Functions for controlling the phase of a demo signal.
The phase defines the starting point in the period of the signal that is generated, as well as the ending point.
The phase is defined as a number between 0
and 1
, where 0
defines the beginning of the period (0°
) and 1
defines the end of the period (360°
).
Several of the demo signal types support setting the signal phase, but others don't. Use tiepie_hw_oscilloscope_channel_demo_has_phase() to find out whether the selected demo signal type supports setting the phase.
By default the phase is set to: 0
.
