What meter are you using? I'm going to get one like it.
The only pins connected to the chip comes from the AVRISP mkii pinout for uploading sketches.
I unplugged all of them and now it really is "bare-bone" (also disconnected the programmer) and re-measured the current and finally it's at 120 nanoAmps!
Also, is it possible to wake the chip from sleep using a button press without using keypad2.h, but instead with a pin Interrupt function?
Ahaaa!At least your reading almost exactly agrees with mine, now that you removed all the extra stuff *cough* .
Is it possible to use the low power interrupt function to give full power to the IR receiver to power it up for the next key press signal?
Well, in my head, I always thought the receiver is the one that's always on listening for the transmitted signals. So it's consuming a lot of power when hooked it up to the the atmega chip.If I was working with a transmitter, I wouldn't try to save power as much, because the power is only consumed when you press a button.So you think there's no way I could get an IR receiver that draws 0.35mA to draw less and still work?
