Thanks for all your help, I understand better now. I have moved to code
like that at the bottom. It still doesn't work, but feels a lot closer.
Before I keep playing with values, I want to check I'm on the right track.
Does it look right? Specific questions:
1. I see there is a hw_init function. Should I be using that? I put the
logic into fe_attach because there was already card-specific logic in
there. But this feels like hw initialisation.
2. Should I set the control to input or output? I'm assuming input = 1.
3. Would pin 15 be numbered from the left or right - is it 0x4, or 0x2000?
Thanks,
Paul
