random touch pins trigger
Posted: Thu Feb 07, 2019 2:12 pm
Hello people,
My esp32s uses pins 4,15,32,27 in my application.. I use deepsleep mode and once when the touch pins are high the esp32 wakes up. The issue is the buttons are working fine . but in random if i use 32 pin 4 triggers, also the same for 27 and 15, 4 triggers. where could be the problem i suspect its pull up resistor, i used internal pull up, set pull mode. but still its an issue. I use esp32s. an usb to uart and battery to power it. but while i upload code i use usb to uart. and my pins are clearly initialized and setup.
