Introduction

ImpulseOSD supports up to 64 LEDs using the common WS2812 protocol. We could drive even more LEDs, but felt 64 is more than sufficient for a mini quad application. Each LED can be configured with a different color and/or action which are explained further below. For easy configuration of the LEDs you can copy a single LED to many others with a LED copy feature.

NOTE: The 5V regulator on our OSD hardware are not capable of driving many LEDs!!! The WolfPDB has a 1.5A 5V regulator which we successfully tested with 8 LEDs using a Tramp or Unify HV. Be careful with a 5V VTX - that could burn out your regulator!!! Use a separate 5V regulator with a capacitor if you want to drive many LEDs.

LED actions

• OFF: LED is off.
• ON: LED is on and will display the color configured under Color2.
• ARMED: When disarmed, the LED uses the color configured under Color1. When armed, the LED uses the color configured under Color2.
• THROTTLE: Depending on the throttle position, the LEDs will display a color which is interpolated between Color1 and Color2
• KNIGHT: Anyone that remembers the car K.I.T.T. from the 80s series Knight Rider will know what this is - the rest can just quickly look it up on youtube ;) We recommend configuring at least 4 consecutive LEDs with KNIGHT mode (the original had 8 "LEDs"). Tip: Set Red for Color2 to 255. Other colors work of course too, but that will give you the original effect.
• SPARKLE: Select a color with Color2 and set SPARKLE mode for at least 2 LEDs (we recommend 4 or more). The LEDs will show with the color you selected and they will "sparkle" in white randomly.
• AUX1-AUX7: Depending on the AUX position, the LEDs will display a color which is interpolated between Color1 and Color2

LED strip menu

Enter the menu (yaw left while disarmed for more than two seconds), go to SETUP and then LED STRIP.

• LED NUMBER: Select the LED number you wish to configure.
• LED ACTION: Select one of the LED actions explained above.
• COLOR1 RED: Red color gain from 0 to 255 for Color1
• COLOR1 GREEN: Green color gain from 0 to 255 for Color1
• COLOR1 BLUE: Blue color gain from 0 to 255 for Color1
• COLOR2 RED: Red color gain from 0 to 255 for Color2
• COLOR2 GREEN: Green color gain from 0 to 255 for Color2
• COLOR2 BLUE: Blue color gain from 0 to 255 for Color2
• COPY LED Enters the copy LED menu. Explained further below.
• SAVE+EXIT: Save all changes (and also changes made in other menus except the VTX menu) and exit the menu.
• BACK: Go back to the previous menu. Changes are not discarded, but they are not saved until you exit with SAVE+EXIT from any menu.

LED copy menu

Enter the menu (yaw left while disarmed for more than two seconds), go to SETUP, then LED STRIP, then COPY LED.

On the top you will see the configuration of the current LED selected - the SOURCE. The idea is that you copy the SOURCE to a range of LEDs starting from DEST START and ending in DEST END. Once you have configured DEST START and DEST END simply roll right on COPY.
