Hello, I have connected the WS2801 as follows: 5V to power supply CI to Pin23 DI at Pin19 GND to Pin5 and -V of power supply unit

With the Node I have entered only the number of the LED's.

The whole then controlled by an Inject block. At String I entered [10, 10, 10] and at Topic "fill". But nothing happens.

Who can say what I do wrong?

Thanks

The type should be either JSON or Buffer, not string.
