Hello
After 20 years I want to restart with Programming in Pascal. I have Raspberry Pi 3b and want to use the GPIO pins.
I have wiringpi and its wrapper (h2wiringpi). The code for steering LEDs (reading/writing) works fine. But I am struggling massively with interrupt function. I have a button and the pin shall observe the status of the button. So if I push the button an interrupt shall be occurs. Honestly although researching in www for endless hours I have no idea how to do that (although there are some rough information on this website). So I ask you if you can support me, by sending an simple example code how to realize this. I highly would appreciate this.
