Need Help: Detail Support For Hitachi PC-LH3B

[bingooo]

Hello, I have a Hitachi PC-LH3B, and did some data collection base on #1063 .

Google Sheet: HITACHI PC-LH3B

Is that possiable to add Irac support for this?

Thanks.

Hello. Thank you for your data. How do you use the library with HITACHI_AC3?

Something like ...?

begin();
stateReset();
setRaw();
send();

@kmihaylov HITACHI_AC3 does not yet have detailed support. The code for it has not been added to the library.

@crankyoldgit thank you for your fast reply. I'm looking ir_Hitachi.cpp where the IRHitachiAc3 class has begin(), setRaw(), etc. Isn't these enough to send some of the codes given by @bingooo ?

[crankyoldgit]

Ah yes. It doesn't have detailed support, as in you can't tell the library to change the AC to Heat mode etc, or set the fan to Medium etc. You can however set the state code/array, as it does have enough for that.

So yes, you can set the state via setRaw() for that class, and use the send() method.
You should only need to call/use the begin() and stateReset() once. Heck, you don't even need to invoke stateReset(); actually.

See the IRsendDemo.ino code for an example.
e.g.

IRremoteESP8266/examples/IRsendDemo/IRsendDemo.ino

Lines 47 to 50 in c1a014a

	// Example Samsung A/C state captured from IRrecvDumpV2.ino
	uint8_t samsungState[kSamsungAcStateLength] = {
	0x02, 0x92, 0x0F, 0x00, 0x00, 0x00, 0xF0,
	0x01, 0xE2, 0xFE, 0x71, 0x40, 0x11, 0xF0};

&

IRremoteESP8266/examples/IRsendDemo/IRsendDemo.ino

Lines 71 to 72 in c1a014a

	Serial.println("a Samsung A/C state from IRrecvDumpV2");
	irsend.sendSamsungAC(samsungState);

The above shows you how to do it without using the IRHitachiAc3 class. i.e. via irsend.sendHitachiAc3(state_array);
Currently the class is just scaffolding for when someone writes the rest of the code/decodes the protocol fully. There really is no point using the class till that's been added.
