** ESP32 Update **
I just fixed a really (really, really) stupid bug in my ESP32 support for clockless chips (e.g., WS2812). @kriegsman and I sat down last night and spent a couple of hours tracking it down – turned out to be an integer underflow (see the git log for details). ANYWAY … if you’re using my branch of FastLED for ESP32 support please pull the latest version.

This update fixes the weird behavior associated with attaching strips of different sizes (we used this case to track down the bug)

:clap:t3: well played sir, well played

Is the plan to then submit a pull request to at support for this chip to the main project? What’s left to complete before it’s ready to be an official platform?

Just wondering if I should be buying any more esp8266s or if the esp32 stuff is stabilising enough that I should switch

Thanks Sam. Is there any way to turn the parallel output off? It crashes really badly with more than 8 strips of WS2811s.

@Jeremy_Spencer Using my current implementation you cannot have more than eight strips, even with parallel output turned off. As I think about it, though, that’s not a necessary limitation for serial output: all the strips could use the same RMT channel, I’d just need to switch the pin associated with it.

Another direction that I’d been considering is merging my code with @Yves_BAZIN 's 16-way output, which I believe uses traditional bit-banging for output.

@Sam_Guyer , that would be great, most of my projects use SPI chipsets but I’m just doing some umbrellas with twelve strips of WS2811s

@Jeremy_Spencer I’ll take a look – it should not be hard to implement. The only downside is that in many cases having a lot of strips is exactly the reason you want parallel output. But maybe in your case it has more to do with the geometry/layout of the strips.

@Sam_Guyer You’re absolutely correct.

Would it be possible to send data in parallel to 8 strips, and then send data in parallel to the next 8 (or less) strips?

So semi-parallel output…

@Jeremy_Spencer Oooh, I like that idea. I’ll try it out. I might have to buy more strips to test it out. :wink:
