Supported Protocols

Supported Protocols

The Saleae Logic software includes the following protocol analyzers:
    Asynchronous Serial
    SPI (Serial Peripheral Interface)
    CAN (Controller Area Network)
    I2S Audio / PCM
    Manchester, Differential Manchester, Bi-Phase Space, and Bi-Phase Mark
    Synchronous Parallel
    PS2 Keyboard & Mouse
    Atmel SWI (Single Wire Interface)
    LIN (Local Interconnect Network)
    MDIO (Management Data Input/Output)
    USB Low Speed and Full Speed
    SMBus (includes PMBus and Smart Battery)
    HDLC (High-Level Data Link Control)
    Modbus RTU & ASCII
    HD44780 Parallel LCD
    SWD (ARM Serial Wire Debug)

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.
