I have two problems with Patterns (digital outputs generator). I have already sent similar post via Feedback option in WaveForms menu, but no answer has come.
In both cases I need to generate burst of phase-shifted pairs of pulses (quadrature signals) which idles high.
a) The signals measured on DIO differ from signals drawn by Patterns designer (see "Patterns_pulses_case" project).
b) The phase of Patterns changes when using project with only one pair of outputs (see project "DIO0_DIO3_correct_phase") or with multiple pairs (project "ModulEXT1_DI test") while the outputs pattern configuration is identical.
The scope signals in all projects are yellow= DIO0, blue=DIO3.
Could You try to reproduce/explain a) and b), please?

Dear support,
I have two problems with Patterns (digital outputs generator). I have already sent similar post via Feedback option in WaveForms menu, but no answer has come.
In both cases I need to generate burst of phase-shifted pairs of pulses (quadrature signals) which idles high.

The scope signals in all projects are yellow= DIO0, blue=DIO3.
Could You try to reproduce/explain a) and b), please?
Thank You
