In Topic: Sizing a Battery?

03 September 2010 - 02:20 AM

Here are some illustrative power consumption values - measured current on USB VCC line (Fluke 179):

  • 30 mA - Idle (no application), Thread.Sleep(Timeout.Inifinite)
  • 32 mA - Thread.Sleep() with onboard LED on
  • 45 mA - Running while(true);
  • 48~50 mA - Deployment (flash programming)
I have some difficulties with PowerState.Sleep(...) method, it seems not to be working properly, I could not get below 30 mA - it would require further investigation to see how exactly power saving mode is implemented (if at all).

Thanks for the reply CW2. I just got my boards in and will let Josh (OP) have at it with a meter. It might convince him to get cracking on his project! :rolleyes:
