Decoding signals from IR remote controls with LabVIEW

[Max_67]

Yeah, I think your analysis is correct.

My knowledge of the subject is still rather limited; over the next few days I’ll try to work out how other protocols can be decoded in order to have a clearer overall picture.
I'll keep the thread updated as I have some new findings.

Tests done with the remote of my main TV, which is a Philips (android TV).

The IR protocol seems to be the RC6 which relies on the Manchester encoding.

Data bits are encoded with transitions from LOW to HIGH (1) and HIGH to LOW (0).

But I was reading that it can also be the opposite... as always there are many versions out there...

Anyway, the little system with LabVIEW seems to behave fine also with this.

For now I only focused on the last 16 bits, which are the Address byte and the Command byte.

Before there is a sort of header with control fields.

Test done with the "OK" button of the remote which is 005Ch.
