-Subject: [PATCH] : lis302dl-wakeup-configuration.patch
-
-Setup accelerometer interrupt to wake the device up
-
-From: Simon Kagstrom <simon.kagstrom@gmail.com>
-
-The threshold implementation recently broke this functionality. This
-patch reinstates it again and simplifies the code a bit. It only
-supports one of the two lis302dl interrupt sources now (which is the
-only connected one on the openmoko). If you need to configure both, buy
-an Iphone!
-
-(Or flame this patch)
-
-
-Note that, as before, the device immediately wakes up when put to sleep
-with the wakeup configured. The interface is therefore not currently
-very useful, but to use it do e.g.,
-
- echo 1 1 1 180 0 1 > wakeup
-
-The value is of the form
-
- X Y Z THRESHOLD DURATION SPEC
-
-X, Y and Z are threshold values, given as a value > 0, < 0 or 0 to
-specify if an interrupt should be generated for high or low thresholds
-or neither (off). THRESHOLD specifies the threshold that must be
-exceeded, in mg. DURATION specifies the time in milliseconds for which
-the acceleration should be measured. SPEC is either '1' or '0' and
-specifies if the thresholds should be taken all together or one at a
-time ('and' or 'or' mode).
-
-Echoing '0' to the file turns off the interrupts.
