Tiny24 bipolar ADC - DC offset help?
Quote: The datasheet does talk about being able to read the offset, but what kind of offset are they talking about? That would be the offset of the conversion circuitry inside...

ATmega128L question
Quote: I assume ther is no way to force a reset from the code?? You can enable the watchdog and let it reset the avr. Something on your board seems to take a long time to start...

ATmega128L question
One thing that comes to my mind is the startup time of the crystal (if you are using one?!). How have you set the SUT fuses? If you have a very short startup time, try selecting a...

ADC using interrupt on ATmega324p
Quote: Any other tips on making my program work? You haven't set the ADC clock frequency (The ADPSn bits in one of the adc registers). My guess is you're running the adc too fast...

No EEPROM write after sleep mode
Here's my guess as to what is happening: RETI automatically re-enables interrupts, so you probably are getting several int0 interrupts. Especially if int0 is configured to trigger...
