Method decode

src/IRReceive.hpp:563–734

* The main decode function, attempts to decode the recently receive IR signal. * The set of decoders used is determined by active definitions of the DECODE_ macros. * Results of decoding are stored in IrReceiver.decodedIRData.* like e.g. IrReceiver.decodedIRData.command. * @return false if no IR receiver data available, true if data available. */

 * @return false if no IR receiver data available, true if data available.
