Detailed Description

Interface for SPI bus access.

The ESPHome component implements this by delegating to its SPIDevice methods, allowing radio drivers to perform SPI transactions without depending on the ESPHome SPI framework directly.

Member Function Documentation

spi_disable()

virtual void esphome::home_io_control::SpiAccess::spi_disable ( )

pure virtual

Disable the SPI bus (deassert CS).

Implemented in esphome::home_io_control::IOHomeControlComponent.

spi_enable()

virtual void esphome::home_io_control::SpiAccess::spi_enable ( )

pure virtual

Enable the SPI bus (assert CS low).

Implemented in esphome::home_io_control::IOHomeControlComponent.

spi_read()

virtual uint8_t esphome::home_io_control::SpiAccess::spi_read ( )

pure virtual

Read one byte (MISO only, MOSI driven with 0).

Returns

Byte received.

Implemented in esphome::home_io_control::IOHomeControlComponent.

spi_transfer()

virtual uint8_t esphome::home_io_control::SpiAccess::spi_transfer ( uint8_t data )

pure virtual

Transfer one byte full‑duplex (MOSI→MISO).

Parameters

data	Byte to send.

Returns

Byte received from MISO.

Implemented in esphome::home_io_control::IOHomeControlComponent.

spi_write()

virtual void esphome::home_io_control::SpiAccess::spi_write ( uint8_t data )

pure virtual

Write one byte (MOSI only, MISO ignored).

Parameters

data	Byte to send.

Implemented in esphome::home_io_control::IOHomeControlComponent.
