Detailed descriptions of the LED Strip Configuration dialog.
This documentation aims to explain all of the settings in the LED Strip Configuration dialog, so you can make the most use of them.
DMA Channel and PWM channel will remain available for editing using config.yaml, just in case you need to change this. You probably won't.

Setting
Value Type
Explanation
Strip Type
Selection
The type of strip you have connected, for a complete list see supported hardware
Max Brightness
Percentage
The maximum brightness the strip should reach in any effect.
Number of LEDs
Number
GPIO Pin
Number
The pin that the LEDs are connected to. This should be BCM GPIO 10 for normal operation, other pins are available when OctoPrint is run as root and can use PWM - though this is explicitly not recommended for security reasons.
Frequency
Number
Frequency to drive the LEDs at. This should be 800 000 in normal use, some older strips may require different values.
DMA Channel
Number
(To be removed from the UI in a future version)
Do not change the DMA channel if you do not know what you are doing.
This should be 10 in normal use, other values can cause severe problems.
Invert Pin output
Checkbox
Invert the signal from the Raspberry Pi. Useful if your setup uses a level shifter that inverts the signal, it can be inverted again to make it the right way around in the end.
PWM Channel
Number
(To be removed from the UI in a future version)
Internal PWM Channel. Irrelevant to the plugin since it uses SPI in most cases.
I hope this one is obvious enough
