Timer2 Library with Ascynchronus Mode

Projects Programming
1

Hi,

I have found a library for Timer1 on the playground and it says that it can be easily configured for other Timers. However,if we consider the use of Timer2 in asynchronous mode, there are some other aspects which need to be considered and the resgister bits are also a bit different.

Can someone share a link of library for using Timer2 in ascyncrhonus mode. Moreover I am finding it hard to understand some of the operators such as _BV and setting bits of registers using C. Can someone share link for learning the operators and stuff like that. I have also considered using Watch dog timer. Does any library exist for the use of Watch Dog Timer.

Nothing on the Timer1 page mentions asynchronous mode. What do you mean by asynchronous mode for a timer?

Asynchronous mode refers to the situation in which we can use the timer with an external oscillator. It is more often used in getting the Arduion out of sleep ( Power save mode )
