clearAllDrivers()

void fl::ChannelManager::clearAllDrivers

(

)

Remove all drivers from the manager.

Note

Clears the entire driver registry

Useful for FastLED.reset() with CHANNEL_DRIVERS flag

Waits for all drivers to become READY before clearing (1 second timeout)

Also clears any exclusive-driver filter set by setExclusiveDriver*(). The filter names a driver in the registry being emptied, and addDriver() consults it, so keeping it would silently disable every subsequently added driver.

    FL_DBG("ChannelManager: Waiting for all drivers to become READY before clearing");
 
    // Wait for all drivers to become READY before clearing
    // This prevents clearing drivers that are still transmitting
    waitForReady();
 
    FL_DBG("ChannelManager: Clearing " << mDrivers.size() << " drivers");
 
    for (auto& entry : mDrivers) {
        if (entry.driver) {
            entry.driver->setPollNeededCallback(IChannelDriver::PollNeededCallback());
        }
    }
 
    // Clear all drivers (shared_ptr handles cleanup automatically)
    mDrivers.clear();
 
    // Drop the exclusive-driver filter along with the registry it refers to.
    // Leaving it set would name a driver that no longer exists, and
    // addDriver() consults it -- so every driver registered afterwards would
    // arrive silently disabled, with no diagnostic and nothing to clear it.
    mExclusiveDriver.clear();
