ESP32 Input only pins as Interrupts for Deep sleep wakeup
Posted: Thu Oct 25, 2018 8:08 am
Hi,
We are planning to input only pins GPIO34-39 as External interrupts to wake-up from deep-sleep. I have following queries regarding this
1)Do these pins any pulldown/additional circuitry to protect them from external HW and reduce current consumption.
2)Do we need to isolate them using rtc_gpio_isolate();
edit : Because when I even touch the pins the board is waking up, which is not desired
Thanks,
Karim
