Public Methods

::fdf::WireUnownedResult< ::fuchsia_hardware_spiimpl::SpiImpl::GetChipSelectCount> GetChipSelectCount ()

Returns the number of chip select lines available or provided by the driver instance.

To be used as a limit on the acceptable values for the `chip_select' field in the Exchange()

and ExchangeVmo() methods.

Caller provides the backing storage for FIDL message via an argument to `.buffer()`.

::fdf::WireUnownedResult< ::fuchsia_hardware_spiimpl::SpiImpl::TransmitVector> TransmitVector (uint32_t chip_select, ::fidl::VectorView<uint8_t> data)

Half-duplex transmit data to a SPI device; always transmits the entire buffer on success.

Caller provides the backing storage for FIDL message via an argument to `.buffer()`.

::fdf::WireUnownedResult< ::fuchsia_hardware_spiimpl::SpiImpl::ReceiveVector> ReceiveVector (uint32_t chip_select, uint32_t size)

Half-duplex receive data from a SPI device; always reads the full size requested.

Caller provides the backing storage for FIDL message via an argument to `.buffer()`.

::fdf::WireUnownedResult< ::fuchsia_hardware_spiimpl::SpiImpl::ExchangeVector> ExchangeVector (uint32_t chip_select, ::fidl::VectorView<uint8_t> txdata)

Full-duplex SPI transaction. Received data will exactly equal the length of the transmit

buffer.

rights is a bit field containing SpiVmoRight values, and determines the read/write

permissions used by the implementation when pinning or mapping the VMO.
