R/W GPIO port in Zephyr instead of pins

Happy to help.

I have not come across that sample, but as the functionality is available, it should not be hard to use.

BR, Naeem

Thank you, will do - I see, precisely what I was looking for. Could have dug a bit more!

Noticed now if I'm not mistaken there is only one sample that uses the port function to drive a 7 seg display. Just seemed like it would be a common thing.

Hello,

Thank you for contacting DevZone at NordicSemi.

Yes, that functionality is supported by Nordic chips, and you can read in the product specification about the registers within the gpio peripheral.

Also, Zephyr GPIO API provides the functionality to toggle, set, clear the pins(bits) of the port.

zephyr/drivers/gpio.h has functions like gpio_port_set_bits and gpio_port_clear_bits

I encourage you to explore the Zephyr GPIO API, the GPIO peripheral in the SoC documentation, and if needed the NRFX HAL GPIO.

BR, Naeem
