Tiny25 internal oscillator temp drift
Both the ATtiny1634 and ATtiny828 have some new 8 bit registers that I have never noticed in any ATtiny before. OSCTCAL0A – Oscillator Temperature Calibration Register A...

USI overflow interrupt on ATTiny85 hangs/resets the chip
You are using the old SIG_USI_OVERFLOW vector name. Change to the new USI_OVF_vect vector name for the ATtiny85. The old vector name was also used for other USI AVRs that the new...

ATmega32 timer0 CTC mode fail, timer2 same(?) code works
According to the data sheet timer0 (1<<CS02)|(1<<CS01)|(1<<CS00) is External clock source on T0 pin, Clock on rising edge. Either you comment is wrong if you...

How to increase Atmega Timer resolution?
A longer gate period has greater resolution, which is not the same thing as accuracy. A .1 second gate will give 10 Hz resolution +/- 10 Hz. A .2 second gate will give 5 Hz...

How to increase Atmega Timer resolution?
Alex, Look at CTC mode timer operation. It will generate a periodic OC0x Interrupt Flag Set up to every 16.3ms. It will also toggle the OC0x output pin state up to every 16.3ms....

How to increase Atmega Timer resolution?
Since the OP only needs a positive or only a negative going edge (choose one, not both) every 200 ms, it should be able to reach 200 ms when going same edge to same edge timing....

How to increase Atmega Timer resolution?
You are correct that consistent delays at both the start and end of your measurement cycle are not a problem. No, the number of instructions executed before the ISR changes pin 1...

How to increase Atmega Timer resolution?
This is one really valuable lesson Lee has for all of us. What we want is not always what we need. For example, we get irritated when a frequency reading alternates between 10000...
