setDriverPriority()

bool fl::ChannelManager::setDriverPriority	(	const fl::string &	name,
		int	priority )

Change the priority of a registered driver.

Parameters

name	Driver name (case-sensitive, e.g., "RMT", "SPI", "PARLIO")
priority	New priority value (higher = preferred, e.g., 9000 > 5000)

Returns

true if driver was found and priority updated, false if name not found

Note

Triggers automatic re-sort of driver list by priority (descending)

Changes take effect immediately on next enqueue()

Higher priority drivers are selected first during canHandle() iteration
