how to do interrupt drive GPIO input in python?

[dony71]

RPi has this interrupt driven GPIO input detection

GPIO.add_event_detect(pin_number, GPIO.BOTH, callback=callback_function)

 

 

Orange Pi has already this python GPIO function

https://github.com/duxingkei33/orangepi_PC_gpio_pyH3

 

But I see only gpio.input(pin_number) function for GPIO input detection

Anybody can answer whether possible to substitute RPi interrupt driven GPIO input detection?

Yes. use WiringOP from WereCatf https://github.com/WereCatf/WiringOP

 

example(from my )

void rpmInterrupt(void) {
          pulseCounter++;
}

....

void rpmFan(void) {
      pthread_setcanceltype(PTHREAD_CANCEL_ASYNCHRONOUS, NULL);
      wiringPiSetup () ;
      pinMode(PIN_RPM, INPUT);
      pullUpDnControl (PIN_RPM, PUD_UP) ;
      wiringPiISR (PIN_RPM, INT_EDGE_FALLING, &rpmInterrupt);
      while (1)  {
        rpm=(pulseCounter/HALL_PULSE)*60 ;
        pulseCounter = 0;
        delayMicroseconds ( 1000000 ); //cheÑk every 1 second
      }
}

It works. But this is C++

any python wrapper for this?
