NeoPixelBus strip = NeoPixelBus(pixelCount, 4, NEO_GRB);
NeoPixelBus<NeoGrbFeature, Neo800KbpsMethod> strip(pixelCount);
Confused.Are you just using the shield, or is it plugged onto e.g. an Uno.The ESP on that shield seems only connected to the TX,RX pins.Leo..
So you're saying those 2 groups of pins marked D + G (in my diagram I'm using D and G from pin #13) aren't connected to anything?
