IR driver on BL602

[rnrobles]

Describe the bug When trying to use the IR module as a receiver, apparently it does not have that driver enabled with the BL602 chip, is it possible to add it?

Firmware:

• Version 1.17.244
• Device ZJ-bwcd-ir-vc MagicHome
• Chip/model: BL602
• Device config: { "vendor": "Tuya", "bDetailed": "0", "name": "Full Device Name Here", "model": "enter short model name here", "chip": "BL602", "board": "TODO", "flags": "1024", "keywords": [ "TODO", "TODO", "TODO" ], "pins": { "3": "PWM;1", "4": "PWM;0", "12": "IRRecv;1", "21": "PWM;2" }, "command": "", "image": "https://obrazki.elektroda.pl/YOUR_IMAGE.jpg", "wiki": "https://www.elektroda.com/rtvforum/topic_YOUR_TOPIC.html" }

IR interrupt is not implemented on BL602, that would require some programming work, do you know C?

a few years ago I used a bit with arduino, if you guide me maybe I could help with that part

Note that the BL602 has a built-in IR remote HW accelerator, but it's buffer is only large enough to receive commands from "simple" remotes, eg for TV's, etc, that only send 4 bytes of data. More complex remotes, eg those used by AC systems, can send 12 bytes, which will not fit into the HW accelerator buffer.

I have had good success reading the longer signals by using the IR receiver as a regular GPIO pin that triggers an interrupt and then just tight loop reading the pin until all the data has been received.
