Shell aliases

[diegoherranz]

Hi,

Is it possible to define shell aliases?
I'd like to use the GPIO shell and being able to use custom-defined names rather than the GPIO device and number.

That is, I would like to be able to run:
gpio set relay2 1
instead of:
gpio set gpio@40020800 7 1 (pin 7 of gpioc at address 40020800)

I had a look but couldn't find anything and it would be a very useful feature.

Thanks!

Hi, you can use an overlay or add this property to your gpio device tree nodes to define line names for each pin of your port like this:

https://github.com/zephyrproject-rtos/zephyr/blob/main/boards%2Farm%2Fnrf52840dk_nrf52840%2Fnrf52840dk_nrf52840.dts#L153

But at present when using the shell you still need to specify the port before the line-name. You can use tab complete to discover what line names are provided by the port once the port is specified in the shell command.

Thanks for your reply. I had missed the gpio-line-names before.
As you say, it's not perfect in the sense that I'd prefer to avoid specifying the device, but it gets much closer :)
Thanks again.
