Re: LED blinking during suspend
Hi, OK. Lets say there are pending notifications that the user needs to see. If I set the LED light on, and suspend the phone - does it stay on automatically - or do I need more magic? What about the current consumption? How badly would this affect battery life? I'm looking at getting just enough information to decide whether this is an idea worth pursuing or not.

I'm too lazy to check if the kernel will turn it off for you in suspend :) What about the current consumption? About 5 mA per LED. About 50 mA per LED if the LED has the base resistor problem. Normal suspend current with GSM on should be somewhere around 8 mA, maybe a bit less. So the LED would take a considerable bite out of that, From a usability point of view, I'm quite sceptical about this idea of using a LED as a permanent indicator. LEDs are very limited in the amount of information they can signal to a human being, and if you have a lot of different states to signal, the patterns may not be very intuitive. I think it would be interesting to try to find a way for resuming the display really quickly, so that one could just bring up the screen, check the status indicators for any news, and then send the device back to sleep. - Werner ___ hardware mailing list hardware@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/hardware
