[OpenTRV-dev] Custom Arduino shield

[Damon Hart-Davis]

Yes, I'd like to keep such avenues open if possible.

Unfortunately I have another day's standing on a roof, and two days' writing before I can even pack the V0.09 stuff for Bo and play with my ATmegas.

(Bruno, I don't suppose you'd like to join me for an AVR programming party this weekend for a few hours?  First I have to get the bootloader in and then start with some trivial hello-world code...)

And even if we end up with more compact designs, thinking of it from the point of view of designing a shield would help gel what pins to use for what. In particular, one of the good points he has in the video is that you'd want a custom shield to be compatible with other standard shields such as the Ethernet or the Wi-Fi one so that they can work together.
