How long could it be to develop comedi drivers ?
patrick N
I'm Patrick, a C developper, and i've recently joining a company which
manufacture data acquisition boards (and i'm french).
So i'm considering using comedi to provide linux driver for the
boards.
So, here's my questions :
* Did the drivers i'll write will automatically be under GNU licence ?
* Considering, 1) i've never developped drivers for linux (just read
some about it) but in counter part i've already Microsoft drivers
written, can you give my a very large guess about the time it will
take to wrote down some comedi ones ?
* Did you notice the wiki page of comedi is broke ?
Thank's !

Unforutnately, I can't answer the development or wiki questions.
However, comedi (and the Linux kernel of which comedi is now a part) are GPL.
You would find it very difficult indeed to make legal, comedi-derived linux
drivers that are not GPL.
Assuming the aim is to increase card sales on linux, I think comedi is
certainly the certainly the best (only?) choice - you would get your drivers
delivered directly in the standard kernel. That is hugely attractive for
users. In contrast, you might find it difficult to "upstream" drivers that are
not part of an existing framework. As part of comedi and the kernel, you may
also be able to share some of the maintenance burden.
What kind of acquisition hardware is it? There are a couple of types of
hardware that are not so well represented in comedi: usb cards and decent
multifunction cards. I for one would certainly be interested in such hardware
if comedi drivers were available.
Best wishes,

Except the USBDUX, of course (apologies to Bernd). I mentioned USB because
people were recently inquiring about support for the NI USB cards.
The main lack is higher-performace multifunction hardware, USB or not.
