ESp32 GPIO32 and GPIO33 not working together as RTC GPIO for EXT1
I want to use GPIO 32 and GPIO33 as a RTC GPIO for waking up by ext1 // We use unsigned long here since 32 is a long #define GPIO_BIT_MASK ((1ULL<<GPIO_NUM_32) | (1ULL<<GPIO_NUM_33)) esp_sleep_enable_ext1_wakeup(GPIO_BIT_MASK, ESP_EXT1_WAKEUP_ANY_HIGH); it get trigger even if the 32 and 33 pin is no...
