Tutorial: I2C Hacking Demistified - Igor Stoppa, OpenSource Technology Center Intel

Sign up or log in to save this to your schedule and see who's attending!

This tutorial will show how to create and operate a custom I2C peripheral.

The system analysed is comprised of an I2C master (Intel Edison) and an I2C slave (Arduino-compatible board).
It will be shown how to use simple, affordable, tools for debugging the interaction between the 2 devices.
The tools are a bus device emulator (Bus Pirate) and a SW logic analyzer (PulseView/Sigrok).

They will be used for testing the transmission over the I2C bus (with the Bus Pirate), synthesizing messages on the bus, while sniffing for the exchange, at electrical level, with the logic analyser, and running the output through a sw message decoder.

Finally, it will be discussed how to add SW profiling/tracing to the live system, so that some debugging functionality is still present, even if the HW tools are not present anymore (device in the field vs on the workbench).
