Hardware Hacking: I2C Bus Sniffing #Arduino #CircuitPython @CUJOAI @Hackaday

András Tevesz demonstrates and explains some of the fundamentals of hardware hacking recon and internals of wire protocols.

I2C or (eye-squared-C) is a synchronous, multi-master, multi-slave, packet-switched, single-ended, serial communication bus invented in 1982 by Philips Semiconductors. Its good for our use case, as it has the simple two-wire SDA (Serial Data line) and SDC (Serial clock line) implementation.

A Beagleboard, Adafruit Trinket, Arduino Leonardo and a handy Saleae logic analyzer are used.

Software includes using Adafruit_PlatformDetect and Adafruit_Blinka compatibility layer for CircuitPython to Python.

Read the details in the post here and on Hackaday.
