@ikeWren @wyatt caixiansomethingorother is ... documented; not well documented, its documented in the openshock docs which is to say its documented like shit, ie wrong, but they have a starting point. I used Universal Radio Hacker to RE it in addition to their weaksauce doc, which is why and when I obtained my first SDR (which then spiraled). Also their code is ass and I don't trust it. I don't trust my code, either, it's not finished and I wrote it before I got up to my current level of C competence and it's not packaged and prettied up for other people to use as an end user but I know for a fact that the RMT state machine is correct (also its ESP-IDF and I know now that I really dislike ESP-IDF) and better the beast you know. The RW mod I wrote to connect it up works but like the ESP firmware never left hacky prototype stage.
