Hello Community
I am using arduino with a lcd display. I use the LiquidCrystal Library to get the display to work.
Now i need to make some changes to the library, but I think arduino does not compile this library when I upload my program to arduino.
In my programm folder I found some .o files, but no .exe or .dll file.
What' s the easiest whay to get these things done?
What I exactly mean is this line(line 70 in LiquidCrystal.cpp):
command(0x28); // function set: 4 bits, 1 line, 5x8 dots
The display gets setup as a 1-line display, but I have a 2-line display and i cannot write to line two.
I simply want to edit 0x28 to another value, but when I edit this number, nothing happens.
I put a mistake to the code of LiquidCrystal.cpp to see what happens when I compile my program, but it still works.

You are correct. It does not recompile the library when you upload. You need to delete the .o file, then it will. Again - you have to manually delete the .o file to get it to recompile.
Good luck!

That comment is known to be incorrect. LCDs are known to be non-intuitive in terms of screen layout. See: http://web.alfredstate.edu/weimandn/index.html
