Alistair Buxton 39ac48339a neopixel: Increase PULSE_LONG_TICKS to 800 for compatibility 
This timing is also known as T1H in various datasheets. Increasing it
should improve compatibility with various revisions and clones of the
WS2812 LED.

The short version is that 800 is the timing used by Adafruit's popular
NeoPixel Arduino library, and it has no problem driving my BTT RGBW kit
LEDs, while Klipper cannot drive them properly without this patch. The
real upper limit to this value is something like 5000ns so increasing
it should not cause new compatibility problems for LEDs that currently
work.

Welcome to the Klipper project!

Klipper

https://www.klipper3d.org/

The Klipper firmware controls 3d-Printers. It combines the power of a general purpose computer with one or more micro-controllers. See the features document for more information on why you should use the Klipper software.

Start by installing Klipper software.

Klipper software is Free Software. See the license or read the documentation. We depend on the generous support from our sponsors.
