create()

fl::shared_ptr< SpiChannelEngineAdapter > fl::SpiChannelEngineAdapter::create ( fl::vector< fl::shared_ptr< SpiHwBase > > hwControllers, fl::vector< int > priorities, fl::vector< const char * > names, const char * adapterName )

static

Create unified adapter managing multiple controllers.

Parameters

hwControllers	Vector of hardware controllers (SpiHw1, SpiHw16, etc.)
priorities	Per-controller priorities (must match hwControllers.size())
names	Per-controller names (must match hwControllers.size())
adapterName	Unified adapter name (e.g., "SPI_UNIFIED")

Returns

Shared pointer to adapter, or nullptr on error
