Do you run your LED's directly from the Pi or via a microcontroller? 12
Yeah, Directly from the Pi (5) 42%
No, Always via a microcontroller (7) 58%
So this has always been on the back of my mind and when i originally ordered my parts i grabbed a Uno just in case and a few spare Micro Pro Leonardo's, Never used them and opted for hooking the WS2812B up directly to the GPiO - everything worked and the other parts just sat there collecting dust until last night when i fired up the Uno, They worked but i noticed the colours were way off compared to default Hyperion settings using Rpi PWM, blues were more purple etc but no big deal as i saw a section in the sketch to calibrate them.
Question is with Hardware constantly increasing on the Pi, are there any advantages over using an Ardruino or similar board rather than using GPIO/SPI, 1 of the main reasons i can see from my google searches would be my current LED Strip cannot handle PWM for the lights along with on board Audio, whether this is still the case on the Pi4 i do not know.
I will be upgrading the LEDS in the near future to the APA102's so can run them via the Pi's SPI or I could use an Ardruino, so in 2021 what is the best option or the pros and cons?
Or is that question like the amd or intel one?
