Set/Clear multiple GPIO pins

[dario.sortino]

Hello,

I am developing my own application using nRF Connect SDK with the nRF5340.

I want to drive multiple GPIO pins at the same time using the function gpio_port_set_masked(), but I can't understand what is the port argument that I need to pass to it.

I want to set PIN 10, 11, 12 and 13 to 0, so I was thinking to use

gpio_port_set_masked(TODO, 0b1111 << 9, 0);

But I can't find any reference on what to pass in TODO.

What do I have to define in the devicetree? What and how should I call in the main.c of the application?

Any help is appreciated. 

Thanks

Hi, apologies for the late response

For P0.XX pins, add this at the top of the source file:

static const struct device *gpio0 = DEVICE_DT_GET(DT_NODELABEL(gpio0));

Then replace TODO with gpio0. The rest looks good.

Do the same with gpio1 for P1.XX pins.

Thanks, Oivind,

I was using DEVICE_DT_GET(DT_N_NODELABEL_gpio1) in the end but I appreciate your answer, seems much more elegant!
