Start Io Signal Observer

Starts an Observer on a specific {iochannel,attibute} pair.

Arguments Description

io_channel_path (str): The io channel path should be in the format: HW::HwSignalName / PS::psChannelName.

attribute_name (str): HW type: it could be: { Voltage,

Current, DutyCycle only relevant for PWM (yaml field –> MeasurementAttribute: PWM), Frequency, Power: relevant only for PS_Channel, Resistance, RawValue, ShortCutToVbat, ShortCutToGnd, OpenLoad, LowVoltage}

Returns

bool: True if the observer is successfully started; otherwise, False.

For example, an Observer on that {iochannel,attibute} pair is already started and not stopped yet.

Example

Start Io Signal Observer HW::${HwSignalName} Voltage

Note

The received values can be retrieved once the observer is stopped.
