Esp32 enter deepsleep5/3/2023 Instead, this is run on the RTC so you'll have very little power consumption when you enter deep sleep and have one of the touch pins configured as wakeup source. Small side note: using the touch sensor as a wakeup source does not require the ULP. This tells the ESP32 to keep the touch sensor on when going to sleep. Here we want to make an exception for the touch sensor, and that's what we do with esp_sleep_enable_touchpad_wakeup(). Normally, when you enter deep sleep, the ESP32 powers down as many peripherals as it can to save power.
