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).

| SPI | spi | 80% | Serial Peripheral Interface (SPI) protocol. | Mostly working, though some details need to be fixed or improved. |
| I2C | i2c | 80% | Inter-Integrated Circuit (I2C) protocol. | Mostly working, though some details need to be fixed or improved. |
| UART | uart | 80% | Universal Asynchronous Receiver Transmitter (UART) protocol. | Mostly working, though some details need to be fixed or improved. |
| 1-Wire | 0% | |||

| UNI/O | 0% | |||
| Automotive / industrial / embedded | ||||

| Miscellaneous | ||||
| IrDA | 0% | |||

| DALI | 0% | |||
| PWM | 0% | |||

| 7-segment display | 0% | |||
| Other | ||||
| Transition counter | transitioncounter | 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:

- What's the min/max/avg data value?
