with ESP12 instead of Raspberry, but don't work.
It work if I use two different power supply, for LED strip and for ESP12 an only if connect PCA9865 V+ pin.
It work but flick with no brightness set.
I used IRLB8721PBF mosfet, if use arduino board and fade all is OK.
Do someone know a working dimmer with ESP12?
Thanks a lot
Alberto
