Debug and Test your I2C System using I2C Tools

Accelerate Your I2C Debugging

Total Phase offers multiple tools to develop and debug I2C systems, including host adapters and protocol analyzers. I2C host adapters like the Aardvark I2C/SPI Host Adapter and Promira Serial Platform allow users to emulate master or slave I2C devices to test sytems. I2C protocol analyzers like the Beagle I2C/SPI Protocol Analyzer provide real-time visibility into the I2C bus, including bit-level timing, bus data and errors, and much more. Learn more about our selection of I2C tools and how they can be used to advance your own I2C projects.
