Hi all, the problem which faced openhantek kind of recently is a new class of cheap softscopes. For example Hantek 6022Bx don't even have a HW trigger. There is no problem to get data, there is a problem to represent the data for the human.
It means, to make sigrok usable for this case, soft triggering should be implemented too.
