Hello all! I'm not sure if this is the correct list to post this to, but I believe I've found a mistake in tos/chips/cc2420.h on line 163. CC2420_SRXENC = 0x0d, should actually be CC2420_STXENC = 0x0d, as defined at the bottom page 60 of the CC2420 radio datasheet. I figured I would post it here to document it. Cheers.
