Wake up from suspend-mode on touchscreen
Platform: Embedded Linux
Device: 7 inch touchscreen with arm v7
Qt Version: 4.7.2
I currently have a QTimer configured to start every X seconds. And a SLOT which is signaled on timeout that has a system command: #
@system("echo mem > /sys/power/state");@
This puts my processor into deep sleep mode. The device is configured to wake up on a touchscreen event.
This is a very sloppy implementation of the touch screen wake/sleep. Ideally I would like to have suggestions to improve on this with the following capabilities.
I don't want the 'first' touch to be recorded on the device which is used to wake up the device.
I want to be able to check for touch events before I timeout.
Any help is appreciated!
