LED Controls🔗

Device Support

NextUI's LED Controls currently only support the TrimUI Brick.

Support for the TrimUI Smart Pro will be addressed in a future update.

A comment on color reproduction

The TrimUI Brick is a budget device with budget LEDs. Don't expect the colors to display accurately.

LED Control App🔗

On home screen, select Tools, then select LedControl.

The app provides the following options.

LED Selection🔗

The TrimUI Brick has the following configurable LEDs.

  • Two LEDs on the front of the device for each function button (FN1 & FN2)
  • Two LEDs under the triggers (one under L1 & L2 the other under R1 & R2)
  • One LED bar on the top of the device

When in the LED Control App you can use Left Trigger and Right Trigger to cycle between these LEDs.

Effects🔗

Each LED can be configured with the following effects.

Effect Name Description
Static Keep the LED(s) on and static
Blink 1 Quickly blink 1 time
Blink 2 Quickly blinks 2 times
Linear Slowly increase the brightness and then fall back to off
Breathe Slowly increase the brightness and slowly decrease the brightness
Interval Breathe Slowly increase the brightness and slowly decrease the brightness, with a longer pause between "breaths"

Color🔗

The color of LEDs. Use Left and Right on the D-Pad to cycle through the colors.

Speed🔗

The speed of breathing effect in milliseconds.

Brightness🔗

The brightness level of the LEDs. Setting this to 0 will turn the LED off.

Info Brightness🔗

The brightness of LED when informing you about something.

Currently, this is only supported by:

  • Power Button turning red alerting for low battery
  • Front Function Button LED blinking when entering sleep

Setting brightness to 0 will turn the LED off.

Ambient Mode🔗

Only Supported By Certain Emulator Cores

Ambient light effects are only supported by the built in Libretro cores.

Ambient light mode makes your LEDs change color to match the dominate color on screen during gameplay.

To enable ambient mode (in a supported emulator) follow these steps:

  1. While in game press the Menu button
  2. Select Options
  3. Select Frontend
  4. Scroll down to the Ambient Mode line and turn it on. You can select to use all LEDs or just a specific one.

Ambient Mode sets the LED Brightness to Maximum

We found that lower brightness levels will result in displaying in incorrect color.
