I know there is more that can be done with these And there are other ways as well but this is what i know works thus far. To set your timer just add it to your sketch: TIMER 3Ĭode: TCCR3B = (TCCR3B & 0xF8) | value TIMER 4Ĭode: TCCR4B = (TCCR4B & 0xF8) | value TIMER 5 The rest i do not know the frequencies: but I can tell you tell you the values available. There are pin mappings to Atmega8 and Atmega 168/328 as well. TIMER 0Ĭode: TCCR0B = (TCCR0B & 0xF8) | value TIMER 1Ĭode: TCCR1B = (TCCR1B & 0xF8) | value TIMER 2 A diagram showing the correspondence between the pins on an Arduino board and those of the ATmega2560 microcontroller. If someone knows these more accurately than i have listed please feel free to let me know so i can change em. I can not guarantee the exact freq's but they should be close. So the rest of these frequencies are taken from other ref's. Unfortunate I do not have a oscilloscope cause I'm poor. They tell you what timers there on.įor example pin 2 is OC3B which is timer 3. Mostly I'm making this cause it felt there wasn't greatly one place to go for this info.Ĥ OC0B //never mess with this one at it directly effects major timing Īll that is really important above is the numbers. Lastly to all the OG's here that know this stuff cause it was feed to em in a bottle. but they don't work the same on the mega's There is a lot of info on this for other boards like UNO etc. Thats great! The french in the data sheet says yes there are timer,s and yes they can be changed, but there was no dumb dumb version in there to say to do this, type this here. Getting all this data together for my projects has taken me much effort since a lot of it was hard to completely understand when every place said refer to the datasheet. Want to change the frequency on your your arduino mega?Īlot of this info is out there on the web but not much of it is all in one place and as easy to find as right here on Arduino's Forums.
