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.

Low-level protocol decoders

Protocol decoders that only require raw probes/signals as input (and don't require any already decoded data from other PDs).

HD44780	0%	HD44780 character LCD protocol
Transition counter	90%	Counts rising and falling edges in the signal. Mostly working.

... and many, many more.

Ideas:

• Number of clock cycles / rising-edges / falling-edges / transitions / etc. (total or per-signal)
• Min/Max/Avg distance between two events (rising edge, falling edge, signal lenths, etc.)
• ...

High-level protocol decoders

Protocol decoders that do not (only) have raw signals/samples as input, but rather also data which was already decoded by one or more low-level PDs.

Non-protocol data analysis decoders:

• How many data bytes are in the data stream?
• What's the min/max/avg data value?
• ...
