![]() TIFRx - Timer/Counter Interrupt Flag Register.TIMSKx - Timer/Counter Interrupt Mask Register.ICRx - Input Capture Register (only for 16bit timer).TCCRx - Timer/Counter Control Register.You can change the Timer behaviour through the timer register. Timer3, Timer4, Timer5: Timer 3,4,5 are only available on Arduino Mega boards. In the Arduino work the tone() function uses Timer2. In the Arduino world the Servo library uses Timer1 on Arduino Uno (Timer5 on Arduino Mega). If you change Timer0 registers, this may influence the Arduino timer function. In the Arduino world Timer0 is been used for the timer functions, like delay(), millis() and micros(). In the Arduino firmware, all timers were configured to a 1kHz frequency and interrupts are generally enabled. The timer hardware can be configured with some special timer registers. Normally the system clock is 16MHz, but the Arduino Pro 3/3V is 8Mhz, so be careful when writing your own timer functions. Timer3, Timer4 and Timer5 are all 16bit timers, similar to Timer1.Īll timers depends on the system clock of your Arduino system. First 3 timers (Timer 0, Timer1 and Timer2) are identical to the ATmega168/328. They are almost identical to previous chips but only differs in memory size. The Arduino Mega series is based on the Atmel AVR ATmega1280 or the ATmega2560. 8bits means 256 values (two to the power of 8) where 16bit means 65536 values (two to the power of 16) which is much higher resolution. The most important difference between 8bit and 16bit timer is the timer resolution. Timer0 and Timer2 are 8bit timer, where Timer1 is a 16bit timer. Both have 3 timers, called Timer0, Timer1 and Timer2. These chips are pin compatible and only differ in the size of internal memory. The Arduino board is based on the Atmel AVR ATmega168 or the ATmega328 microchip.
