esp-idf v4.2 rmt_set_tx_thr_intr_en() panic #13

Closed drewandre closed 4 years ago

Hi @bbulkow, thanks for this great port. Cloning this repo fresh, copying the sdkconfig.4-1 to sdkconfig, and running the example against esp-idf v4.1 results in an rmt_set_tx_thr_intr_en() panic as described on this esp-idf issue (stacktrace copied below). I understand this is an issue introduced in esp-idf v4.1 as you discussed on this other esp-idf issue.

I'm just wondering, what would you suggest users of your fork to do in this situation? It's somewhat difficult to follow where this interrupt handler issue is headed and whether it would be solved by the espressif team, or if your port needs to address it. Should we just stick to v4.0 for now? I have some ota over ble bugs that were fixed in 4.2 and I'm looking to upgrade, but this is the one issue holding me up.

Thanks again!

EDIT: What I'm mainly asking is if there is a way to use fastled with esp-idf 4.2, whether that be this library or not. I was having trouble getting arduino-esp32 to run again esp-idf 4.2 which is why I moved from using the main FastLED library to this port so I could ditch arduino-esp32 entirely. But now there's this RMT issue. So if there is another port or approach to getting fastled and esp-idf to play nicely together, I'm all ears!

 entering app main, call add leds
 set max power
create task for led blinking

Rebooting...

Closing as this was resolved by updating to the esp-idf release/v4.2 branch.
