Detailed Description

Implementation of SPI communication for Raspberry Pi using Linux SPI device interface.

This class provides an interface to the SPI bus on Raspberry Pi platforms by accessing the Linux device (e.g., /dev/spidev0.0). It inherits from HardwareSPI and implements all required methods for SPI communication, including data transfer, transaction management, and configuration.

Note

This class is only available when USE_RPI is defined.
