stack overflow with latest esp-idf
Hello, I just tried this with latest esp-idf 0a678ebe8c8bb78053f2a2dc4bd26124adde9122
I get repeated stack overflow errors every few seconds

How to transplant to esp32c3
RMT issue in recent ESP IDF
FYI, there's an open issue in the ESP IDF that affects my code as well as yours when built against master - basically, the RMT is no longer producing output.
I'm opening this issue so you are aware and can track it in case it turns out we need to make code changes in our respective projects as a result.
error on compilation demo
I want to use this library with IDF for making a LED indicator for our project.
I tried with demo but it fails to compile with following error

Seeing a static pattern
Hello,
Firstly, thanks for making this!
I just got the latest esp-idf and built this with default menuconfig. I see a static pattern on my 8 led strip. I tried changing the number of pixels to 2, it then lights up only two pixels with red. However, I never see any rainbow animation. Is there any special SDK setting required in menuconfig for this peripheral to work?
Timings are way off
This worked only with WS2812B devices (WS2812 failed). I looked at the signals with a logic analyzer and the values were way off. I suspect you had a typo that just happened to work given the particular ways WS2812s are timing tolerant in general - but they are very strict in other ways, which is why the older ones with slightly different specs failed.
