The Zephyr west tool is a powerful workspace manager, but it is admittedly pretty feature-rich: there’s a lot of functionality buried inside that tool! I thought it would be interesting to share a few tips and tricks that I use with west to make my Zephyr development workflow a little smoother.

Let’s suppose you’re building an even smarter fishtank. You’re adding temperature and salinity sensors, logging timestamped readings to flash. The struct is your binary record format – every field at a fixed byte offset, so you can read it back on any system that knows the layout. You use fixed-width types from stdint.h and pack(1) to strip out compiler-inserted padding. This is the advice I had always received and given, and it’s correct – as far as it goes.
