nRF52 GPIO usage

[Dajgoro Labinac]

Hi.

I'm trying to figure out how to properly use GPIO pins, but so far I did not find a document explaining how to use GPIO with nrf included functions. I found bits and pieces of code which use GPIO but that is no documentation. How to set up GPIO port? How does GPIO work exactly? How do I address and write the entire GPIO port? Do I have to write to registers or are there functions for that? How are GPIO pins addressed for the nRF52832, is it just the pin number of port 0?

Hi,

The GPIOs can be controlled using the GPIO abstraction API, or through the registers directly. There is many threads about GPIO usage here on DevZone, for instance here.

You address the pins by the pin number of the port, so P0.00 is adressed 0, P0.01 is 1 and so on.

Best regards,

Jørgen

Thanks, for some reason googling the nrf gpio did not get me to that page.
