STM32F405 & NeoPixel

by ramsh on Mon Sep 07, 2020 6:29 pm

Hi,

Is it possible to use the NeoPixel Stick - 8 x 5050 RGB LED with Integrated Drivers with the STM32F405?

Thank you in advance,
Ram

i'm a bit confused and need assistant, looking at the Adafruit Feather STM32F405 Express it states :
Built in NeoPixel indicator


however in Python & CircuitPython page it says:
Of single boards computers, only Raspberry Pi computers have NeoPixel support at this time.


look forward to your assistant!
Thx again.

NeoPixels are supported with CircuitPython on the STM32F405 feather.

The feather isn't considered a "single board computer" so the statement about Raspberry Pi does not apply to it. It only applies to regular Python in Linux.

That's great news!!

My board runs version:
Code: Select all | TOGGLE FULL SIZE
Adafruit CircuitPython 5.3.1 on 2020-07-13; Feather STM32F405 Express with STM32F405RG


I looked at the Bundle Version 6.x and couldn't find the "Adafruit CircuitPython NeoPixel" as a lib (only pip3 installation), clearly, I miss something, can you pls point me to the files I need to save in the Feather's lib folder to be used with "import neopixel"?

once again, great news, i really don't want to use C anymore :)


please ignore the post, for some reason i missed the files... my bad!

    neopixel.mpy
    adafruit_pypixelbuf.mpy

Cheers,
Ram
