@lupyuen Impressive. I have No Idea how I'd look at a stream of bits and deduce that clock recovery (ala Manchester) is missing and know to add it like he does in https://gitlab.com/oliv4945/rika-temperature-sensor-encoding/-/blob/main/rika_payload_helpers.h#L13. That's experience at work!

Instructional read with a bonus link to a RP2040 analyzer https://github.com/gusmanb/logicanalyzer, but I think I'll save my pennies for Sipeed's promised Bl808 (TH1520?) analyzer. Because, you know, #Team_RISC-V! 🙂
