This YEP defines the has-measure-trigger trait. Daemons implementing this trait allow measurement to be software triggered over the RPC.
In many cases, it's relevant to tell a sensor "begin measurement now". This software triggered measurement pattern is very common. This trait standardizes this common sensor interface pattern within the yaq ecosystem.
This trait requires is-sensor: see YEP-302.
This trait defines the concept of "looping". When a sensor is looping, it should self-trigger the moment the previous acquisition is done. In certain cases, setting a sensor to looping makes client implementations much easier. Daemons will remain always busy while looping.
This trait defines the concept of a "measurement_id".
This is an integer that should increase every time the measure message is called.
get_measured returns this measurement_id as a channel.
If set to true, the daemon will begin to loop measure as soon as it starts. By using this config, users may ignore software triggering and treat this sensor as a pure asyncronus measurement device.
parameter: loop: boolean parameter: loop: default: false
Initiate a measurement. Returns integer, measurement ID.
Stop looping measurement.
