Creating an I2C slave interface for a sensor or peripheral

You’re creating a stand-alone module to bundle a few hardware sensors, or have an independent microcontroller that stays awake and needs to wake the main system depending on configurable environmental triggers. What’s the easiest way to let this unit receive orders and communicate results? An I²C slave! Inter-Integrated Circuit–I²C–is specifically designed to provide an easy…

Eclipse saves my ass and the day

It started with the best of intentions, as these things are wont to do.

Make: building AVR and Arduino firmware on the command line

I’ve had a few requests from visitors to my old (and now defunct) electrons site for the AVR Makefile.  Originally created in 2003, and finally included in the resources for an AVR-related Linux Journal article back in 2005, it turns out it’s still pretty useful so I’m replicating the original Makefile and instructions here, with…
