Feature Request: low power mode #16

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
Feature request: 

Device is always on and as it has no power switch it means that battery usage 
is high.  It would be nice to put device into low power mode if the button is 
held for 2 or more seconds in effect turning it off.

pushing the button will awake the device

Have implemented and now shutting down when button is pressed for 2sec.  

Power before implementation when idle is ~7.8ma

Power after implementation when idle is approx ~2.8ma

This is still too high and currently investigating why it's so.   

I thinks that the regulator VR1 may be the problem.  Still doing testing.

I think its down to the linear regulator, but need to confirm on a board and 
isolate
