I am making good progress on a few of my projects and I am pondering the next steps on the vault hardware. Once I get a solid program complete, and that is getting really close, I want to design a project specific board for the controller. I am at a crossroads of unknown direction in watchdog timer options. I have seen some references to watchdog code to be dropped in to a sketch and have seen hardware watchdog elements as well. As a matter of fact, Jon sells one here on Superhouse I could integrate. Being as I am looking at creating an all in one board design though, I think I would probably want to integrate that into my board instead of an add-on. I am leaning towards hardware based timer. The reason being, since I don’t have any experience with this stuff, I would believe that if your processor hangs up, your software based timer is gonna hang too?
Anyone with experience that wants to kick in some thought on this?
