LED Strip Configuration

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.

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

I hope this one is obvious enough 🙂

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.

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.
