Common trait implemented for every driver

Required Methods§

Source

fn get_driver(&self) -> Driver

Gets the underlying driver type

Source

fn get_version(&self) -> PicoResult<String>

Gets the driver version string

Source

fn get_path(&self) -> PicoResult<Option<String>>

Gets the path to the loaded driver

Source

fn enumerate_units(&self) -> PicoResult<Vec<EnumerationResult>>

Returns a list of discovered serial numbers

Source

fn open_unit(&self, serial: Option<&str>) -> PicoResult<i16>

Source

fn enable_channel( &self, handle: i16, channel: PicoChannel, config: &ChannelConfig, ) -> PicoResult<()>

Set up a channel with the supplied config

Source

fn disable_channel(&self, handle: i16, channel: PicoChannel) -> PicoResult<()>

Source

fn set_data_buffer( &self, handle: i16, channel: PicoChannel, buffer: Arc<RwLock<Pin<Vec<i16>>>>, buffer_len: usize, ) -> PicoResult<()>

Give the driver a buffer to write data into

Source

fn start_streaming( &self, handle: i16, sample_config: &SampleConfig, ) -> PicoResult<SampleConfig>

Starts the device streaming

Source

fn get_latest_streaming_values<'a>( &self, handle: i16, channels: &[PicoChannel], callback: Box<dyn FnMut(usize, usize) + 'a>, ) -> PicoResult<()>

Gets the latest streaming values

Source

fn stop(&self, handle: i16) -> PicoResult<()>

Stops the device streaming

Provided Methods§

Source

fn check_version(&self) -> Result<(), DriverLoadError>

Check that the driver meets the minimum version tested with these wrappers
