The class EOSEventHandlers provides an OnObjectCreated event, which is triggered when the camera is done writing a captured image.

virtual void OnObjectCreated(const EOSEvent *evt, uint8_t* buf) = 0;

The event itself triggers fine, but how do I retrieve the filename of the written image? The buf doesn't seem to be a simple char* as I first thought.

The EOSEventMonitor example contains a custom parser made to extract a filename from EOS 'Object Created' event, as a source comment states. Running this example does indeed result in the filename being retrieved. Unfortunately, I don't see how I could integrate this code into my code.

If anyone could shed light on how this is done or point me in the right direction, I would greatly appreciate it. Thanks!

I saw that it was mentioned in some of the Demo's that the PTP examples can capture an image and through the serial terminal return a filename of the image captured.

I had a look and have not been able to find this, is it possible to present an example that does a capture and also returns the captured filename? (I use Nikon, but a generic example would be great).

In underlying PTP::Transaction there is an if checking for *params not being zero before calculating len. There is at least one PTP Command that needs the first parameter to be zero (0x90c2=Nikon ChangeCameraMode)

Why is there the check for *params? Removing it would solve the issue.

I'm getting problems compiling the examples (i've tryed two eos examples).
The error message is:

When compiling sample code using any recent version of Arduino IDE compiler throws numeros errors like this one: "/Users/username/Documents/Arduino/libraries/PTP_20/ptpconstitles.h:166: error: msgPlayback_Rate causes a section type conflict"

Can the pull request be accepted, it seems to work and correct the issues?
Many thanks!

Hello,
i'd like to build an arduino controller for a Fujifilm finepix jv100 point and shoot machine.

Would this library work with this kind of cameras?

Sorry for asking, but i'd like to know before testing to avoid breaking something...

Thanks!

Hi !
First, thanks for what you did !
I'm trying to build the ptp device info example, but I have a problem. here is the error :

USB_Host_Shield_2.0-master/settings.h:139:176: fatal error: SPI.h: No such file or directory
 #include <SPI.h> // Use the Arduino SPI library for the Arduino Due, RedBearLab nRF51822, Intel Galileo 1 & 2, Intel Edison or if the SPI library with transaction is available 

I don't know why this, because, all example of the usb host lib worked perfectly and they use SPI.h

If anybody could help me, it would be great.

thanks in avance !

( Sorry for my bad english, I'm french )

Hi, i can't run any sketches from the PTP_20 library. I tried using Arduino Ide 1.0.2, 1.0.5, 1.5.6, 0.2.2...

For example, from the PTPDevInfo sketch I get a lot of "*** causes a section type conflict", and from the EOSCapture sketch I get a lot of error like ".../usbhost.h:21:2: error: #error "Never include usbhost.h directly; include Usb.h instead", and from NKRemote sketch I get same error from EOSCapture plus some type and scope error.

There's anything you can tell me to do in order to make this library work correctly?

Thanks
