I finally got around to ordering a couple more Flotilla modules. It's seriously hard to find the Flotilla stuff on the store. It's like you're trying to hide it! I couldn't find any links or catagories for Flotilla, and only found the bits I needed because I could search for them (and know what I wanted). you really should be screaming about this, as its really great hardware.
I got a joystick and a matrix, so I could port some of the games I've previously run on Arduino over to it, including my version of Defender. Here's a link to the Video on Twitter.
Sniff already supports Matrix and JS and they've been tested by a few people, so the code pretty much ran first time (actually 2nd time).
I also got a Motion. I know Robin did some work with this on his buggy, but I never integrated the code into the main code base, as the Motion is a particularly tricky bit of hardware. It's all working, so I'll release it in the next version of Sniff (31?).
