This is a list of ideas for specific protocol decoders 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 decoders

Standard protocols that have raw signals/samples as input

Protocol Status Comments
Basic / microcontrollers / embedded
SPI 0%
I2C 0%
USART/RS232 0%
Automotive / industrial / embedded
CAN 0%
Embedded
JTAG 0%
PC
USB 1.1 0%
USB 2.0 0%
USB 3 0%
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%

... and many, many more.

Custom / application-specific protocols that have raw signals/samples as input

Protocol Status Comments
Serial EEPROMs
AT93C46 0% Atmel AT93C46 serial EEPROM protocol
Displays
HD44780 0% HD44780 character LCD protocol

... and many, many more.

Non-protocol data analysis decoders / analyzers that have raw signals/samples as input

  • 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.)
  • ...

... and many, many more.

High-level decoders

Protocols that rely on other lower-level protocols

Protocols that do not have raw signals/samples as input, but rather an already-preprocessed bytestream generated by one of the low-level decoders.

Protocol Input protocol Status Comments
Serial EEPROMs
TODO SPI 0% SPI-attached serial EEPROM. Datasheet: TODO.
Displays
SA8807A SPI 0% SPI-attached LCD. Datasheet: Sames SA8807A.
EA eDIPTFT43-A I2C 0% I2C-attached LCD. Datasheet: EA eDIPTFT43-A.
TODO USART/RS232 0% TODO
ADC
AD7291 USART/RS232 0% I2C-attached ADC. Datasheet: Analog Devices AD7291.

Some ideas

  • AT93C46:
    • CS (chip select)
    • SK (clock)
    • DI (data from chip to outside)
    • DO (data from outside into chip)
    • Has start bit, opcodes, data following transmission
  • 4-bit interface to HD44780 LCD, take two nibbles in sequence, based on clock line, and assemble them into a whole byte. Scripted plugin could do this, then pass the data back to the UI for display.

... and many, many more.

Non-protocol data analysis decoders / analyzers

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