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).
| Protocol | Output ID(s) | Status | Description | Comments |
|---|---|---|---|---|
| Basic / microcontrollers / embedded | ||||
| SPI | 80% | Serial Peripheral Interface (SPI) protocol. | Mostly working, though some details need to be fixed or improved. | |
| I2C | 80% | Inter-Integrated Circuit (I2C) protocol. | Mostly working, though some details need to be fixed or improved. | |
| UART | 80% | Universal Asynchronous Receiver Transmitter (UART) protocol. | Mostly working, though some details need to be fixed or improved. | |
| Automotive / industrial / embedded | ||||
| CAN | 0% | |||
| Flexray | 0% | |||
| Embedded | ||||
| JTAG | 0% | |||
| SWD | 0% | |||
| PC | ||||
| USB (full-speed) | 80% | Universal Serial Bus (USB), full-speed, low-level protocol. | ||
| LPC | 0% | |||
| FWH | 0% | |||
| ISA | 0% | |||
| PCI | 0% | |||
| SMBus | 0% | |||
| Consumer IR | ||||
| Nokia NRC17 | 0% | |||
| Sony SIRC | 0% | |||
| Philips RC-5 | 0% | |||
| Philips RC-6 | 0% | |||
| Philips RC-MM | 0% | |||
| Philips RECS80 | 0% | |||
| Miscellaneous | ||||
| IrDA | 0% | |||
| Serial EEPROMs | ||||
| AT93C46 | 0% | Atmel AT93C46 serial EEPROM protocol | ||
| Displays | ||||
| 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.
| Protocol | Input ID(s) | Output ID(s) | Status | Description | Comments |
|---|---|---|---|---|---|
| Serial EEPROMs | |||||
| TODO | SPI | 0% | SPI-attached serial EEPROM. Datasheet: TODO. | ||

| Wii Nunchuk | I2C | 70% | Nintendo Wii Nunchuk I2C-based protocol. | Preliminary, untested. | |
... and many, many more.
Non-protocol data analysis decoders:
- How many data bytes are in the data stream?
- What's the min/max/avg data value?
- ...
