Writing a basic Linux device driver when you know nothing about Linux drivers

> I also thought I’d message the vendor and ask them if they could share any specifications or docs regarding their protocol. To my surprise, Nanoleaf tech support responded to me within 4 hours, with a full description of the protocol that’s used both by the Desk Dock as well as their RGB strips.

How cool is that? Too many vendors still think that they have valuable intellectual property in such relative trivialities. And that handing out the specs freely helps their competitors more than themselves.

Yeah that part of the article put a big smile on my face.

I did the same thing back in college, when I was in a lab. We wanted to do some research on Wi-Fi signals, and I happened to own a bunch of Wi-Fi adaptors produced by SomeSmallTech Co. Ltd., which featured relatively new Atheros chips and didn't have Linux drivers at the time.

So I sent an email to the company's public email address, asking for some datasheets, "for science". To my disappointment, presumably a PR person replied that they "don't have a company policy to collaborate with academic research". (But they did send a quick reply, kudos to that.)

Funnily enough, years later I ended up working for said company. Naturally, when I first logged into the company network, I searched for the datasheets I asked for. There were "classified" watermarks all over the PDFs :)
