Trait Implementations

impl<'a> Driver for Dac<'a>

fn command(
    &self,
    command_num: usize,
    data: usize,
    _: usize,
    _: AppId
) -> ReturnCode

Control the DAC.

command_num

• 0: Driver check.
• 1: Initialize and enable the DAC.
• 2: Set the output to data1, a scaled output value.

fn subscribe(&self, minor_num: usize, callback: Callback) -> ReturnCode

subscribe lets an application pass a callback to the driver to be called later. This returns ENOSUPPORT if not used.

fn allow(
    &self,
    app: AppId,
    minor_num: usize,
    slice: AppSlice<Shared, u8>
) -> ReturnCode

allow lets an application give the driver access to a buffer in the application's memory. This returns ENOSUPPORT if not used.
