ATmega328p u-kr and u-th
I have a couple in DIP version. Business as usual.   atm328p-pu dev id 1e 95 0f fuses virgin ffd962 check ckdiv8 /to remove it/, program: goes ffd9e2 check dwen, goes ff99e2...

Creating a single pulse in ATmega1608
Sanka1p wrote:is there any other way   Why it should be any other way. I exactly do this on my projects (if there is one pin free), with the difference that the light pulse...

0 and 100 percent duty cycle detection........
It does matter, for a perfect solution.   This project is similar to Synchronize external 1Hz with own 1Hz osc (from Timer2). It is possible if the scanning is 32Hz. With...

jgmdesign wrote:a pulse train 30Hz   What you know about: is it a precise one, is it a Fast PWM or perhaps Phase Correct?   I am asking, because not only one Interrupt...

0 and 100 percent duty cycle detection........
Depend on how serious or important the result is.   When No-pulse is detected, it can start a supervision, assigning Interrupt to monitored pin, to catch the exact moment of...

0 and 100 percent duty cycle detection........
jgmdesign wrote:whose duty cycle varies from 0 to 100%   I can imagine both cases, common is 'no-pulse' situation. Detect no pulse, measure H or L, that is it.

What can you do with Opto encoder?
It may have a mighty low angle resolution. If you can dig up this information, may be interesting.

I2C or serial communication between TWO atmegas of 3.3V and 5.0V
Put a resistor between. Not too small, though, because you will supply current into 3.3V device. Try 1k, and mind: it deteriorates I2C speed.
