reduce the program size (836 bytes vs 330 bytes in previous example), it is very important while ATtiny861 microcontroller only have 8192 bytes to store the program Port manipulation require bitwise calculation, it is a little bit difficult for a beginner but it has many advantage if you need...

the second timer is used to count for a fixed time and then generate an interrupt. Then a simple calculation is performed using the second fixed timer value, and the accumulated leading edges counted. The positive going edge count is then stored, and also reset every time the second timers ...
You cant set the current internal count of the timer. You must stop the timer to reset the count to the max of the interval. The interval is the time between ticks. There is nothing else we can use in the timer. The timer internal count reset happens automatically when the timer is ...
As more complex calculation and check inside ISR are introduced from v1.2.0, there is possibly some crash depending on use-case.You can modify to use larger HW_TIMER_INTERVAL_US, (from current 20uS), according to your board and use-case if crash happens.// Current 20uS #define HW_...
