I am new to this forum but not to OpenWRT. I have been using it several years now and have grown very fond of it.
But to my dismay, there is one part of OpenWRT that is still kind of inaccessible to many users due to the fact they are not coders but power users or network engineers. I am talking about effectively and easily controlling GPIO lines on devices with a GPIO so one can add LEDs or buttons/switches to the configuration without having to resort to having to write a patch or some modification to the kernel (I for one have no idea how to do this - I am a network engineer who happens to like to use OpenWRT for his private projects). I use different models of Raspberry Pi, including the Rpi 4B.
I would like you, fellow forum users and in particular users who would also like to have this ability, to chip in in this discussion. I will be asking many question and ultimately my goal is to have LUCI support for easy and quick control over GPIO lines. Again, I am no coder. I am hoping someone with the needed expertise will donate some time to help me with this endeavour.
Of course there already may be a solution to this, but I have scoured Google for any helpful information and any solution I could find requires one to have a fair bit of knowledge of coding.
I know there is the sysfs method but I am talking about low-latency, kernel controlled GPIO control that can be triggered in the case of an output (extra LEDs).
I think you misunderstood my OT (off topic!) comment. It's my private war against people stating that they use the project for several years and at the same time aren't able to spell its name correctly Don't take it personally.
Your post is just 14h old... be patient and don't get upset if nobody else joins the discussion.
Oh well, no harm done. I may have overreacted. The thing is I've been hunting for a way to configure GPIO leds, but mostly it meant modifying the DTS. That means i have to learn a whole subject just for one modification, time I don't have. I am a network engineer, not a software developer. I need some crucial help to get me on my way to my goal. From wulfy's hints I understand it's possible to define GPIO leds in the config.txt?
