all lights break down after about one minute

[IcyFeather233]

Hello, I really apreciate the ws2812fx, however I meet a problem recently. I want to make a new shop sign and I use ws2812fx to control my ws2812, but I meet 2 problems.

1. When I set the light to certain static color in segments first, and then I want to set them all in rainbow, I don't know how to make it, it always turned out that only one of the segments is in rainbow status.
2. When I use mqtt to control the status, the ws2812 will break down after running normally for a minute, first it will stop the animation, then all lights turn down and I lose the control, after a minute I can restart it and continue to control.

There are a couple problems with your sketch.

1) you should initialize the segments in the setup() function

  ws2812fx.setSegment(0,   0,  55, FX_MODE_STATIC, 0x007BFF, 1000, NO_OPTIONS);
  ws2812fx.setSegment(1,  56, 100, FX_MODE_STATIC, 0x007BFF, 1000, NO_OPTIONS);
  ws2812fx.setSegment(2, 101, 162, FX_MODE_STATIC, 0x007BFF, 1000, NO_OPTIONS);
  ws2812fx.setSegment(3, 163, 227, FX_MODE_STATIC, 0x007BFF, 1000, NO_OPTIONS);
  ws2812fx.setSegment(4, 228, 253, FX_MODE_STATIC, 0x007BFF, 1000, NO_OPTIONS);
  ws2812fx.setSegment(5, 254, 289, FX_MODE_STATIC, 0x007BFF, 1000, NO_OPTIONS);
  ws2812fx.setSegment(6, 290, 317, FX_MODE_STATIC, 0x007BFF, 1000, NO_OPTIONS);
  ws2812fx.setSegment(7, 318, 352, FX_MODE_STATIC, 0x007BFF, 1000, NO_OPTIONS);

2) when you change the color or mode of a segment, you should be using the setColor() and setMode() functions that take a segment index as a parameter.

ws2812fx.setColor(idx, colorhex); // idx is the segment index

Otherwise you'll only be changing segment 0.
