I may have a stupid question about changing the Configuration.h for the Display which chan be connected to the RAMPS.
My overall config is running fine and I have a spare display.
It is that LCD Graphic Smart Display Screen Controller Module. 2 Lines of display characters.
It is luminated but nothing will be displayed.
I learned the other day, that I must change the Configuration.h and uncomment some lines.
Like that one below.
// RepRapDiscount Smart Controller.
// Note: Usually sold with a white PCB.
After hitting the Upload button on the arduino IDE, the compiling porcess starts but nothing changes in the behaviour of the dicplay.
My question is now, do I need to tell the compiler that I have changes the .h file? USually not, because that would be the first compiler in 30 years of software development I am doing where this would be the case.
Or do I adapt something in the makefile?
So where can I search?
Any answers are welcome!
