annotate Small_CPU/Src/spi.c @ 186:f11f0bf6ef2d cleanup-2
cleanup: remove obsolete code, make static, etc.
Some rather trivial cleanup things like putting demo code into
ifdefs, making functions static where possible, and against my
normal policy of hard removing unused code, commenting it out
at this point in time. Somehow, I think that this commented code
might be useful in the near future as a new pressure sensor is coming.
And finally, fixed some typo's in comment.
