(...) Actually, the sensors themselves don't generate an interrupt. The interrupt to read the sensors is from a timer, and it just cycles through the sensors waiting to read the next one.

OK, so I had forgotten that for whatever reason legOS rotation sensors are very, very sensitive to dying batteries. I think that when underpowered, they either don't generate an interrupt or the voltage on the interrupt is too weak and the signal (...) (24 years ago, 27-Jul-00, to lugnet.robotics.rcx.legos)
