WebI'll try separate events for GPIO.RISING and GPIO.FALLING as I do want to know both when the gate opens and closes. – TomG. Jul 19, 2014 at 0:35. Beware that you cannot add a rising and a falling callback for the same pin. You have to use "both" and then read out the GPIO in the callback, which gives outdated results at best. RPi.GPIO is just ... WebThe EXTI (EXTernal Interrupt/Event) controller consists of up to 40 edge detectors for generating event/interrupt requests on STM32L47x/L48x devices. Each input line can be independently configured to select the type (interrupt or event) and the corresponding trigger event (rising, falling, or both).

WebMay 5, 2016 · Good point regarding the double reading of the pin state. The library I am using does not allow both a rising interrupt and a falling interrupt on the same pin. It was updated to include a BOTH interrupt, but it doesn't seem possible to specify 2 callbacks depending on rising or falling edge. horned back toadWebDec 31, 2024 · The GPIO pins when configured as interrupt inputs, will have a Schmidt trigger circuit enabled at the input ports (STM32L4xx family, for example). A rising edge detection may happen or may not happen when you drop to just 1.5 V and then go back to 3.3 V.

WebMar 20, 2013 · When you run the code it gives you a message “Waiting for falling edge on port 23”. If you press button 1, it will terminate the program as before and give you a message. “Falling edge detected.”. If, instead of button 1, you press button 2, you’ll get a message. “Rising edge detected on port 24”. WebI am programming the Zybo (Zynq-7000) board. I am using an AXI GPIO in the PL, configured as digital input, that is connected to an external PWM signal. I have configured the GPIO to trigger an interrupt for both rising and falling edges and a timer, so I can calculate the duty cycle of the signal. The problem is that, in the interrupt handler ...
