Re: [lcd4linux] Wire a LCD HD44780 with GPIO from Raspberry Pi - How to define the Port information?

[Baran A. <bar...@go...>]

Maybe there should be a way to modify the source code of a driver...
Does anybody know, how big would be the effort to write a new driver and
which area of the source code, needs to be changed?

Thank you.


best regards

Baran
