itifg-tech — technical issues dealing with this driver

[Itifg-tech] About kernel 2.6.29.6

[Krys L. <kry...@gm...>]

Hello everybody,

... or nobody. The last email has been posted two years ago and more. I 
hope to get an answer.

For my thesis I have to use a Dalsa camera (CA-D8) and I want to control 
it via my C++ code. Actually I need just only to take capture with the 
camera. Thus, I found your driver and now I try to install it on my 
linux pc. I downloaded the last version (8.4.0) but I can not compile 
it. I first get many error message about missing headers files. I solved 
this problem by setting the environnement CPATH. A this step no missing 
file but many variables (PTE_MASK, SA_SHIRQ, SA_INTERRUPT, ...) are not 
declared. I guess that the driver version is not compatible with my 
kernel version (2.6.29.6).

Will a new version of your driver be coming soon or has the project been 
stopped definitely ?

Thank you.

Christophe Libbrecht

Re: [Itifg-tech] need help configure shutter

[<M....@go...>]

Hello,

little bit late answer, but better late than never :-)

There is definitely no image (or not the whole image) read in.
Perhaps extending the first sleep a bit (0.04 is less)?
Can You send me the whole output in /var/log/messages.

Sorry, no further idea at the moment :-(

                              matthias

Dear MStein,

I did the following debugging process,

[root@203 itifg-7.2.1]# /sbin/rmmod itifg

[root@203 itifg-7.2.1]# /sbin/insmod ./itifg_g.o

then i ran my code for the shutter,

while(input(-1)==""){
image_par(1,"send","0x82 0x88"); # setting CCD to external trigger mode
image_par(0,"run");
p "test";
image_par(1,"send","0x82 0x89"); # sending trigger signal using serial port

#image_par(0,"run");
sleep(0.04);
p "test1";
image_get(0,image);
sleep(1);
}

This is the output at terminal

this is in itifgIoctl.c

this is in itifgMain.c. I think line 1003 is a hot canidate.

Yes, this is what I ask You before. If You remove the normal driver
with 'rmmod itifg' and insert the debugging one with 'insmod ./itifg_g.o'
You can see more debugging output in /var/log/messages.

The comment above line 1003 says, that the last operation hasn't finished
yet, perhaps You (or the shutter) are to fast/slow/unsynchronized?

I think this don't fix the error, it makes it only more difficult to
find.

See above and let us again try to load the debugging module!

I'm back at Monday, we have a spare day here.

Re: [Itifg-tech] need help configure shutter

[<M....@go...>]

Hello,

I think, now You should see an valid image (live video), because the
repetiting
output of test_itifg is "-0." instead of "0." before!?

The questions dealing with FOURC and 'busy timers' I can't answer, because
I don't know, what FOURC is. It is NOT my software.

Re: [Itifg-tech] need help configure shutter

[<M....@go...>]

Hello,

if You want to have 12bit out of the camera, You have to download
the right fpga-file by hand. The automatically downloaded is 8bit
only.

please try

./config_pcdig p2b1tn00.exo

OR IF THIS DON'T WORK

./config_pcdig -b0 -d 16

and run the test_itifg program again.

Alternatively, You can also advise test_itifg to use only 8bit (-d 8).

[Itifg-tech] Fw: need help configure shutter

[<M....@go...>]

Hello,

why insmod ./itifg8_g.o don't work!?

Please go the complete steps in README:

make config
make depend
make
MAKEDEV.itifg
insmod itifg_g.o

and send me the terminal output.

The 'try to transfer invalid..' means, that date from the
camera are read in, but the format seems to be misaligned.

By the way, what is Your 'uname -a' output?

                              matthias

There are:

O_RDONLY; O_WRONLY; O_RDWR: self describing
O_EXCL: only ONE can open the device at a time
O_NONBLOCK: don't block the read call till next frame
O_APPEND: don't use only one buffer; 'append to the current'
O_SYNC: keep the device synchronized to frames (blocks). For the
        dma device it means: start the dma right when the frame
        arises in on-board memory (this is what you usually expect,
        but if YOu want, You can start the dma when You want).
        For the exs device it means: if You write a new shutter time,
        update the shutter AFTER the whole frame is done (if You don't
        do this, Your frame can be broken)
O_DIRECT: no used

The is a fundamental difference:

1. lseek +LONG_MAX: grab mode

You are interested always in the MOST RECENT frame. If You have a longer
processing and there are other frames arrived in the meantime, they are
dropped. The Acquisition is forever.
test_itifg -c (contig) mode

2. lseek n*paged_size: snap mode

You are interested in ALL frames. If You have a longer processing and
there are other frames arrived in the mean time, You get always the
next frame, not cared how 'old' the frame is. You have to count the
number of acquisitions.

NOTICE: If You are on-time with Your processing (display, save,
calculations)
        there is no difference, but if not...

We usually use the grab mode for user live image display (including some
easy on-time calculations) and the snap mode for measuring series.

Oh dear, You are right!!!

The overflow calcualtion here is (itifgBuf.c:buf_int_overflow()):

  if (buf->present + buf->isize == LOFF_MAX ||
      buf->present + (iti_loff_t)buf->isize < buf->present)
    {
      iti_loff_t offset = (iti_loff_t)1 << (sizeof(iti_loff_t) * 8 -2);

      buf->present -= offset, buf->current -= offset;
      overflow = TRUE;
    }

which isn't aligned to buf->isize (item_size: frame size here). :-(

Please try a offset %= paged_size; for now (this is, what we do).
I have to fix it!

Since we only use 64bit, the overflow isn't as much.

1./2.)
Yes, the idea behind it is a producer/consumer with a read and write
pointer.

3.)
This differs in grab/snap mode (see above)!.

Re: [Itifg-tech] need help configure shutter

[<M....@go...>]

Hallo,

so lets try to fix it...

At first I need mode debugging output. Please load the debugging
module (as root):

      rmmod itifg
      modprobe itifg_g

Then please run TWO acquisition cycle of Your program and send
me the output in /var/log/messages.

The interesting lines are those which contains 'itifg'. Please cut it,
because
the file is usually a bigger one.

Hope, the statements are right, because 7.2.1 is rather old...

                                    matthias

Ah that worked for me, thanks. I noticed you used those flags in  
test_itifg, but it never occurred to me that those flags were that  
important.

Now that O_APPEND seems to influence the drivers behaviour quite a  
bit, are there other flags that are important? I see you also use  
O_SYNC which supposedly explicitly synchronizes the read/write calls  
in memory, blocking until the call is complete. Is this also necessary?

I also noticed by running test_itifg through strace and varying the  
size of the buffer (-n) and the number of frames captured (-t) that  
you do *not* use lseek(fd, +LONG_MAX, SEEK_END), but instead do  
something like lseek(fd, bufsize, SEEK_END). It appears that this  
gives new frames until 'bufsize' bytes are transferred, after which  
you restart the cycle by calling lseek(fd, bufsize, SEEK_END) again.  
How does this approach differ from lseek(fd, +LONG_MAX, SEEK_END), is  
there a lot of overhead in restarting such a cycle and in what  
situations would you recommend one of the two approaches?

Also, when I'm using +LONG_MAX to start capture, I notice that the  
values returned by SEEK_END and SEEK_CUR keep increasing with  
pagedsize every frame. Since the camera I'm using runs at about 1000  
fps, and pagedsize is 68 kb, this means that in about 31k frames,  
LONG_MAX bytes get transferred.

I notice this happens at frame 30839 for me, and the return value  
shifts back:
frame: 30835, seek_end returns: 2147172352, seek_cur returns: 2147172352
i: 30836, end: 2147241984, cur: 2147241984
i: 30837, end: 2147311616, cur: 2147311616
i: 30838, end: 2147381248, cur: 2147381248
i: 30839, end: 2147450880, cur: 2147450880
i: 30840, end: 1073778688, cur: 1073778688
i: 30841, end: 1073848320, cur: 1073848320
i: 30842, end: 1073917952, cur: 1073917952

while 2147450880/pagedsize == 32 768, 1073778688/pagedsize == 15  
420.7647, which is not an integer number. How does this influence the  
general operation of itifg and how should I take care of these events?

Also, is it correct that:
- the return value of lseek(fd, 0, SEEK_END) is the address where the  
next byte read from the grabber will be written, meaning that the  
newest byte in memory is located at the return value - 1?
- the return value of lseek(fd, 0, SEEK_CUR) is the address where the  
user needs to read next, i.e. the address up to which the user has  
processed data?
- the difference between the return values is the amount of new data  
waiting in the buffer for processing? In the test program this value  
is always equal to pagedsize, but will this increase to n*pagedsize if  
the program cannot keep up with the camera and the buffer starts  
filling up?

Ok, so the 80ms is an empirical value, you know the readout time of  
the vossk-ccd1300b camera yourself. I've also found the dalsa camera  
manual now which makes things a bit clearer. I haven't tried  
triggering exposures myself yet, but it's something I'll try when I  
have time.

Again, thanks :)

Perhaps You don't have specified the O_APPEND flag to open(2)!? You can
also set it later by fcntl(2). If this flag isn't set, only one and the
same buffer is filled all the time. Sorry, I have forget to mention it.

No no, EXSYNC and PRI are two independed outputs at the PCDig's connector.
Most times the camera only needs one input: EXSYNC. As far as I know, only
Dalsa's line scan cameras needs additional PRI Signal.

You don't see the 80ms readout not directy, You only see it indirectly:
120ms - 40ms = 80ms.
Means If You want 40ms Exposure and You know, that Your camera have a
readout of 80ms, You can't go with Your cycle time below 40ms + 80ms =
120ms.
Take care of a litte safety time of 1ms => 121ms.

REMARK: Recent cameras can expose a new image WHILE sending out the former
        image. With this cameras You can shrinken the cycle time more and
        more, till You reach the readout time.

The driver appears to do what I want now, although I again have some  
questions.

Again, I init my mmap with size 4*pagedsize. I configure the camera,  
start grabbing by calling lseek(fd, +LONG_MAX, SEEK_END), do some  
stuff and stop by calling lseek(fd, -LONG_MAX, SEEK_END). So far so  
good.

When I try a lseek(fd, 0, SEEK_END), process image, lseek(fd,  
pagedsize, SEEK_CUR) cycle, everything works as expected. Select  
blocks until a new frame arrives, and the mmap'ed memory holds a new  
frame every time. I do this without using the return value of the  
lseek calls at all.

What I find a little odd though, is that my new image is always at the  
beginning of my mmap'ed memory, and the rest of the buffer seems  
empty. Even if I do not call SEEK_CUR afterwards and thus not tell the  
driver that I'm ready, I do not see the buffer fill up.

SEEK_END *does* return values that keep increasing, like 69632 the  
first time (pagedsize), 5849088 (84*pagedsize), etc. The image located  
at the beginning of the buffer is overwritten every time, but I do not  
see images in the rest of the buffer.

Could you explain why every new image is at the beginning of the  
mmap'ed memory and why the rest remains empty? And do I need to use  
the output of the lseek() calls at all, or are these merely necessary  
to signal the driver I want to do something? It seems to me I can  
always use the data in the beginning of the buffer, and do not need to  
move my pointer at all.

Oh sorry, I overlooked that. It's a bit clearer, thanks. As for the  
vossk-ccd1300b-12bpp-pcd.cam
file, I see that
  EXT_SYNC_PERIOD_TIME = 121000.000
sets the complete cycle time, and that either
  EXSYNC_MIDPOINT_DELAY = 40000.000
or
  PRI_MIDPOINT_DELAY = 40000.000
set the exposure time (or both?), but I do not see the readout time of  
80 ms anywhere. 2x40ms = 80ms, but I assume that the values that  
control the exposure time do not set the readout time. Could you  
explain this?

Thanks again for your time,

When You are doing a normal blocking read with page_size, it is easy
for You and the driver. The call blocks until a new frame has arrived
an then the frame is copied out. If You call read the next time, You
block and read the next frame.

With select/mmap the things get more difficult:

1. How to wait for a new frame? -> with select, You have done this.

2. How to get the information, at with offset into Your mmap space
   the most recent frame resides, at 0 * page_size, 1* page_size,
   2 * page_size, 3 * page_size (assuming mmap size is 4 frames).

   This is done by lseek 0 SEEK_END

3. You have to tell the driver, that You have read/accepted the frame.
   This is important for Your problem, thar select always signals
   incoming data.

   This is done by lseek paged_size SEEK_CUR

The lseek interface is as follows

SEEK_END refers to the producer (the device driver that generated frames)
SEEK_CUR refers to the consumer (You)

offset == 0 means: don't change anything, query the current value
offset != 0 means: adjust somthing (paged_size based)

Please read the man/extime_itifg.txt manpage, it seems to be up-to-date
an describes it a little bit. Further You should have a look at
conffiles/vossk-ccd1300b-12bpp-pcd.cam. The values into this file are
setup for a free running mode with fps = 1/121ms and an exposure time
of 40ms (readout is 80ms, safety is 1ms)

If You have setup the camera in a manner, that it needs a trigger
input (edge) to make images and/or a shutter input (level) to control
the exposure time You have to use the exs device.

I've been trying this but there are a few things that don't work, or  
at least not as I expected it to work.

Opening the board(/dev/ic0dma) and configuring it works without a  
problem as far as I can tell. Starting the camera with lseek +LONG_MAX  
works, but then I run into some problems.

My test program opens the device, reads configuration from the FG,  
reads the .cam file, sets the configuration, and then gets several  
camera variables (width, height, decimation etc). Finally I set the FD  
to nonblocking. After configuring the FG board I setup my mmap buffer.  
I reserve 4 * PAGEDSIZE bytes, giving me space for 4 frames. If I'm  
correct this procedure more or less mimics test_itifg.

First of all, select() does not seem to block until an image is ready,  
it returns immediately with return code 1, i.e. one FD would be ready  
for reading. When I run `lseek(cam->fd, 0, SEEK_CUR);` after that  
however, it returns 0, implying that nothing happend. Also the image I  
read out is the same every time lseek returns 0.

Second, I do not exactly know what to do with the lseek return value.  
In my test program I ran select() followed by lseek() several times,  
the first times lseek returned 0 and the images were identical. After  
a while, there appeared to be a new image as lseek returned exactly  
PAGEDSIZE, and the image I read out was different. However, I did not  
change my mmap'ed pointer at all, it was still pointing to the  
beginning of the mmap buffer. Another thing that I noticed is that  
lseek does not wrap, the values it returns can be anything, sometimes  
several times the mmap size.

The questions I have are:

- Do you know why select() does not block?

- What does lseek SEEK_CUR return, and what should I do with that? Do  
I need to adjust a pointer to the mmap'ed area myself, or is the mmap  
window modified by the driver?

- I noticed in test_itifg that you lseek with `int whence` set to  
SEEK_END with offset 0 several times as well. What does this do  
exactly, and do I need that?

- If I'm correct the data beyond the frame itself (after RAWSIZE)  
holds a iti_info_t struct. However, although I can read out the  
timestamp, I cannot read out the frames captures or lost, do you know  
how  to do this correctly? The methods I use is (after SEEK_CUR):

	buf->info = (iti_info_t *)((char *)buf->data + cam->rawsize);
	struct timeval timestamp; // copying unnecessary, I know
	memcpy (&timestamp, &(buf->info->acq.timestamp), sizeof(struct  
timeval));

after this, I would assume that buf->info->acq.captured and buf->info- 
 >acq.lost would hold the captured and lost images, however their  
values are 0. (int) timestamp.tv_sec does appear to work however, so I  
assume I'm reading the right part of memory. How can I get the frames  
captured and/or lost?

I would like to set the camera runmethod (if I'm correct this is set  
with 'EXSYNC_MODE = EXSYNC_FREE_RUNNING'), what modes are available?

Also I would like to set the framerate and exposure time  
independently. There are multiple timings however, and I do not know  
which times the various parameters control. I noticed that  
EXT_SYNC_TIME appears to be rejected by test_itifg, when I uncomment  
the line '#EXT_SYNC_TIME = 572.000   # us (140ns ... 572us)',  
test_itifg tells me 'parse error line 24: EXT_SYNC_TIME = (null)',  
when setting it to 'EXT_SYNC_TIME = 0.572000' I get a segfault.

Furthermore, I noticed that EXT_SYNC_PERIOD_TIME must be longer than  
PRI_MIDPOINT_DELAY, is it correct that the first controls the  
framerate (period) and the other the exposure time or something?

In short: what do the timings mean? I'm using the PCDIG board in  
combination with a dalsa CA-D6 camera.

With respect to the above questions, how/when is the exs device  
relevant?

Also, I noticed a typo/error in pcdigIface.c. It statically fills a  
struct for setting a board to default config, which goes like:

  96                 /* next both values are adjusted by the fpga  
download!!! */
  97                 8,              /* most used pixel size */
  98                 PCD_1CHAN_L2R,  /* standard geometry */
  99                 PCD_DISABLE     /* non-interlaced is standard */

However, the struct is declared in itifgExt.h as:

714   int geometry; /* this we need to load the source scatter gather  
right */
715   int pixelsize; /* this value we need to load the lookup tables  
right */
716   int interlaced; /* we have to collect even and odd frame for one  
image */
717 };

suggestiong that line 97 and 98 are swapped in pcdigIface.c

Another thing that I found was that test_itifg does not accept mmap'ed  
mode, after calling

1596     if (ioctl (devdesc, GIOC_SET_CAMCNF, &camcnf) < 0)

it says

1602     if (args->other[args->other_i])
1603       Clean_Up (EXIT_SUCCESS);

which quites mmap mode immediately without capturing frames. Is that  
correct?

Again thanks for your time and help,

Tim

Hello Tim,

sorry, You don't have overseen any documentation, because there is no

that is 'up-to-date' :-(

There are two basic operation modes:

1. The 'grab' mode
   You only want to have one image at a time and You want to have the
   most recent image. You don't care, if there are images lost, when
   You process one.
   Often used for live video and quick processing.

      call sequence:
      open
      mmap ringbuffer size (min 2 images)
      ioctl GET_CAMCNF
      modify via iti_read_config
      ioctl SET_CAMCNF
      ioctl GET_RAW|PAGED_SIZE
      lseek +LONG_MAX SEEK_END

loop:
      wait for image (poll/select/signal)
      lseek 0 SEEK_CUR to get the offset of the current image into Your
memory
      Image Processing

      lseek -LONG_MAX SEEK_END
      munmap
      close

2. The 'snap' mode
   You are interested in EVERY image you can get. No image should be
   lost. The number of images is limited by the main memory You have.

   same call sequence except:
      no mmap/munmap
      lseek number_of_bytes_to_read SEEK_END
   into the loop:
      only read - it is blockin till a new image is there

When working in grab mode - mmap makes sense, in snap mode - read is
the better solution.

>   - What is the difference between the /dev/ic0??? descriptors? when
> are they used?

There are cfg, acq, dma, exs, lut, iop.

cfg - FPGA download
acq - camera to board acquisition
dma - on-board memory to host memory transfer
exs - trigger/shutter/exposure handling
lut - on-board lookup table handling
iop - on-board i/o ports

For common image acqustion usage, You never use acq directly! You open
dma instead and if acq isn't open at this moment, dma couples acq
internally.

to start an image acquisition, You have to do

grab mode: lseek +LONG_MAX SEEK_END

snap mode: lseek number_of_images * number_of_bytes_per_image SEEK_END

to stop acqusition, you alwas do

lseek -LONG_MAX SEEK_END

For the grab mode you need some additional calls lseek SEEK_CUR/SEEK_END
to get the offset of the most recent image/to confirm this image

>   - What do the various parameters in the .cam files mean?

You setup the board for a specific camera. The parameters are different
for the different boards and different cameras. There are some more
exapmles into the conffiles dir and some of the parameters are self
explaining. If You are unsure ask me for the behavior of a a specific
switch.

There can be various operation modes for one camera. One of the most
important choise it weather the camera makes images from itself (free-
running mode) or it is controlled by the board (trigger and/or exposure
time). Then the exs device gets involved.

There is a function iti_parse_info, that reads /proc/itifg8 and fills
You a 'setup' structure, You can the it from that. Other approach:
You tell me Your board an I tell You the number.

Sorry to be short at some points, the time...

Happy Easter! (I'm back next Tuesday)

[Itifg-tech] Camera readout using itifg 8.4

[Tim v. W. <T.I...@ph...>]

Hi again Mattias,

I'm trying to get a camera (dalsa cad6 256x256) to run with the itifg  
driver. It works with the test_itifg routine supplied with the driver  
after you helped my figure out how to tell the driver to use a  
specific .exo file (thanks again). I'm now trying to write my own  
routine which reads out the camera such that I can incorporate it in  
my program. There are however a few things that I have some difficulty  
finding out, and I hoped that you could help me. I've looked through  
the documentation supplied with itifg 8.4.0 (which is the version I'm  
using), but this seems rather old, and browsing through the changelog  
is unclear at best.

The things I'm trying to find out are:
  - What is the normal mode of operation to get a camera to run,  
specifically the (fast) mmap mode? What ioctl calls are needed in what  
order?
  - What is the difference between the /dev/ic0??? descriptors? when  
are they used?
  - How do I start and stop the framegrabber? The changelog mentions  
lseek() ('ioctls STRT/STOP replaced by one lseek interface'), where  
and how can I use that with itifg?
  - What do the various parameters in the .cam files mean?
  - Are all camera specific settings in the .cam files or do I need to  
do some things myself? I.e.: do certain cameras require a different  
mode of operation, or is this all the same for all cameras?

And more specifically:
  - How do I find out the module that I need to use with  
iti_read_config() (fourth argument)? I currently use 48, but I don't  
know why (this is what itifg_test uses).

If I overlooked certain documentation, please tell me. Also, if these  
questions are too general for the itifg driver, let me know. However I  
could not find the answer to these questions (easily). An alternative  
would be to take your test code and cut out the parts I need, but  
that's a rather hacky approach in which case I wouldn't fully  
understand what I would be doing.

Thanks in advance,

Re: [Itifg-tech] itifg-8.4.0-0 released

[<M....@go...>]

Hello Fabien,

I think, I have found it:

the access to dma1stfld/dma2ndfld fails, they are allocated at the end of
icpciIface.c

  if (!brdif->brd.i->dma1stfld)
    {
      brdif->brd.i->dma1stfld =
      (off_t*)iti_malloc (brdif->brd.i->osp, CR_FCNT_MAX * sizeof(off_t),
                      "dma 1st");
      if (!brdif->brd.i->dma1stfld) return -ENOMEM;
      iti_memset (brdif->brd.i->dma1stfld, 0, CR_FCNT_MAX * sizeof(off_t));
    }
  if (!brdif->brd.i->dma2ndfld)
    {
      brdif->brd.i->dma2ndfld =
      (off_t*)iti_malloc (brdif->brd.i->osp, CR_FCNT_MAX * sizeof(off_t),
                      "dma 2nd");
      if (!brdif->brd.i->dma2ndfld) return -ENOMEM;
      iti_memset (brdif->brd.i->dma2ndfld, 0, CR_FCNT_MAX * sizeof(off_t));
    }

CR_FCNT_MAX is defined in icpciReg.h as

#define CR_FCNT_MAX           CR_FCNT_MASK >> CR_FCNT_SHIFT

For the allocation size we get a line

CR_FCNT_MASK >> CR_FCNT_SHIFT *  sizeof(off_t)

which is wrong, because the '*' binds tighter than '>>'

Please change the definition of CR_FCNT_MAX to:

#define CR_FCNT_MAX           (CR_FCNT_MASK >> CR_FCNT_SHIFT)

Good Luck!

                                          matthias

I have just added an other printf like:

   for (frame = 0; frame < frames; frame++)
     {
       ITI_PRINT1(brd->i->osp, "  frame: %d\n", frame);
       iti_printd (brd->i->osp, "D\n");

Hello Fabien,

this is a correct output, icp_src_init runs correctly and and image
is acquired!

And now the output including the icp_src_init ABC... printouts with
the new (crashing 8.4.0-0) version!?

Re: [Itifg-tech] itifg-8.4.0-0 released

[Fabien S. <fsp...@ir...>]

I have just added an other printf like:

   for (frame = 0; frame < frames; frame++)
     {
       ITI_PRINT1(brd->i->osp, "  frame: %d\n", frame);
       iti_printd (brd->i->osp, "D\n");

dmesg gives

Hello Fabien,

the crash is somehere in src/board/icpcoIface.c:icp_src_init().
I have added some debug output, that we can see more:

static int

  if ((error = cr_set_pitch (brd->i, fmt->line_size)))

  for (frame = 0; frame < frames; frame++)
    {
      iti_printd (brd->i->osp, "D\n");
      brd->i->dma1stfld[frame] = brd->i->dma2ndfld[frame] =
        base + frame * fmt->frame_size;
      iti_printd (brd->i->osp, "E\n");

            return -EIO;
          }
        iti_printd (brd->i->osp, "J\n");
        }

      iti_printd (brd->i->osp, "K\n");
