STM32 Bits: Neopixels!

[@patrickmonnier2193]

Data line of the WS2812 has an high level ( logic level 1) at 0.7vdd ( 3,5V for vdd 5V) so you can get erratic behavior with some chip (even not working at all), so you should use a level shifter. The simplest way ( at least one way ) is to configure the output as open drain (without internal pull-up) and add an external pull-up connected to the 5V, something like 2k2.

The library is nowhere to be found in the library manager

FastLED and adafruit neopixel might work now with the base STM 32 stuff. It's been a few years

@@CalebMarting im trying both right now, ill let you know

Do you use external power supply or only 5V line on plate?

[@CalebMarting]

I used the 5v line that's supplied from the USB, but as long as the grounds are common you can use an external one
