Thanks again and keep burning the candle for the blind...

Hi Andrew, As a newbie I was digging deep on the “surface” I found Javier Valencia code dealing with timers. I found also some improvements added by Bill Perry for use timer4 on Atmega32u4. I also read data sheet and try to figure out what to add/correct in your program. I might be totally wrong in ...

Andrew, thank you for your express answer... :D . I read at the datasheet about the 32U4 hardware timers. It has 4 times as stated: One 8-bit Timer/Counter with Separate Prescaler and Compare Mode Two 16-bit Timer/Counter with Separate Prescaler, Compare- and Capture Mode One 10-bit High-Speed Timer...

Now I try to use it with board Pololu A-Star 32U4 and run in a trouble. Well, I am very new in programming, but understood that the problem is with setting t...
