Help on new (perhaps) power up/down design
Hi, i'm new and this is my first post, so be gentle :)
I was pondering on elegant power up.down design for my
CarPuter :). It's in finish design phase when i saw this site,
so i have been changing everything from your experience...
The idea is:
The computer should became active on any user activity in the car.
Any means regular using in entering driving.
Set the computer to Standby on 10 min.
Set the computer to Hybernate on 1h.
This would not drain battery to much and allow me the next
The essential is this.
I want the computer to reactivate on Drivers Dor opening/closing
and to stays awake while ingnition is on...
I was thinking to do the following:
If the door opens there are 2 that may happen:
1. the computer is turned on (not hybernating)
- Pres any key - let's say Z
2. the computer if of (is hybernating)
- Press the power key to wake it..
While the key is in the ignition (or the contact is on)
Press any key (let's say again Z) every 5 mins to
keep the computer awake.
Now, how do i do this. I have basic electrical knowledge.
But i'm professional programer and am designign a 3 key
complete operational interface for CarPuters and the software to
do virtuali anything with it (wait and see).
So a preety 'complete' explanation is what i need :)
Thanks a lot and hope i did not bored you with long post and bad english...
