GPIO Output pin not raising the expected voltage

[pekon94]

Hello,

I am facing the following issue:

I am using the blinky sample of Zephyr to control the output of a pin. When this pin is  any of the LED pins of nrf5340dk, the output is the expected one (voltage is either 0 or 3volts depending on the status of the pin). When I am using any other pin (I tried with some other P0 and P1 pins) the voltage is not changing as expected.

I even used the voltage flags (3P3 and 5P3) and changed the ACTIVE state of the pin, but nothing worked. I also checked that the gpio_pin_set function was returning 0 (successful).

Could you please help with this?

Hi

Have you checked out the DevAcademy, which has a full fledged course on the nRF Connect SDK fundamentals, and has a specific chapter with exercises related to configuring and setting GPIOs here.

Best regards,

Simon

Hello Simonr,

thank you for pointing me to devacademy. I was missing that for P1 pins configured as gpio pins, the gpios parameter should be pointing to gpio1 and not gpio0. I have changed that and now it is working as expected.

Glad to hear that Petros! I guess we can close this case then.
