In order to get some reasonable lighting, I was searching for an LED light of simple white leds. I ordered one I thought qualified for that, but it turned out to be a ring of 8 WS2812 leds. So now I must somehow make these glow white with software. I wouldn’t want to add an arduino or alike to the setup just in order to control the LEDs.
However it seems to be not that simple to do this with OpenMV. I have seen some examples in some forums, but these approaches didn’t really seem to work:
- NEOPIXEL AS A LED RING LIGHT - #5 by jpilarski (Didn’t seem to work)
- micropython neopixel module not working in openmv · Issue #338 · openmv/openmv · GitHub (When trying out the code I get “strh expects an integer” errors, replacing stm.GPIO_BSRRL and stm.GPIO_BSRRH with stm.GPIO_BSRR obviously made it compile, but not make it work.
I would be super happy if someone could help me with this … I’ve connected the data channel to pin 7
