Detailed Description

Example HAL implementation for 32-bit SPI.

This is a template implementation showing how to create a platform-specific HAL for 32-bit SPI communication.

Key Requirements:

• 32-bit SPI transfers (or 4x 8-bit transfers)
• MSB-first byte order
• Full-duplex operation
• SPI Mode 0 (CPOL=0, CPHA=0)

Platform Adaptation:

Replace placeholder comments with actual hardware code for:

• STM32: HAL_SPI_TransmitReceive()
• ESP32: spi_device_transmit()
• Arduino: SPI.transfer32() or 4x SPI.transfer()
• Linux: ioctl(SPI_IOC_MESSAGE)
