How to wake from sys_sleep() after a period of time?

Hi, I'd like to do some tasks regularly (let a cursor blink, for example), but still spend most of the time in a power saving state. It seems like sys_timer_start(timer_ix, ms_value); sys_sleep(); sys_timer_disable(timer_ix); would fit the bill, but I don't know if I can just choose any timer or if ...

Re: Solar Power

I don't know how much current the DM42 draws, but for standard USB compliance you'd have to provide 500mA at 5V. That means you would need at least 25 of these, and above that you'd need either a boost converter to get to 5V from the 3V you (ideally) get, or you connect the panels in pairs to get 6V...

Re: We need you for the 43S. Yes, you!

Hi,

I'd love to help too. I have never had a WP34, but I have a little C(++) programming experience on Linux/Windows (mostly Qt stuff).
Do you use git or another version control system?

Best regards
Gert

Re: DM42 : What a beauty !

I like the blue letters. I would buy one like that.
(I'm lusting after a second DM42 anyway, so I can leave one in the office and keep the other one at home.)
