Have the FastLED authors considered a simulation controller that would allow projects to be

Also in my mind Type 1 is an emulator and Type 2 is a simulator but I’m not sure I have the nomenclature correct.

OK I saw the FastLED reorg and this reminded me. Here is it comilng on x86. I need to add some actuall LED graphics display but you get the idea. https://github.com/garthy/FastLED/tree/FastLED3.1

i found this and it might help the “simulation” case. you still have to upload code to the actual hardware, but you dont have to carry LED strips with you.

Would be porting to MIT Processing an option? For sure not good for timing and real light effects, as a LCD computer monitor differs from LEDs, but for basic function tests. Or …the second step: controlling a real LED stripe from processing via serial, firmata. (with low refresh rate)
What is slowing down my experiments: the flashing cycle and the lack of debugging tools.

I don’t think porting to processing would be an option - processing is nominally Java based and FastLED and its libraries make fairly heavy use of C++ templates and operator overloading.

yes you are right. My idea came from processing -> arduino …but yes it is java. strange, that it was not present for me.
