Detailed Description

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 () 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.
