Minimized Neopixel library?

Post by westfw »

Is there by chance a sort of minimal neopixel library for controlling the single neopixels "LED_BUILTIN" on boards like the QT Py?

What programming language?

There's the Arduino library:
https://github.com/adafruit/Adafruit_NeoPixel

and the CircuitPython library:
https://github.com/adafruit/Adafruit_Ci ... n_NeoPixel

but nothing like a specialized minimal library. Are things not working using those libraries on the QT Py?

For Arduino.
The Neopixel library works fine, It just offends my sense of "object code minimalism"
(I suppose that at less than 1k of code (the way I'm using it), out of the 248k available, I shouldn't really complain. But old habits die hard.)

Search around. There's probably something out there. Just nothing hosted in the Adafruit library repos.

Maybe this?
https://github.com/cpldcpu/light_ws2812

And searching for those more generic terms like "WS2812" might help also in finding other options.

Yeah; thanks for that pointer.
I found this PR for the adafruit SAMD core: https://github.com/adafruit/ArduinoCore-samd/pull/223
And the UF2 bootload source has this (rather buried in "utils": https://github.com/microsoft/uf2-samdx1 ... rc/utils.c
