nrf52832 gpio with pullup current

[yaron]

Hi

I have noticed that when I configure any GPIO with "NRF_GPIO_PIN_PULLUP" option, the CPU current is raised by approximatly 200 uA. (It doesn't matter if the GPIO is configured as input or output). Is this the default behaviour? Can this be prevented somehow? Thanks Yaron

Is the GPIO you have configured as a pull up, being pulled down? If so you'd expect to see 3v or so across the 15k or so pull up resistor which is about 200uA

This makes sense, thanks

Suppose the GPIO was configured as pull-up, and was not being pulled-down, would it still consume 200uA?

I had similar behavior, even with no pull. The pin is externally connect to GND through a push button, if the swtich is pressed (GPIO in low) the device present the default sleep current. but when button is released there's a idle current around 25uA

did you get the answer for this?
