Nope, there's currently no OUTPUT_LOGIC (and also no OUTPUT_ANALOG) yet, but both are features we want to eventually have indeed. > should add a "OUTPUT_LOGIC" (or similar) ? If so, I would be happy to > provide a patch. Please join us on IRC (#sigrok on Freenode) for a discussion of the details, this might be somewhat non-trivial to implement properly. The libsigrokdecode side is doable, but the PulseView side of the feature will probably require some amount of non-trivial work.
