6.16. Total Phase Beagle Debug Header
The Beagle I2C/SPI Protocol Analyzer is a non-intrusive USB-based bus monitor that can capture, display, and filter I2C
and SPI data as it appears on the bus. Using both the Data Center Software and Beagle analyzer, users can easily view
I2C bus traffic (up to 4 MHz) and SPI bus traffic (up to 24 MHz) in real time. Additional functionality allows engineers to
filter data against a wide variety of parameters, or instantly search for specific hexadecimal or ASCII data patterns during
a live capture. The Beagle analyzer is fully supported on Windows, Linux, and Mac OS X, and comes with free software,
free APIs, free technical support, and free software/firmware upgrades.
Total Phase manufactures powerful and affordable USB, I2C, SPI, and CAN tools for embedded systems engineers. The
complete line of Total Phase host adapters and protocol analyzers are the development and debugging tools of choice for
Fortune 500 companies, small businesses, and research institutions all over the world.
