Should reduce amount of cpu wakeups with expensive computations.
2014-09-16timer: Support timeouts > 8sLars-Dominik Braun2-13/+64
2014-09-16Auto stop alarmLars-Dominik Braun1-4/+10
Currently triggers assert in timer.c
2014-09-16Finally fix speakerLars-Dominik Braun7-134/+62
Use one timer for LED/speaker. Not sure why two did not work.
2014-08-26speaker: Fix beepLars-Dominik Braun1-9/+20
Finally beeps. XXX: nope, it does not.

2014-08-19Switch to new timer, fix usabilityLars-Dominik Braun1-62/+102
Seems to work so far, gyro is a little too sensitive.
2014-08-19timer: Support arbitrary timer valuesLars-Dominik Braun2-16/+32
FIXME: large values do not work yet.
