for example mapping all the 16 gpio pins of a stm32 in my own `app.overlay`
will look something like this
/ {;
gpio_1: gpio_1 {
compatible = “gpio-keys”;
gpios =
label = ” GPIO no 1″;
};
};
/ {
zephyr,user {
pa0-gpios = <&gpioa 0 GPIO_ACTIVE_HIGH>;
pa1-gpios = <&gpioa 1 GPIO_ACTIVE_HIGH>;
};
};
I did it like this
you will need to add a compatible
it is working without that
I don’t know how
but to make this work i have to keep this convention `name-gpios`
its basically superimposing on the existing GPIO
think so
I am trying now to read the device tree documentation of zephyr
