Useful alternative to switch-case state handling in embedded code
From 2 comments
Very nice! Anything that allows something more sophisticated than switch:case in embedded systems are welcome! Also, state machines are way too often overlooked as a proper model…
aylons on HNThanks for sharing! I'm working on a device and I've been searching for a good FSM library in C with no dynamic allocation :)

Interest in using it in embedded projects
From 2 comments
I'm impressed by this and like it a lot. If you don't mind a 'drive-by' feature request: it would be fantastic if you were to support the PlantUML state DSL:…
samatman on HNSame here, I've started 2 or 3 times and not liked any of my own implementations, this might actually be useful to me tonight.

From 1 comment

I've only tested with StarUML, but the plan is to support more tools

Quantum Leaps QP/QM framework

aylons on HNDepending on the application, I'll use a Finite State Machine pattern, but if I need something more complex I'll use QM QP/C (which is uses a hierarchical state machine pattern).…

xstate
From 1 comment
A must read for anyone interested https://statecharts.github.io/ Also I highly recommend to check out `xstate` TypeScript library. It's a breeze to work with it.
