Why is it unsigned int? Is your camera depth 32 bits per pixel?

it's 16 bits
i think i'm lost here
will try with unsigned short

Please try to put your driver somewhere like Github so at least we can see the code and could comment on it.

okay, let's go :
the original project is here : astroccd.org/
and there is this really long thread :
www.cloudynights.com/topic/497530-diy-as...t-color-6mpx-camera/
it's a DIY CCD Camera based on Nikon D40/50/70 CCD chip
It works really well.
But : for now, the code is written in Delphi, and works with ASCOM pilots
i'm just trying to translate in C the Delphi library found here :
github.com/vakulenko/CAM8_software

So, here is my attempt :
github.com/gehelem/indi_cam84_ccd

for the record :
my ugly driver is working now, anyone interested ?
(this cam84 is really an interesting project, now followed by a new version Cam86)
Gilles.

Great news! Can you write a detailed article on it so we can publish? I'm sure there are some out there who love DIY solutions!

Of course with pleasure, (tell me how)
But first i'll need a few more weeks to clean and improve my code :
-framing not tested
-binning not tested
-need to understand how to render bayer matrix
-real sky tests !
I also want to test on raspberry, Odroic C2 & XU4 (i have one of each) :
The use of FTDI D2XX driver forces to unload modules ftdi_sio and usbserial, which prevents to use the majority of USB serial converters...
This is a big disadvantage we can solve chaining indi servers
Gilles.

Yes please have your driver somewhat production-ready first and the FTDI problem is a show stopper for most users since it would break their device connections, so try to figure out a clean solution.

One step forward :
I've updated the code to use libftdi instead of D2XX -> now i can keep the usage of serial adapters
One step backward :
i have now troubles to synchronise writes and reads of ft2232 with libftdi, images are degraded
i think timings ar different between D2XX and libftdi, i have to investigate...
