; get byte
- change lpm into elpm
- save the file
rest of the lib looks good.
when connecting lcd, best to use pins from the lower ports like porta, portb, portc the high ports like portL do not support some asm commands.

Hi Mark
I changed lpm to elpm but I still have the same problem.
I use Mrshilov "glcd-Nokia1100.lib" and I got an answer with mega 8-16-32 with this library and program. But I have a problem with Atmega2560.
for example, if I send a character for display, the display will show 16 characters in a row.
I attached the program file and library.
Thank you for your guidance |

the problem is in the LIB.
R23 is not properly saved.
The reason it works with M8 is that there the ports have a low address and CBI/SBI can be used without use of a register.
In M2560 that can work too when using ports with a low address. But you are using ports on an extended IO address.
This means CBI/SBI do not work and the compiler use R23. but it also means in the lib you need to protect R23.
Now it was protected but not properly.
I fixed it and attached the mod.
Do notice however that MCS is not responsible for third party libs.
