remove() [1/2]

void CFastLED::remove ( fl::ChannelPtr channel )

static

Remove a channel from the LED controller list.

Removes the channel from the active controller list so it will no longer be updated by FastLED.show(). The channel object itself remains valid and can be re-added later if needed.

Parameters

channel

Shared pointer to a Channel instance

Note

Safe to call multiple times - no error if channel not in list

The channel object is not destroyed, only removed from the list

Example:

auto channel = FastLED.add(config);
// ... use channel ...
FastLED.remove(channel);  // Remove from controller list

                                                       {
    if (!channel) {
        return;
    }
    // Note: removeFromDrawList() now fires onChannelRemoved event
    channel->removeFromDrawList();
    // Remove from internal storage (safe if not found - erase is a no-op)
    channels().erase(channel);
}
