That depends a little bit on the kernel driver. If your (sysfs) driver supports the interrupt-driven select/poll interface there shouldn't be any effect. However, if select/poll is not supported (by the kernel driver) sensord needs to continuously read the accelerometer values in fixed intervals which slightly increases power consumption of the device (sensord reading sysfs node, even if no new data is available). -- Markus _______________________________________________ MeeGo-dev mailing list [email protected] http://lists.meego.com/listinfo/meego-dev
