WebThe value can also be used to determine whether the interrupt occurred on a rising or falling edge. A value of 0 implies a falling edge interrupt and a value of 1 implies a rising edge interrupt. unwatch([callback]) Stop watching for hardware interrupts on the GPIO. If callback is specified, only that particular callback is removed. In my previous tutorials on threaded callbacks we used edge detection of RISING and FALLING edges. Somewhere along the line, Ben introduced an option to test for BOTH falling and rising edges. I knew about this, but hadn’t tried it before. So, where previously we had the code… GPIO.add_event_detect(25, … See more The 10k resistor is a pull-down, to give the port a default status of 0/LOW/False. The 1k resistor is to protect the port.
