pub fn new_mcp4911(spi: SPI, chip_select: CS) -> Self

Create a new instance of a MCP4911 device.

impl<SPI, CS> Mcp49xx<SpiInterface<SPI, CS>, Resolution10Bit, DualChannel, Buffered>

pub fn new_mcp4912(spi: SPI, chip_select: CS) -> Self

Create a new instance of a MCP4912 device.

impl<SPI, CS> Mcp49xx<SpiInterface<SPI, CS>, Resolution12Bit, SingleChannel, Buffered>

pub fn new_mcp4921(spi: SPI, chip_select: CS) -> Self

pub fn new_mcp4922(spi: SPI, chip_select: CS) -> Self

Create a new instance of a MCP4922 device.

impl<DI, RES, CH, BUF, E> Mcp49xx<DI, RES, CH, BUF> where
    DI: WriteCommand<Error = E>,
    RES: ResolutionSupport<E>,
    CH: ChannelSupport<E>,
    BUF: BufferingSupport<E>, 

pub fn send(&mut self, command: Command) -> Result<(), Error<E>>

Send command to device.

This will return an error if the command is not appropriate for the current device:

• If the channel is not available it will return Error::InvalidChannel.
• If the value is too big it will return Error::InvalidValue.
• If buffering is not supported it will return Error::BufferingNotSupported.

Otherwise if a communication error happened it will return Error::Comm.
