Tool for controlling DMX video lighting using a Loupedeck as a UI controller.
My desktop video conferencing setup include several video lights which are all controlled via DMX, so I can control brightness and color temperature. I have lights above my monitor on the left side, centered above the camera, and on the right side, plus an overhead light and a background light.
Originally, I was using a cheap hardware DMX controller for this with a bunch of sliders, but I ended up writing this instead. I have a Raspberry Pi with a cheap USB DMX controller, and I'm using a Loupedeck (I've used both a Loupedeck Live and a Loupedeck CT) for the UI.
This repository contains the code that makes the whole thing work. It knows about my lights and gives me a simple interface for changing brightness and color, plus turning the lights all off or on to a specific default.
This is (currently) very specific to my needs, but could be used as an example for how to use my Loupedeck library, and it'd be easy enough to adapt if anyone wants to build anything similar for themselves.

Functions ¶
func ColorTempButton ¶
func ColorTempButton(l *loupedeck.Loupedeck, w *loupedeck.WatchedInt, min, max int, button loupedeck.TouchButton) *loupedeck.MultiButton
ColorTempButton creates a Loupedeck button for managing color temperatures for a specified light, ranging between 'min' and 'max' degrees K.
Types ¶
type AeosLight ¶
type AeosLight struct {
// contains filtered or unexported fields
}
AeosLight controls a Rotolight Aeos light
func NewAeosLight ¶
func NewAeosLight(dmx *udmx.UDMXDevice, dmxid uint16) *AeosLight
NewAeosLight creates a new AeosLight object.
func (*AeosLight) MaxColorTemp ¶
MaxColorTemp returns the maximum color temperature of this light
func (*AeosLight) MinColorTemp ¶
MinColorTemp returns the minimum color temperature of this light
func (*AeosLight) SetBrightness ¶
SetBrightness sets the brightness of the light on a range from 0 to 100%.
func (*AeosLight) SetColorTemp ¶
SetColorTemp sets the color temperature of the light, in degrees K
type LightController ¶
type LightController struct {
Loupedeck *loupedeck.Loupedeck
Position LoupedeckArea
DialButtonID int
X, Y int
Brightness *loupedeck.WatchedInt
ColorTemp *loupedeck.WatchedInt
Lights []Light
// contains filtered or unexported fields
}
LightController is a controller for one or more lights. It implements brightness and color control using buttons and dials on the Loupedeck.
func NewLightController ¶
func NewLightController(l *loupedeck.Loupedeck, position LoupedeckArea, lights []Light) *LightController
NewLightController creates a new LightController for a set of lights.
func (*LightController) Reset ¶
func (a *LightController) Reset()
Reset sets the brightness to 0 and color to the minimum supported by the light.
type LoupedeckArea ¶
type LoupedeckArea int
LoupedeckArea represents an area of the Loupedeck touch display.
const ( LeftTop LoupedeckArea = iota LeftMiddle LeftBottom RightTop RightMiddle RightBottom )
type RainbowLightP12 ¶
type RainbowLightP12 struct {
// contains filtered or unexported fields
}
RainbowLightP12 controls a Quasar Science Rainbow light bar (the original model, not Rainbow 2 or Double Rainbow), in DMX profile 12. In this mode, the light listens to a block of 12 DMX addresses:
dmxid+0: intensity (high 8 bits)
+1: intensity (low 8 bits) +2: color temp (2000k to 6000k mapped onto 0..255) +3: plus/minus green +4: crossfade fraction color/rgb high +5: crossfade fraction color/rgb low +6: red +7: green +8: blue +9: FX +10: FX rate +11: FX size
Right now, only intensity and color temp are used, but various special effect settings will be exposed in the future.
func NewRainbowLightP12 ¶
func NewRainbowLightP12(dmx *udmx.UDMXDevice, dmxid uint16) *RainbowLightP12
NewRainbowLightP12 creates a new RainbowLightP12 using a specific DMX controller and at a specific DMX address.
func (*RainbowLightP12) MaxColorTemp ¶
func (a *RainbowLightP12) MaxColorTemp() int
func (*RainbowLightP12) MinColorTemp ¶
func (a *RainbowLightP12) MinColorTemp() int
func (*RainbowLightP12) SetBrightness ¶
func (a *RainbowLightP12) SetBrightness(b int)
SetBrightness sets the brightness of the DMX light.
func (*RainbowLightP12) SetColorTemp ¶
func (a *RainbowLightP12) SetColorTemp(c int)
SetColorTemp sets the color temperature of the DMX light. The temperature should be specified in degrees K.
func (*RainbowLightP12) SetFX ¶
func (a *RainbowLightP12) SetFX(x int)
SetFX sets the light's FX setting.
func (*RainbowLightP12) SetFXRate ¶
func (a *RainbowLightP12) SetFXRate(x int)
SetFXRate sets the light's FX rate.
func (*RainbowLightP12) SetFXSize ¶
func (a *RainbowLightP12) SetFXSize(x int)
SetFXSize sets the light's FX size.
type RainbowLightP5 ¶
type RainbowLightP5 struct {
// contains filtered or unexported fields
}
RainbowLightP5 controls a Quasar Science Rainbow light bar (the original model, not Rainbow 2 or Double Rainbow), in DMX profile 5. In this mode, the light listens on two DMX addresses; the lower one is an 8-bit brightness and the upper one is an 8-bit color temperature.
func NewRainbowLightP5 ¶
func NewRainbowLightP5(dmx *udmx.UDMXDevice, dmxid uint16) *RainbowLightP5
NewRainbowLightP5 creates a new RainbowLightP5 using a specific DMX controller and at a specific DMX address.
func (*RainbowLightP5) MaxColorTemp ¶
func (a *RainbowLightP5) MaxColorTemp() int
func (*RainbowLightP5) MinColorTemp ¶
func (a *RainbowLightP5) MinColorTemp() int
func (*RainbowLightP5) SetBrightness ¶
func (a *RainbowLightP5) SetBrightness(b int)
SetBrightness sets the brightness of the DMX light.

func (a *RainbowLightP5) SetColorTemp(c int)
SetColorTemp sets the color temperature of the DMX light. The temperature should be specified in degrees K.
