Comment(by SimonKagstrom):
A general comment first: Thanks to all for the testing and experiments,
the messages here have been very clear and to the point!
Johannes: 100 interrupts per second sounds right when the threshold is 0
(so that new datums is signalled by the interrupt) - the data rate is set
to 100Hz by default. With threshold 0, the interrupt rate should not
change depending on if the device is shaken or not - it always interrupts
at each datum in that case.
As for your earlier test: The interrupt is only enabled when the device
file is opened - so if I understand that test correct, you are closing the
device during the sleep and in that case the interrupt stream should stop.
DigitalPioneer: Your first problem certainly sounds like the original
issue, but as for the screen corruption I have no idea :-). To me it
sounds like a more general problem. Andy: Could it have something to do
with the "manual" bitbang used by the accelerometer code? (I'm thinking if
it can somehow interfer with the Glamo).
