PTP 2.0 library function turns on Bulb mode on Nikon DSLR camera via USB

Bulb mode activation code screenshot

Bulb mode activation code screenshot


Last week my friend Hans and I spent some time in my lab exploring which features of his Nikon D300 are available via PTP protocol. Hans is working on extended range HDR-capable intervalometer and he needed to find out a way to switch his camera into bulb mode using Arduino board and USB Host shield. After we finished I realized that while bulb mode is not tricky to activate, it is not obvious either and no hints exist in the code and examples showing how to do this. This short article is intended to fill the void.

In PTP, shooting parameters, such as shutter speed, aperture, ISO, etc. are changed by setting certain device property. For each parameter there exists a list of allowed values of this property, each property value corresponding to a parameter value. For some parameters, property and parameter value lists are dynamic. For example, starting and ending aperture values are different for different lenses; additionally, the aperture step can be changed in camera settings. Stepping can also be changed for shutter speed and exposure compensation and this can also happen during PTP session if a photographer decides to switch modes – in this case a property may become unavailable, like shutter speed in aperture priority mode. Therefore, before changing a property value for one of these parameters it is necessary to somehow retrieve a list of available property values.

The property value list retrieval mechanism is slightly different for different cameras. On Canon DSLRs, a special event is generated by the camera and sent back to PTP host at the beginning of the session and also each time camera mode was changed, lens were swapped and so on. The application needs to track those events and constantly maintain current value list for each property. On Nikon DSLR, it is possible to simply get value list for a property any time it is needed. To save memory, the list is not stored but simply requested from the camera each time a property needs changing. It is combined with actual property change in two templates – StepUp and StepDown. If you need to increase, for example, shutter speed – call StepUp. If you need to decrease it, call StepDown.

If you “step up” shutter speed on Nikon DSLR manually, the last 2 values will be 30 seconds and bulb. If you step up shutter speed using StepUp method using Nkremote sketch it will stop at 30 seconds. This happens because bulb mode is not included in the list of available property values for shutter speed but simply defined as 0xffffffff. As a result, StepUp doesn’t know that another value is available. It is still possible, however, to set the property directly and I will show you how to do it.

For the demonstration, I will be modifying Nkremote sketch itself. The psconsole.cpp file contains the menu tree. The “Change Settings” menu contains transitions to menus which change a particular parameter of the camera. The last one, i.e., number nine or “FocusPoint” is not very useful for remote control so I’m going to modify this menu to activate bulb mode instead. The code of ChangeFocusAreaMenu() is as follows:

QState PSConsole::ChangeFocusAreaMenu(PSConsole *me, QEvent const *e) 
{
    switch (e->sig) 
    {
        case Q_ENTRY_SIG:
            PrintMenuTitles(UPDWN_MENU_COUNT, menuUpDown);
            PrintFocusArea();
            return Q_HANDLED();
        case MENU_SELECT_SIG: 
        {
            switch (((MenuSelectEvt*)e)->item_index)
            {
            case 0:
                return Q_TRAN(&PSConsole::ChangeSettingsMenu);
            case 2:
                StepUp<VT_FOCUSAREA>((PTP*)&Nk, NK_DPC_AutofocusArea);
                PrintFocusArea();
                return Q_HANDLED();
            case 1:
                StepDown<VT_FOCUSAREA>((PTP*)&Nk, NK_DPC_AutofocusArea);
                PrintFocusArea();
                return Q_HANDLED();
            } // switch (((MenuSelectEvt*)e)->item_index)
        } // case MENU_SELECT_SIG:
    }
    return Q_SUPER(&PSConsole::Active);
}

Cases 1 and 2 originally change the focus area. I’m commenting down StepUp() and StepDown() and inserting property change operation (lines 3 and 8). The new code will activate bulb mode if you press ’1′ or ’2′ in the terminal.

          case 2:
                //StepUp<VT_FOCUSAREA>((PTP*)&Nk, NK_DPC_AutofocusArea);
                Nk.SetDevicePropValue(0xd100, (uint32_t)0xffffffff);
                PrintFocusArea();
                return Q_HANDLED();
            case 1:
                //StepDown<VT_FOCUSAREA>((PTP*)&Nk, NK_DPC_AutofocusArea);
                Nk.SetDevicePropValue(0xd100, (uint32_t)0xffffffff);
                PrintFocusArea();
                return Q_HANDLED();

After you change Nkremote, compile it and load into Arduino board. In a terminal window, choose “Change Settings”, then “FocusPoint”. On the next screen press ’1′ or ’2′, then ’0′ to return to the previous level. Now go to “View Settings”, you should see T:Bulb near the end of the output. To change it back to normal shutter mode go to “Change Settings”, then to the “Shutter Speed”.

Now let’s talk briefly about limitations. First, the bulb mode is only available in “Manual” and “Shutter Priority” modes. In all other modes an attempt to set shutter speed to bulb will be rejected. Another rather annoying limitation is capture command, which doesn’t function in bulb mode ( most Canon DSLRs continue to execute capture when switched to bulb, manually or otherwise). Cable release will work as usual so it is still possible to make a HDR intervalometer which can switch between ‘normal’ and bulb modes – all that is necessary is a digital pin on Arduino, a transistor and a couple of resistors.

This is it for the PTP, bulb mode and Nikons. I hope the information in this article was helpful for you. Enjoy!

Oleg.

    Hi,
    Can use USB Focus Controler control NIKON camera,such as change ISO,Aperture,etc?
    If of course,Why are there not such product in the market?
    Thank you!

    Hi,

    I’m trying to keep up with you guys, some time ago (ehh… almost 2 years now) I was trying to control my EOS 20D camera via USB.
    Now I bought myself a other more up to date EOS camera and tried to pick up on things again to control this new one but so far no luck.
    I am running Arduino IDE 1.02 with libraries ‘PTP_2.0′ and ‘USB_Host_Shield_2.0′ installed on my iMac Mountain Lion.
    I’ve also installed QP for Arduino v4.5.02.
    Should the examples compile without any other library or settings?
    I feel somehow silly that after a day of trying, going backwards and forwards, I can’t get most of the examples to compile, what am I missing?

    cheers,
    John

    Hi Oleg,

    I am able to compile PTPDevInfo and this works beautifully with my USB shield and my EOS/Powershot camera’s.
    (your original shield ‘v1′ that I modified it and after I ordered a new one yesterday in your shop).
    I also tried a fresh installation of the Arduino IDE on a clean/virgin OSX computer with only the libraries installed that where necessary like PTP_2.0, USB_Host_v2.0, QP for Arduino (this one installed in the Arduino.app library) and some other basic libraries.
    But the more advanced programs like EOS camera remote it struggles and doesn’t want to compile.
    Can there be things left that I’m missing?

    Cheers,
    John

    BTW; Am I correct that the biggest change from V1 to v2 hardware is cutting GPX connection and tying MRST to the USB controller from the reset of the Arduino. By doing this the hardware seems to be working and also the one that I have from Sparkfun works with this mod.

    • John

      This is the first error message during compilation;

      EOSCamController.pde: In member function ‘virtual void CamStateHandlers::OnDeviceInitializedState(PTP*)’:
      EOSCamController:536: error: cannot declare variable ‘hnd’ to be of abstract type ‘EosEventHandlers’

      -John

      • I believe it has something to do with IDE version. I’m using 1.0 – try with this version ans see if it makes any difference.

        • John

          Similar error in the same area;

          EOSCamController.cpp: In member function ‘virtual void CamStateHandlers::OnDeviceInitializedState(PTP*)’:
          EOSCamController.pde:-1: error: cannot declare variable ‘hnd’ to be of abstract type ‘EosEventHandlers’

          • This is strange; I need to take a look into this, give me couple of days.

          • Alex

            The problem is that there is one more event handler was added to EOSEventHandler class in the PTP library, but the EOSCamController sample sketch has not been changed since. It is going to be fixed in the next release of the library. Add line:
            virtual void OnObjectCreated(const EOSEvent *evt) {};
            to eoseventhandler.h file found in EOSCamController folder to make it running.

            Hi Oleg en Alex,

            Getting there…
            I’ve edited the extra line in and now it compiles a lot further then before but it ends with this error;

            core.a(new.cpp.o): In function `operator delete(void*)’:
            X:\arduino-1.0.2\hardware\arduino\cores\arduino/new.cpp:10: multiple definition of `operator delete(void*)’
            QP\qp_port.cpp.o:\\Neelix2\Users\john\My Documents\Arduino\libraries\QP/qp_port.cpp:49: first defined here

            I’ve tried Arduino v1.0 / v1.0.2 and QP v4.3.00 / v4.5.02 and combinations of both.
            Which version of QP should I stick with anyway?
            QP v4.3.00 gave me the result above in both Arduino versions.

            Cheers!

  • ysw925

    Hello,Oleg
    If I want to do some experiments of USB control NIKON camera D90,I should use what library?
    In my opinion should use “felis-USB_Host_Shield_2.0-2be3f61″and”PTP_2.0-master”.Is right
    or wrong?Is there any other library I must want to have?
    Thanks!

  • ysw925

    Can you help me,Thanks!

  • John

    Bingo!

    I’ve added the extra line as Alex suggested and I had commented out some extra lines in the qp_port.cpp
    Now it compiles and runs with Arduino v1.0.2 and QP for Arduino v4.3.00
    ——
    // void operator delete(void *) {
    // Q_ERROR(); // this operator should never be actually called
    // }
    ——
    Thanks both for your help!

    • John, I would really appreciate you help here since at the moment I recieve no reply from Oleg.
      I’ve followed your progress and have made these changes:
      1. Replaced qp_ccp
      2. Commented out these lines in the qp_port.cpp:
      // void operator delete(void *) {
      // Q_ERROR(); // this operator should never be actually called
      // }
      3. Added the following line to eoseventhandler.h file found in EOSCamController folder:
      virtual void OnObjectCreated(const EOSEvent *evt) {};

      Now I’m able to compile all examples except EOSRemote which spits out this error log:

      EOSRemote.cpp: In member function ‘virtual void CamStateHandlers::OnDeviceInitializedState(PTP*)’:
      EOSRemote.pde:-1: error: cannot declare variable ‘hnd’ to be of abstract type ‘EosEventHandlers’
      /eoseventhandlers.h:12: note: because the following virtual functions are pure within ‘EosEventHandlers’:
      C:\Program Files (x86)\arduino-1.0.1\libraries\ptp/eoseventparser.h:37: note: virtual void EOSEventHandlers::OnObjectCreated(const EOSEvent*)

      Can you help me out with this?

  • ysw925

    Hi,
    I want to do some experiments of USB control NIKON camera D90.
    I added librarys “felis-USB_Host_Shield_2.0-2be3f61″and”PTP_2.0-master”base in Arduino v1.0.1.
    When I compile NKEventLab.pde and NKEventMonitor.pde and NKLiveView.pde are successful.
    But when I compile NKRemote.pde is unsuccessful.Because lose files such as qp_port.h,
    Is any librarys I donot add?
    Thanks!

  • ysw925

    Why nobody answer?
    waiting…

  • ysw925

    hello,all
    Let nikon camera into LiveView, What command can do it?
    Thanks!

  • Hannes

    Hi!

    I’m also struggling with this library for 2 days now.
    I’m trying to compile eosHdrCapture and tried as suggested several different verions of the arduino-ide and of the qp-library in all kinds of variants:
    Arduino-ide 1.0.1/1.0.2/1.0.3
    qp-lib: qp_arduino_4.3.00/ 4.5.02/ 4.5.03

    The best solution yet is ArduinoIDE 1.0.1 and qp 4.3.00 with qp_ports.cpp you provided at your site.

    But when I try to compile, I’m still getting errors:
    core.a(new.cpp.o): In function `operator delete(void*)’:
    [...]arduino\cores\arduino/new.cpp:10: multiple definition of `operator delete(void*)’
    [...]arduino-1.0.1\libraries\qp/qp_port.cpp:49: first defined here

    I googled around but couldn’t find a solution…

    Has anybody suggestions for what I could do?
    thanks in advance!

  • ysw925

    Oleg,
    On the basis of you librarys I succeed in making the D90 camera into the liveview mode and also MoveFocus.
    Now I have a question want to your help.When let D90 into liveview mode ,D90 display screen into a blank screen
    and D90 control panel display on “PC”. My question is D90 into liveview mode Can make display screen not into a blank screen?
    Waiting for your help,You only need to answer” Can or NO”.Thank you very much!

    • I don’t think it’s possible. I experimented with several Nikon cameras, they all turn off LCD as well as video out when switched to LiveView from a PC. So basically on Nikons you can move focus but you can’t see it.

  • ysw925

    I see ,thank you!

  • Hi Oleg,

    thank you for documenting all of the PTP commands for the Canon and Nikon cameras.

    Have you had any success switching the Canon 5D MkII or 7D into BULB mode while leaving the Mode dial in MANUAL mode. Typically this is for extended HDR work to avoid touching the camera to switch from Manual to Bulb mode when exposures over 30 seconds are required as part of the exposure range.

    I know it can be done as I use a programme called GBTimelapse which controls my 5D MkII via a usb tether and I can pretty much ignore what the mode dial is physically set to and use the software to switch modes.

    best regards and happy new year

    hi oleg,

    some time ago i baught the usb-host shield from solarbotics, it says rev 1.21.

    i’m trying to get it to run on a freeduino, mega328, externally powered, with the usbhostlib 2 (from github)
    when running the test-script, i get:

    Press RESET to restart test
    Circuits At Home 2011
    USB Host Shield Quality Control Routine
    Reading REVISION register… Die revision 03
    SPI long test. Transfers 1MB of data. Each dot is 64K
    Test failed. Value written: 01 read: 00
    Unrecoverable error – test halted!!
    0×55 pattern is transmitted via SPI
    Press RESET to restart test

    can i get the shield running?

    best regards,
    ralf.

    I having some trouble getting the EosCamcontroller to compile.
    Arduino version 1.0.3 and using arduino qp 4.3.

    I added the line virtual void OnObjectCreated(const EOSEvent *evt) {};
    to eoseventhandler.h file found in EOSCamController as described above.

    I commented out// void operator delete(void *) {
    // Q_ERROR(); // this operator should never be actually called
    // } in qp_port.cpp as noted above.

    than commented out void operator delete(void *) {
    Q_ERROR();

    now I am left with the following error messages:

    qp/qp.cpp.o: In function `QHsm::dispatch(QEvent const*)’:
    /Users/fsb/Documents/Arduino/libraries/qp/qp.cpp:235: undefined reference to `Q_onAssert’
    /Users/fsb/Documents/Arduino/libraries/qp/qp.cpp:246: undefined reference to `Q_onAssert’

    /Users/fsb/Documents/Arduino/libraries/qp/qp.cpp:134: undefined reference to `Q_onAssert’

    Obviously I am doing something stupid, any suggestions for help?

    cleaned up libraries
    Everything now compiles with IDE 1.01 and 1.03
    Only cannot load Eoscamcontroller (get avrdude stk500 error)
    so still working on my canon. However, NKremote works great with my
    Nikon D300.

    This is great Oleg, Nice work.

  • Hi,
    To all of you that have problem compiling the library. Here is a short guide I wrote on how to do so:

    These are the steps you need to do in order to compile the library:

    Download the PTP library: https://github.com/felis/PTP_2.0
    Extract and rename the folder to: PTP_20

    Download the QP library version 4.3.00: http://sourceforge.net/projects/qpc/files/QP_Arduino/4.3.00/
    Extract the QP library and navigate to the libraries/qp folder.
    Now replace the qp_port.cpp with the file found here: http://www.circuitsathome.com/chome_downloads/qp_port.cpp

    Now comment out the following function:

    void operator delete(void *) {
    Q_ERROR(); // this operator should never be actually called
    }

    Now put the files inside the “libraries/qp” folder in the root of the PTP_20 folder.

    Now open eoseventhandler.h in PTP_20/examples/Canon_EOS/EOSCamController and eoseventhandlers.h in PTP_20/examples/Canon_EOS/EOSRemote and then add the following function:

    virtual void OnObjectCreated(const EOSEvent *evt) {};

    So the class end up looking like this:

    class EosEventHandlers : public EOSEventHandlers
    {
    public:
    virtual void OnPropertyChanged(const EOSEvent *evt);
    virtual void OnAcceptedListSize(const EOSEvent *evt, const uint16_t size);
    virtual void OnPropertyValuesAccepted(const EOSEvent *evt, const uint16_t index, const uint32_t &val);
    virtual void OnObjectCreated(const EOSEvent *evt) {};
    };

    Now finally put the PTP_20 directory inside the Arduino libraries folder.
    Now you should be able to compile the library.

    • Tom K

      Thank you, Lauszus! A GODSEND. I am grateful to Oleg for the thousands of hours he has put into this project, but the lack of documentation is a serious obstacle. I keep thinking I will see even a single line comment, or a sentence somewhere. Thank you for writing this down, Lauszus.

      • Tom K

        Did not work. Was not able to compile. Errors:
        controls.h:42: error: ISO C++ forbids declaration of ‘USB’ with no type
        controls.h:42: error: expected ‘;’ before ‘*’ token
        controls.h:46: error: expected `)’ before ‘*’ token
        controls.cpp:4: error: ‘NULL’ was not declared in this scope
        controls.cpp: In member function ‘void GPInRegister::CheckControls()’:
        controls.cpp:10: error: ‘pUsb’ was not declared in this scope

        Also, the instructions are ambiguous in places. “Now put these files inside the PTP_20 directory.” Which files? The instructions seem to put the QP folder in the PTP folder. Surely that’s not right.

        I am super grateful that someone took the time to make this great hardware and software available. But without basic installation instructions, part of that excellent effort was wasted.

  • Congratulations Oleg for your works !!

    I have a question :

    It is possible to get speed, aperture, White balance settings, and set it,
    from the DSLR Nikon camera ?

    Have you an PDE sketch exemple ?

    I work on a project “Photographer Tools”, that is a color meter, exposure meter,
    flash meter, and I search a solution (Actually I create a computer Program with the SDK Nikon)
    to get and set directly the parameters mesured by my “Photographer Tools” on the DSLR.

    This is the link of my project :

    The good way for me,
    is to use a remote module (with arduino Nano for example and bluetooth or wifi connection)
    to get and set DSLR exposure values from my “Photographer Tools”.

    If you have any arduino solution ?

    Thanks for your reading.
    Regards.

  • Hi all,
    I have two little questions.
    The usb host shield V20 is compatible with the “USB Host Shield for Arduino Pro Mini” ?
    The arduino sketch “NKRemote” work with this shield and arduino pro mini ?
    It is for create a very smaller transceiver with NRF24L01 Wifi module.

    Hi,

    I’m having a bunch of trouble with PTPCapture with the new Nikon J3 (And probably other V*/J* series). Have had no problems with the software in the past and have gotten it working on other nikons ranging from Coolpix to DSLR’s.

    When hooked up, it gets to the “Camera Connected” mark, then gets stuck- no image is taken. Identical un-altered sketch runs fine on others. PTP DevInfo works fine too (attached below) and it looks to me that it should support capture image.

    Moreover, the “Image Capture” application on Mac OS is able to remotely trigger the camera without issues!

    Any ideas? Thanks!

    I’m having problems getting the more complex PTP examples to compile under PTP2.0. The simple PTP example sketches like PTPCapture and PTPDevInfo are working but I cant get the Nikon or EOS sketches to work.

    For NKRemote I get the following errors:

    NKRemote.pde: In member function ‘virtual void NKEventDump::OnEvent(const NKEvent*)’:
    NKRemote:38: error: no matching function for call to ‘PrintHex(const uint16_t&)’

    Any ideas?

    • There was a bug. Please pull the latest USB Host 2.0 and PTP 2.0 libraries, the NKRemote should now compile. Let me know if you get any other errors in the examples.

  • Lyndon

    Still have problems I’m afraid. Now I’m getting

    NKRemote.pde: In function ‘void Q_onAssert(const char*, int)’:
    NKRemote:78: error: ‘QF_INT_DISABLE’ was not declared in this scope

    I’m not seeing this function declared in qp_port.h

    I am using QP for Arduino 4.3.00 with qp_port.cpp replaced by the one from

    http://www.circuitsathome.com/chome_downloads/qp_port.cpp

  • Lyndon

    Commenting out Q_onAssert fixed it. It compiles and I see the menu on my terminal. I can do capture and print values (though these are 4 digit numbers not something immediately man readable. Anyway I will play with it and let you know if it works as expected but at least it compiles and talks to the camera.

    I tested the other 3 examples for Nikon and they all gave the same notify issue that I was seeing in nkremote so they probably need the same fix.

    Ignore my comment about Print Settings, the camera was on auto and that seems to prevent it answering. With the camera in a none auto mode print settings does give man readable information about the camera state.

    The 4 digit numbers I am seeing are steadily scrolling up the screen and seem to start with a D like “D510.” These change depending on the mode of the camera so I’m thinking it’s a debugging string..

    The sketch seems to be working as it should and will make a good starting point for my project.

    Thanks for taking time out on a holiday to debug this.

    Oleg,
    How did your friend’s Nikon HDR experiments go.? I’ve been looking at the EosHDRCapture example sketch. To what degree are the EOS and Nikon PTP functions equivalent? Could the EoSHDR sketch be used as a basis for a Nikon equivalent just by transcribing the EOS references for their Nikon equivalents or is there some complication?

    • Nikon cameras are close to Powershots; you can use the same principles but you won’t be able to directly substitute EOS commands with their Nikon equivalents.

  • Hi Oleg,
    I have a question.
    It is possible to know if the DSLR is under exposed or over exposed ?
    I use Nikon DSLR.

    Hi Oleg

    Thank you very much for this great project. I have a little Problem. Hope you can help me. I use USB Host Shield with USB and PTP2 library, connected to a CanonEOS 1100D.
    Sample code works fine with Terminal output(connected, disconnected).
    But i would not use the EOS.Capture() Function in CamState Handler (void CamStateHandlers::OnDeviceInitializedState(PTP *ptp)).

    I would use the function in the main program loop.
    How can i check in main loop if the camera is connected, disconnected or has a error?
    Does a command exist, like status=Eos.State?

    This would not work: if (Eos.StateConnected()=true){}

    Thanks for helping

    • OnDeviceInitializedState() gets called when camera is ready. If for some reason you can’t call your application directly from it allocate a global variable to signal a camera state, change it in OnDeviceInitializedState() and check it from the main loop. You’d have to do the same from other CamStateHandlers:: methods so calling the app from OnDeviceInitializedState() is preferred still.

    Hello Oleg ,
    thank you so much for such a great Library ,even through im trying to follow up with you bu i have no luck , i have used the USB library before and it works perfectly , but when i try to use the the PTP library i cane seem to be able to compile some sketches.
    i tried to use the PTPDevinfo seketch but when ever i try to compile it this is the error im im getting i have no idea how to fix it :

    i’d really appreciate it if you can guide me how to fix it ,
    also one more question am i able to change the EXIF description tag or any other tags using your library for each picture i shot.

    thank you

    By adding the line using namespace QP; to psconsole.h the errors reduce to only three:

    Despite my efforts I am unable to resolve those errors. I am using Arduino IDE version 1.5.2, QP version 1.5.x for arduino 1.5.x and USB Host Shield 2.0.

    Sorry about the long error list. Any help would be greatly appreciated.

    Thank you,

    Joshua

    • Looks like the issue with QP. Can you compile and run QP examples?

      • Joshua

        I can compile two of the three QP examples. The one that I can’t compile is dpp_qk.ino. I get the following errors when trying to compile that one:

        bsp.cpp: In function ‘void __vector_7()’:

        bsp.cpp: At global scope:

        Am I missing a file?

        Hi,

        I also have this problem, after looking up various AVR threads on PROGMEM, and trying Arduino versions 1.0, 1.0.1, 1.0.5, 1.5 & 1.5.6-r2 (under Mac OS X) I still have the exact same errors as posted.

        The use of “const” or alternate compiler versions have been said to address this problem, but I have not luck….

        Could someone please point me in the right direction.

        ERRORS:
        Arduino: 1.5.5 (Mac OS X), Board: “Arduino Leonardo”

    Good day, Oleg! Will this PTP library work on Arduino Leonardo by it self?.. Is there a easy way to debug / check / develop for PTP on PC? I wont to extend the library with support for Sony cameras. Thanks!

  • Alejandro Caballero

    I am trying to control a Nikon CoolPix P520 with an Arduino Mega ADK. Is there any documentation available to learn how to do this?

    Thank you.

  • pcace

    Hi,

    i do have a Problem with compiling the PTPDevInfo. I do not know what to do:
    i use the Arduino IDE 1.0.5 with MacOsx 10.9.2.

    Any Idea what to do?

    Hmm,

    its so sad, that there seems to be no more help with this library, it was exactly what i really needed.. but i simply cannot get it to work – it has been almost 2 weeks of trying. i followed the cmplete qp tuts, to get qp working (and i can compile the examples) but still loooots of error messages when trying to compile nkremote or even PTPDevinfo…

    Maybe someone can just tell me if its somehow possible to get this to work with whatever arduino version at all? Maybe someone could upload the working QP Lib + PTP Lib…

    What versions do use?
    I am relly depressed….

    Sorry,

    Pcace

    + There is no qp for arduino 1.0.x anymore, and i cannot find it anywhere. could someone upload it?

      • Pcace

        There is still no qp for arduino 1.0.x anymore.. so i think i will never get this to work properly…
        Or is there anyone who is willing to help me with this?

        Thanks,
        Pcace

        Hi Lauszus,

        I red almost every post and every comment on this site, but I cannot make the PTP 2.0 work with the USB_Shield 2.0.
        I tried different IDE, different QP version, your PTP_20 all-in-one library version, but I still get a lot of error even in the simplest PTPDevInfo sketch, most of the errors are “*** causes a section type conflict”.

        So, besides continue to tell to use your link, there is any suggestion you can give us in order to make this work?

  • Harpix

    Hi everybody,
    I’m stuck, same condition experienced by MatteGarry:

    “I tried different IDE, different QP version, your PTP_20 all-in-one library version, but I still get a lot of error even in the simplest PTPDevInfo sketch, most of the errors are “*** causes a section type conflict”.”

    anyway to properly compile PTP_20?

    Thank you

  • Simon

    Dear Oleg & dear all,

    the project sounds very nice. I tried to compile the PTP_2.0 for NKremote about days and days with different setups but there still errors.
    My actual sw setup is:

    Arduino IDE 0022
    USB Host Shield 2.0 Library
    PTP_2.0 Library (i tried the setup made by Lauszus as well)
    QP_Arduino 1.0.x (QP/C++ 4.5.03/QM 3.1.1)

    I would like to try the QP_Arduino 4.3.00 but there is NO source anymore.
    Could anybody share a zip-file for windows with me?!

    My actual error set follows:

    In file included from NKRemote.cpp:6:
    C:\Program Files (x86)\arduino-0022\libraries\PTP_20/qp_port.h:3132: error: section attribute not allowed for ‘file’
    In file included from NKRemote.cpp:12:
    /psconsole.h: In constructor ‘PSConsole::PSConsole()’:
    psconsole.h:40: error: invalid cast from type ‘QState (*)(PSConsole*, const QEvent*)’ to type ‘QState (QHsm::*)(const QEvent*)’
    NKRemote.cpp: At global scope:
    NKRemote:10: error: section attribute not allowed for ‘file’
    NKRemote:62: error: section attribute not allowed for ‘file’

    Hope for some replies!
    Thanks a lot!

    I seem to have found a fix for the frequent “… causes a section type conflict” problem with the PTPDevInfo example. Tested with Arduino IDE 1.0.5 on OSX 10.9 and Arduino 1.5.7 Beta on Windows.

    in devinfoparser.h:
    lines 237-244, eight lines beginning with “static const char* ” … change to “static const char* const”. So for example,
    static const char* ptpopNames[];
    becomes
    static const char* const ptpopNames[];

    in devinfoparser.cpp:
    starting in line 3, find the matching eight “const char* ” and change them to “const char* const”.
    For example,
    const char* DevInfoParser::ptpopNames[] PROGMEM = { …
    becomes
    const char* const DevInfoParser::ptpopNames[] PROGMEM = { …

    For me, this made the multitude of other errors disappear, even the seemingly unconnected “__c causes a section type conflict” errors caused by PSTR() calls.
