No, this is not how copyright works. What you want to learn from looking at their code is not the part that is copyrighted, but the facts, like which registers needs to be set to what value at which time and sequence. Whoever wrote the driver copied those facts out of a datasheet as well. > > -- > Dmitrij D. Czarkoff >
