New NEC format about irremoteesp8266

[markszabo]

Well, right now it can not send it in HEX format, since (as you said) it uses a non-standard NEC protocol. But since you have the device, you may try to write the function for it, let's say sendNEC2.
Here is the sendNEC with comments:
void IRsend::sendNEC(unsigned long data, int nbits)
{
enableIROut(38); //it will use 38 kHz to module the signal. You can probably leave it
mark(NEC_HDR_MARK); //this sends a 'mark' in the length of NEC_HDR_MARK. Mark means turning on and off the IR led on 38 kHz
space(NEC_HDR_SPACE); //this sends a 'space' in the length of NEC_HDR_SPACE. Space means keeping the led turned off for that time.
for (int i = 0; i < nbits; i++) { //sending the signal
if (data & TOPBIT) {
mark(NEC_BIT_MARK);
space(NEC_ONE_SPACE);
}
else {
mark(NEC_BIT_MARK);
space(NEC_ZERO_SPACE);
}
data <<= 1;
}
mark(NEC_BIT_MARK);
space(0); //making sure the led is turned off in the end
}

As you can see the important part is the for loop with the algorithm and the timing constants: NEC_HDR_MARK, NEC_HDR_SPACE, NEC_BIT_MARK, NEC_ONE_SPACE, NEC_BIT_MARK, NEC_ZERO_SPACE. You can find these constants in IRremoteInt.h.

If I were you I would start figuring out the differences between your code and the standard NEC code, because if it is only about the length of the signal, then it's probably enough to change the for loop above. If you manage to make it work, don't forget to issue a pull request, so I can integrate it into the library :)
