- Added IR send fuctionality (IRSND).
- Use
TIMER2_COMPB_vect
to be compatible with tone() library. - No longer required to call initPCIInterrupt() manually if IRMP_ENABLE_PIN_CHANGE_INTERRUPT is set.
- Separated code for timer to IRTimer.cpp.h.
- Separated code for Pin change interrupt to irmpPinChangeInterrupt.cpp.h.
- Fixed wrong pin numbers for BluePill.
