WebNov 2, 2024 · NeoPixels Revealed: Going NSA on pixel-to-pixel conversations The short answer is that the first NeoPixel will “reshape” the oversized 1-bit by shrinking it down to a normal-sized 1-bit. This leaves a low gap after the bit. If this gap is longer than ~6,000ns, it will become a reset pulse (TLL) to the next pixel in the string. WebGot NeoPixels?
