Triggering from the sensor using a tilt switch.

[pneumatic]

I'm trying to use the ball tilt switch as a cheap accelerometer to trigger one pass of the image.

This is a naive implementation. It does some simple hysteresis counting to debounce the very noisy input. Aside the from attached file, you only need to add this to the appropriate place in the Makefile:

program-sweep: sweep.hex

and then
$ make program-sweep
should do it.

Comments?
