Hi all, I am searching for a system call or hack that could turn the screen on and off for saving battery power. Also all other ideas for power saving are welcome.
Let me explain the program a bit: I am developing kind of unusual application, its a complex psychological questionaire with a lot of different forms. These forms should be show 6 times a day for 3 weeks to the subject. I cannot use the Attention- or Alarm-manager, because the system wont let me use normal forms after waking up, just dialogs are allowed, I think I asked this before. The solution was, I dont let the program quit, ignoring all appStopEvent's. This is OK because the only reason why the user got the palm pilot, is to take part of the study. So my programm is always active for three weeks. This let the battery, we use Palm m500 devices, go down after 15 - 20 hours. The poor user is told to put the machine allways in the craddle, but they all are humans and forget about these from time to time. First running out of battery interrupts the study sequence which is bad enough But one other strange effect is, that date and time could change when battery goes empty, this is horrible for my program. So putting the palm pilot into the craddle for recharching after running out of power, sometimes results in complete confusion. I am trying to save power as much as I can, I used SysTaskDelay to put the processor into doze mode for the time it is not used, but this didnt helps very much.
