The schematic has two LEDs hooked up to B on BDBUS6 & 7. Would it be difficult
to make those blink?
BDBUS0 & 1 are apparently IRQs, those are probably more important to me.
A few other things are hooked up as well, though if I read the SX1211 data
sheet correctly, those don't really interest me at all.
So far, I have this: http://pastebin.com/FsRsDaXB
It compiles without error. It runs without segfaulting. But the value I read
back from the register does not seem to be the value I put into it. In fact,
reading it twice, I get back a different value each time, usually 0x00, 0xfa
and 0x8a.
That's better than I was doing yesterday though.
