How can I convert from uint16_t rawData to uint8_t state?

[Damix48]

I'm trying to develop a custom component for esphome. The data from esphome are in the same format that IRrecvDumpV2 print out as uint16_t rawData but the function

IRremoteESP8266/src/ir_Fujitsu.h

Line 212 in 726b219

bool setRaw(const uint8_t newState[], const uint16_t length);

ask as input the uint8_t state (I think).
How I can convert the data?

(I tried to search how it's done in the source code but I can't figured out)

There is no direct method to convert a "RAW" message representation into a state[] for a given protocol.
You can have a look at code that does this in the tools directory. i.e. gc_decode.cpp

It does this by simulating sending the raw data, and capturing it, and then decoding it.
i.e. it prepares all the data the way IRrecv::decode() expects, and then decode() does the rest, and provides the state[] array in the result.

With a little bit more data massaging, you could directly call the specific decode you want. e.g. IRrecv::decodeFujitsuAC()

I'd strongly suggest against using "RAW" data format if you can avoid it. It's long, huge, and as you're finding out, needs to be decoded if you want to do anything with it.

Thank you!

I successfully modified the gc_decode.cpp and it worked perfectly. I generate a decode_results without using

IRremoteESP8266/tools/gc_decode.cpp

Line 98 in 726b219

IRsendTest irsend(0);

When I try the code in the pc I can decode the raw message but when I upload the same code in the esp8266 (wemos d1 mini) the state is always filled by zeros.

It seems that when the function irrecv.decode(&message) is called it does not update the decode_results message.
