Protocol decoders
This is a list of supported protocol decoders (PDs) and decoders which we might want to write in the future (or users might want to contribute).
See Protocol decoder API for details on how the decoders work in sigrok, and Protocol decoder HOWTO for a quick introduction about how to write your own decoders.
