Interrupts in Arduino not working (for detecting zero crossing) In my previous thread, I learned about the H11AA1 optocoupler, which can be used instead of the 4N35 to detect zero crossings with Arduino. Arduino has a specific function for detecting interrupts: attachInterrupt(digitalPinToInterrupt...
attachInterrupt(0, zero_cross_detect, RISING); // Attach an Interupt to Pin 2 (interupt 0) for Zero Cross Detection Timer1.initialize(freqStep); // Initialize TimerOne library for the freq we need Timer1.attachInterrupt(dim_check, freqStep); // Go to dim_check procedure every 75 uS (5...
See the attachInterrupt() function for details. PWM: 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the analogWrite() function. SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication using the SPI library. LED: 13. There is a built-in ...

The Arduino functionsattachInterrupt() anddetachInterrupt() can only be used for external interrupt pins. These are different interrupt sources, not discussed here. Timer interrupts A timer can generate different types of interrupts. The register and bit definitions can be found in the processor data...
Serial.println (encoder0Pos, DEC);// debug - remember to comment out// before final program run// you don't want serial slowing down your program if not needed}/* to read the other two transitions - just use another attachInterrupt() ...
SPI.attachInterrupt(); The value from master is taken from SPDR and stored inSlavereceivedvariable. This takes place in following Interrupt Routine function. ISR (SPI_STC_vect){Slavereceived = SPDR;received = true;} 3. Next in void loop () we set the Slave arduino LED to turn ON or OFF...
Pin interrupts are supported through attachInterrupt, detachInterrupt functions. Interrupts may be attached to any GPIO pin, except GPIO16. Standard Arduino interrupt types are supported: CHANGE, RISING, FALLING. Pin Functions The most usable pin functions are mapped to the macro SPECIAL, so calling ...
