Title: Alarm Wake-Up on Sansa E200 via AS3514
Post by: redbull74 on December 31, 2007, 04:25:38 AM

I am missing the alarm wake-up feature on the sansa E200. So i had a look into the AS3514 feature list and i saw:

Real Time Clock
– ultra low power 32kHz oscillator
– 32bit RTC sec counter
– selectable alarm (seconds or minutes)

So i think it should be possible to implement it. Is currently anyone working on it?
Or has anyone the datasheet of the AS3514 and can send it to me so that i can implement the feature for the sansa E200?

Google is your friend:

Also, if you dont want to send them your info. then ask on #rockbox, one of the devs ought to have it.

as far as i heard from other developers the feature can't be implemented because no cpu wake up is possible with the "selectable alarm" feature :-(
