Public Methods

::fidl::WireResult< ::fuchsia_hardware_spi::Device::Transmit> Transmit (const ::fuchsia_hardware_sharedmemory::wire::SharedVmoBuffer & buffer)

Sends the data in buffer to the device.

Allocates 72 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_hardware_spi::Device::Receive> Receive (const ::fuchsia_hardware_sharedmemory::wire::SharedVmoBuffer & buffer)

Receives data from the device into buffer.

Allocates 72 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_hardware_spi::Device::Exchange> Exchange (const ::fuchsia_hardware_sharedmemory::wire::SharedVmoBuffer & tx_buffer, const ::fuchsia_hardware_sharedmemory::wire::SharedVmoBuffer & rx_buffer)

Simultaneously transmits and receives data. The size fields of tx_buffer and rx_buffer must

be the same.

Allocates 96 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_hardware_spi::Device::RegisterVmo> RegisterVmo (uint32_t vmo_id, ::fuchsia_mem::wire::Range && vmo, ::fuchsia_hardware_sharedmemory::wire::SharedVmoRight rights)

Registers a VMO and transfers ownership to the driver.

vmo_id: The ID chosen by the client that will be used in operations on this VMO.

vmo: The handle, offset, and size of this VMO. IO operations on this VMO will be relative to

the offset and size specified here.

rights: A bit field of SharedVmoRight values indicating how this VMO may be used. Callers

should assume that the driver will map and/or pin the VMO using these rights.

Allocates 88 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_hardware_spi::Device::UnregisterVmo> UnregisterVmo (uint32_t vmo_id)

Unmaps and/or unpins the VMO and returns the handle to the caller.

Allocates 56 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_hardware_spi::Device::TransmitVector> TransmitVector (::fidl::VectorView<uint8_t> data)

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

Allocates 24 bytes of response buffer on the stack. Request is heap-allocated.

::fidl::WireResult< ::fuchsia_hardware_spi::Device::ReceiveVector> ReceiveVector (uint32_t size)

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

Allocates 24 bytes of request buffer on the stack. Response is heap-allocated.

::fidl::WireResult< ::fuchsia_hardware_spi::Device::ExchangeVector> ExchangeVector (::fidl::VectorView<uint8_t> txdata)

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

buffer.

Request is heap-allocated. Response is heap-allocated.

::fidl::WireResult< ::fuchsia_hardware_spi::Device::CanAssertCs> CanAssertCs ()

Returns true if the device can call |AssertCs()| and |DeassertCs()|.

Allocates 40 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_hardware_spi::Device::AssertCs> AssertCs ()

Assert CS for this device.

Returns ZX_ERR_NOT_SUPPORTED if there is more than one device on the bus.

Allocates 40 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_hardware_spi::Device::DeassertCs> DeassertCs ()

Deassert CS for this device.

Returns ZX_ERR_BAD_STATE if CS is already deasserted.

Returns ZX_ERR_NOT_SUPPORTED if there is more than one device on the bus.

Allocates 40 bytes of message buffer on the stack. No heap allocation necessary.
