Nettet8. sep. 2024 · I use the function request_irq () so that my function handling the interrupt is called on the rising edge and on the falling edge of my button by indicating "IRQF_TRIGGER_FALLING IRQF_TRIGGER_RISING". I formerly used the function gpio_to_irq (BUTTON_PIN). NettetIntroduction. The PCNT (Pulse Counter) module is designed to count the number of rising and/or falling edges of input signals. The ESP32 contains multiple pulse counter units in the module. 1 Each unit is in effect an independent counter with multiple channels, where each channel can increment/decrement the counter on a rising/falling edge ...
