Current leakage on multiprocessor system.
Quote:Use the mega168's RTC. Power the master MCU from either the power supply or the coin cell via diode OR. When the power supply is off the master MCU will enter the Power Save...

GPIO interrupt programming help needed
If the pulse is stable (no bouncing) and last for milliseconds you can probably poll the state of the pin at a place in the code that suits you (MAIN?). Then you don't need to...

Current leakage on multiprocessor system.
This can often be solved by using diodes, but I don't know exactly how your system is interconnected.

newbie-problem with external interrupts on AT90CAN128 (asm)
malvina, As you can see there is more than one way to skin a cat. Personally I'm with MBedders team. Since you write your code, there is no reason why you would enable an...

newbie-problem with external interrupts on AT90CAN128 (asm)
BTW, I hope you have some more code after your "sei" otherwise your program will run into your interrupt handler and eventually cause a reset. A forever loop would prevent that...

newbie-problem with external interrupts on AT90CAN128 (asm)
My guess is that the long Interrupt vector table is your problem. Maybe try with hardcoded IRQ address.I have not checked if "int1addr" is the right name for your model but I...

Can use reset pin for logic input? (newbie)
The pin is by default reset. You need to program a fuse to make the pin to work as I/O. When you have done this you cannot load new program code into the chip never ever.

Atmega128 ADC - Sampling Frequency.
For only 8-bit result I've been using 1MHz ADC clock with good results. OTOH I take 16 samples in a row on each channel and use average of that (slowly changing signal).
