First off, kudos to the maemo team for making such a nifty and easy-to-use interface for the keypad LED. I spent a inordinate amount of time just tinkering with the brightness, blinking period, and so forth :-) For those interested, the relevant sys entries are here: /sys/class/leds/keypad Should be self explanatory, particularly if you turn on the blinking from the control panel so you can cat out the values it uses for delay_off and delay_on, etc. My question is this: for the default trigger source (timer), is the blinking just a hardware PWM built into the CPU or is the CPU involved in counting timer interrupts to handle on/off periods and toggling the LED? I ask because there was some discussion on ITT about how someone had their n800 run down overnight with the LED left on. It seemed unlikely but I wanted to make sure a bunch of CPU cycles weren't being burned to run it.
Thanks- Larry _______________________________________________ maemo-developers mailing list [email protected] https://maemo.org/mailman/listinfo/maemo-developers
