Beagle I2C/SPI Protocol Analyzer

The Total Phase Beagle I2C/SPI Protocol Analyzer is a dedicated bus-monitoring tool that provides non-intrusive, real-time capture of I2C (SMBus supported), SPI and MDIO communications with 20 ns bit-level timing resolution. Unlike a general-purpose logic analyzer, the Beagle is purpose-built for serial bus analysis, it delivers high-performance bus monitoring in a small, portable, USB bus-powered package, with fast, interactive, real-time visibility into the protocol layer of your embedded system. Data is streamed over High-speed USB directly to your computer, so recording is nearly limitless and no transactions are missed.

Features at a glance

Supporting I2C up to 4 MHz, SPI up to 24 MHz and MDIO up to 2.5 MHz, the Beagle handles the serial bus speeds found across modern embedded systems. The included Data Center software provides real-time transaction display with bit-level timing down to 20 ns, plus filtering and searching of captured data, so you can watch I2C and SPI packets as they occur on the bus. Its compact, USB-powered form factor and passive monitoring mode make it well suited to permanent installation in test fixtures, debug setups and long-running bus-health monitoring.

Beagle I2C/SPI protocol analyzer: real-time, non-intrusive monitoring

Because the Beagle taps the bus passively rather than driving it, it can stay connected through the entire development cycle, from early board bring-up through final production verification, providing a continuous record of bus activity. The Data Center software displays captured traffic in true real time with LiveDisplay, applies user-defined filters with LiveFilter to hide traffic that is not for the address you are monitoring, and lets you search captures with LiveSearch. Saved capture files can be shared with colleagues and exported to CSV for further analysis.

Scriptable captures with the Beagle Software API

The Beagle Software API is a flexible, well-documented interface for building custom capture and validation applications. It provides 32-bit and 64-bit support with language bindings for C, C#, Python, .NET, VB.Net and VB6, ships with example files, and is cross-platform across Windows, Linux and macOS. A LabVIEW instrument driver is also provided for test-bench integration. This makes it straightforward to automate long-running captures, log multiple buses and fold the Beagle into production test scripts.

Applications

The Beagle I2C/SPI Protocol Analyzer is used wherever engineers need always-on, zero-overhead visibility into a serial bus:

• Sensors: accelerometers, pressure, temperature and light sensors communicating over I2C or SPI.
• Video display standards: VGA, DVI and HDMI all carry I2C, so the Beagle can identify communication issues on the I2C lines used for display configuration.
• Industrial and home automation: motor controls and lighting controls.
• Audio processing: codecs and signal-processing devices.
• EEPROM and peripheral debugging: debugging communication between a master and slave I2C/SPI peripherals such as EEPROMs.
