Hi,
When I define my nrf52840 pin 0.19 as input put, and there is no connection to any sensor.
Then I use gpio_pin_get_dt() to get pin 0.19 status, the status is high.
Even if I reset the pin 0.19 status, it will return high in 10 seconds.
I guess the root cause is the null connection with floating voltage cause nrf52840 to define pin 0.19 as high.
How can I modify the gpio config to avoid the floating voltage?
Thanks!
I have already disable the qspi dts in my nrf52840dk_nrf52840.overlay file, so the qspi node won`t use pin 0.19.
