fl::SpiChannelEngineAdapter Class Reference

Detailed Description

Adapter that wraps HW SPI controllers for ChannelManager.

This adapter implements the IChannelDriver interface by delegating to existing SpiHwBase controllers (SpiHw1/2/4/8/16). It handles channel data batching, transmission coordination, and polling state management.
