NeoPixel Stick - RGBW

Hi FolkZ,
does anyone have a working code for the NeoPixel Stick - RGBW.
I would like to use it in the web interface with the Pantilt Hat from Pimoroni.
The code of Waveform80 in the Pistreaming web interface is not working properly; the control for white does not work at all and it also only illuminates 6 LEDs in the control for ‘ALL’.

Try this example- which should turn on just the white component of GRBW or RGBW LEDs-
