WebRegister GPIO interrupt handler, the handler is an ISR. The handler will be attached to the same CPU core that this function is running on. This ISR function is called whenever any GPIO interrupt occurs. See the alternative gpio_install_isr_service() and gpio_isr_handler_add() API in order to have the driver support per-GPIO ISRs. WebThe threshold value set here means that when the value read by the touch-sensitive GPIO is below 40, the ESP32 should wake up. You can adjust that value accordingly to the desired sensitivity. Attach Interrupts. You need to attach interrupts to the touch sensitive pins. When touch is detected on a specified GPIO, a callback function is executed.
