attachInterrupt(void (*isr)()) - Attach a interrupt (callback function) for the timer of the object. detachInterrupt() - Detach current callback of timer. start(long microseconds = -1) - Start the timer with an optional period parameter. stop() - Stop the timer setFrequency(long frequen...
this function receives as first input the pointer to the timer, as second the value of the counter in which the interrupt should be generated, and as third a flag indicating if the timer should automatically reload upon generating the interrupt. ...
This library enables you to use Interrupt from Hardware Timers on supported Arduino boards such as AVR, Mega-AVR, ESP8266, ESP32, SAMD, SAM DUE, nRF52, STM32F/L/H/G/WB/MP1, Teensy, Nano-33-BLE, etc.As Hardware Timers are rare, and very precious assets of any board, this ...
so in this tutorial, we will learn how to use the Timer delay function as well as the Timer ISR (Interrupt Service Routine) and blink two individual LEDs. You can also check out theArduino Timer TutorialandPIC Timer tutorialto check how to use timers with othe...
Timer interrupt number. Not all timers support all of these values; see the descriptions for each value. Values: TIMER_UPDATE_INTERRUPT - Update interrupt, available on all timers. TIMER_CC1_INTERRUPT - Capture/compare 1 interrupt, available on general and advanced timers only. TIMER_CC...
The first timer is configured to count the leading edge of the incoming square wave, 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 ...
hasInterrupt() 4.Examples Following examples are provided inSTM32Exampleslibrary (available with Arduino Library manager): Timebase_callback.ino This example shows how to configure HardwareTimer to execute a callback at regular interval. Callback toggles pin. Once configured, there is only CPU load...

Note that setting the period will change the attached interrupt and the PWM output frequency and duty cycle simultaneously. enablePwm(PwmPin, DutyCycle) Generates a PWM waveform on the specified pin. Output pins for Timer2 are PORTB pin 3 and PORTD pin 3. On Arduino, these are digital pins...
