I vibe coded a driver to monitor and control the temperatures and fans in my Aoostar WTR PRO. (lemmy.world)

I run OmniOS on an Aoostar WTR PRO as my NAS and for most of my self hosting needs. After installing a new fan, I wanted to see if I could read and control the fan speed from the OS instead of just the BIOS. Using Claude chat, I got a working kernel driver that gives me fan speed, PWM control, temperature readings, and even (incorrect) voltage readings.

I wanted to share as an example of what's currently possible. I've even seen people vibe code ethernet drivers for freeBSD.

What do you all think of using LLMs to cobble together drivers like this?

That's awesome! Can you describe your set up for vibe coding this? I'd like to take a look at porting postmarketOS linux, or ubports to some phones I have laying around.

I just used the free chat with Claude, it created and tracked the files in its own webchat thingy. Being a kernel module, I was happy to manually check, copy/paste, compile, then run the code for each iteration.

Porting postmarketOS to a phone sounds like it may require some amount of manual running and explaining results back to the chat. Ultimately the output only starts to get functional when it hits reality and needs to keep adapting to feedback.

I wrote a blog on the process that more focuses on the journey and technical details of the controller chip.
