I've been using a script that wait's for a falling_edge on a GPIO Pin. The pin is pulled up to high (by the script, not physical) by default and pulled to ground over a low resistor by a button (COM-00097). It works fine but i've heard that when using components like above polling would be a better solution scince the microelectronics could take damage so i have following questions:
1)Is it generally safe to use the GPIO-Pins like described in the setup?
2)What is the maximum current a circuit should draw when using interupt?
Due to serveral functions the script distinguishes between a short signal an a one-second period the button is pushed. Could a current for one second do any harm to the chipset on long term?
Thank you in advance.
