NeoPixel On-With-Power

Post by AlexMaghen »

I *think* I'm asking for the impossible. But lemme try:

I would love to connect a NeoPixel to my RPi such that when the NeoPixel first gets power (no control signal, just power) it turns on to a certain color. Then, once the system is fully booted and the software is running, my software can change the color. But the point is to have the NeoPixel default to a certain color and "on" when it receives power.

Adafruit Clause, that's what I want for Xmas... though I'm Jewish so...

Thanks!

Alex

I'm afraid the NeoPixels will do nothing without their colour being set via the data signal. Sometimes they will come up in a random color, but you can't set them to power on in a certain color.
