Support for K-70?

[jmozmoz]

I tried to use the command line utility (using Windows) to connect to my K-70:

c:\opt\pktriggercord>pktriggercord-cli.exe --status --debug
Debug messaging is now enabled.
pktriggercord-cli.exe 0.81.00
model (null)
device (null)
Checking drive:  C
Checking drive:  D
Checking drive:  E Checking drive:  F RICOHIMG DSC_K-70
...
camera not found

Is there any change to add support for it? Where to start?

K-70 is not yet supported. I've created a test version, please test it and copy the output here.

pktriggercord-0.84.03-win.zip

Thank you for your very fast response. The GUI version crashed on startup. This is the output from Visual Studio Debugger:

Unhandled exception at 0x76739170 (msvcrt.dll) in pktriggercord.exe: 0xC0000005: Access violation reading location 0x00000000.

If there is a handler for this exception, the program may be safely continued.

and so on...

Here is the output of the status from the command line:

I was also able to get a picture in manual and "green" mode:

c:\opt\pktriggercord-0.84.03>pktriggercord-cli --file_format=JPEG -o test.jpg -i 100  -t 2 -m M -a 4.5
c:\opt\pktriggercord-0.84.03>pktriggercord-cli --file_format=JPEG -o test1.jpg -m GREEN

So actually, everything I need is there 😄 👏 👍
(ok, it would be nice to have all this status infos, but as everything is in the exif data of the picture, it is not so important)

[asalamon74]

Looks promising. I attach a new version which tries to parse the status info. Please try the following command:

pktriggercord-cli.exe --status_hex --debug

It might also fix the GUI. I'm not sure. You can also add --debug for the GUI.

The GUI does not crash (immediately) anymore. If I press "Green Button" is hangs. I can access status, focus and take picture. But it looks like pictures are not saved. At least I cannot find them.

Most of the fields look good. "af point select" is invalid, I'll fix it, because it may cause problems. Battery fields also look strange but those fields are not too important.

Green button: It is best to test the command line version first. Try to take a picture with and without --green option.

GUI save: The GUI does not save the image if you take a picture (it saves only in the camera buffer). You can save it using the save as button. Or alternatively you can turn on auto save and add specify the prefix of the filename.

The second version you send me seems to include some regression: With the first version I could take pictures and transfer them to the computer. With the second version, the (command line) program hangs and only a picture file with size 0 is created. I have attached two log files, _v1 was created using the first version you linked in your comment on 2016-12-13, _v2 used the second version of 2016-12-14.

So I traced down my problem (without really knowing what I am doing): The check at

pktriggercord/pslr.c

Line 909 in 0c3d8e2

if( p->model->parser_function && (bufs & (1 << bufno)) == 0) {

for bufmask results in a return from the function. The likely reason is, that the bufmask value is read from the wrong address within the status buffer (set at

pktriggercord/pslr_model.c

Line 607 in 9e0be49

status->bufmask = get_uint16_le( &buf[0x1C]);

).

If I understand the code correctly, the status buffer should contain a 1 at the correct address. By setting the bufmask address to 0x0C, it seems to work (because the value at that address is equal to 1). Is this just a coincidence? Actually, what is the meaning of the buffer mask?

[asalamon74]

There is a buffer in the camera for the images. It can store several images but no more than 16. bufmask is a 16-bit word. Each bit shows if the camera buffer is occupied/empty at that index.

Invalid bufmask reading may cause the strange regression. My first version ignored the bufmask , the second tried to read it.

Test it using bracketing. If you take 3 images using bracketing the camera stores the 3 images in the camera buffer and the program only downloads (and deletes) the images at the end. If it works than your patch is great. Send me a pull request after that. (If you don't want to do that just copy the info here, and I'll patch it).

[jmozmoz]

Ok, what if found out is: There seems to be only one buffer in the camera. If I select bracketing and take 3 or 5 pictures, I am able to store the last picture as raw file (if I selected JPEG as standard format). The other 2 (or 4) pictures seem not available.

I tried different setups and downloaded the hex-status, and nearly all the time the buffer address 0x0c contains 0x01. Only in one case, there was 0 stored. Unfortunately, I was not able to reproduce this.

Is there a known way to clear this internal buffer?

It looks like, if I remove the SD card, this buffer address contains zero, after turning on the camera. If I take one picture, it is back to 1. But this also does not work all the time.

So what to do? My suggestion would be to use 0x0c as address for the buffer.

[asalamon74]

Limiting the camera buffer size to 1 is a very strange change. Quite a few functions of the program will work even in this case, but a few advanced things (like bracketing...) will not work.

It also assumes that 0x0c is 0 at the beginning, 1 after taking an image and 0 after deleting the buffer. If 0x0c is always 1 it will not work.

Camera buffers can be deleted by the pslr_delete_buffer function.

[asalamon74]

@jmozmoz I attach a new test version which uses your patch. Someone tested the Linux/K-70 and the program deleted the SD-card. This is very strange because the program is not able to save images to the sd-card. Make a backup before testing the K-70 support.
