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.
