I²C Protocol Analyzer

I²C stands for Inter-IC-Communications bus. It is a 2 wire synchronous serial bus standard, originally designed for on-board communications between ICs. It has been used for some off-board applications as well (like interacting with your Computer Monitor). It was designed by Phillips Semiconductors (now NXP.)

The I²C Protocol Analyzer is one of many signal decoders included with all DigiView Logic Analyzers.

The DigiView software provides extensive navigation, search, measurement, export, plot and printing capabilities to all signal types. The I²C Protocol Analyzer adds I²C specific decoding and configuration options.
