    lead acid charger schematic with maintenance charging

    3 stage charger lead acid battery schema I'm not exactly sure I understand the question: do you mean: 1) Current comming from the solar panels? (It's never the case anyway due to variation of the light during the day etc..) 2) The current from the bateries (never the case anyway due to cell...

    XP Regedit disabled! help!

    Just a word of warning.. With restore point.. It's all very nice, however if a trojan, worm, virus(es) are present, then of course the 'backup' zone will keep them. So I would be sort of careful with this and insure that the backup does not contain nasty little monsters.. :-) Cheers

The interrupt processing decide then that such thread must be interrupted (too long) or may continue.. And so on...

    What's the best OS for embedded?

    What Os is the best As the 'chinese officials' have declared being against "wintel (windows + intel) it makes sense to choose Linux. However you did not mentionned if your application is real time or not.. May be a simple RTOS with file handling would be sufficient ? :-)

    Windows NT and Intel iRMX which one is better

    I guess the advantage of iRMX is that it has a definite known time to answer an interrupt. NT guarantees absolutely nothing. As for example it may spend 100 milliseconds checking a physical drive:-( So if you are doing real time stuff.. You are stuffed as well ! Video being one of the most...

    a warning about design compile: fanout

    May be you're trying to drive to many entites with one single signal. try to share.. As you don't give a lot of details on the tool set used, or the language either it's really difficult to help you :-)

    Concept HDL/Orcad Capture simultaneous installation

    Be aware in PSD 15.1 that you have to install the libraries separately from the third CD for concept HDL though.. And effectively, there is no problem whatsoever. Cheers :-)
