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.

I2C overview

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.

We fully support the I2C specification
