  • PS2 Keyboard & Mouse
  • Atmel SWI (Single Wire Interface)
  • LIN (Local Interconnect Network)
  • BISS-C
  • MDIO (Management Data Input/Output)
  • USB Low Speed and Full Speed
  • HDMI-CEC
  • SMBus (includes PMBus and Smart Battery)
  • HDLC (High-Level Data Link Control)
  • Modbus RTU & ASCII
  • MIDI
  • HD44780 Parallel LCD
  • SWD (ARM Serial Wire Debug)

I3C Protocol Support

We plan on officially bringing I3C protocol support to Saleae Logic, and we currently have a working solution! If you're interested in more details, please contact us.
The I3C analyzer will be released as our first "premium" analyzer, meaning that it will require a paid license to use it within our software (we're currently working out the details behind how this might work). We believe that we can provide an amazing developer experience at a price point that is a great deal for customers who are already using new protocols, and at the same time, helps us generate enough revenue to continue working on new features. We welcome any and all feedback!

Analyzer User Guides

We provide user guides for a handful of our protocol analyzers, which we have listed in the link below.

More Protocol Analyzers

Some Logic users have created their own protocol analyzers. The following list of analyzers are available but not officially supported by Saleae.

Do all Saleae logic analyzer models support these protocols?

Yes. However, you will need to use a device with sufficient bandwidth to record the original signal. For instance, Logic 4 simply does not have the bandwidth required to capture and decode USB full speed. Logic 4 has a maximum digital bandwidth of 3 MHz, and USB full speed requires a digital bandwidth of at least 12.5 MHz.

What Happened to the UNI/O Analyzer?

Unfortunately, we have not yet ported the UNI/O analyzer from Logic v1 into the newer Logic v2 software. Specifically, it requires separate API functions that we simply haven't had the chance to implement yet. It's not on the roadmap at the moment, though we would like to gauge user interest in this before we commit to it, as porting this analyzer into Logic v2 would require quite a bit of work as compared to porting our other analyzers.
