Arduino-based controller for Canon EOS cameras

Arduino Camera Controller

Arduino Camera Controller

Today, I’m writing about two more pieces of digital camera control firmware that have being posted to PTP gihHub repository. Alex Gluschenko, the author of PTP library for Arduino, developed two sketches, one called EOSRemote and the other EOSCamController to demonstrate PTP library capabilities. The code allows requesting camera settings, such as shutter speed, aperture, ISO, etc., change them, as well as take shots. It supports Canon EOS cameras and was tested on EOS 400D, 450D, and 7D; other cameras with similar command set ( see my collection of PTP device info dumps ) may work as well.

This is how the code works: when connection is established, camera sends back an initial packet with all its current settings along with a list of all possible values for each setting. Possible values depend on a camera model as well as lens that are mounted. For example, some cameras may have exposure compensation range from -2 to +2, others from -5 to +5; some lens have max.aperture 1.4, others – 3.5, an so on. The list of values received from the camera is placed in built-in EEPROM of Arduino microcontroller. After that, values are used in setting (called “property” in PTP lingo) change commands sent to the camera. When camera mode, such as Av, Tv, or lens is changed, camera sends initial packet again. The Arduino code tracks changes and updates the list stored in EEPROM.

Hardware requirements for both controllers are pretty standard. The EOSRemote sketch uses Arduino serial port facility for I/O, and the only hardware necessary is Arduino Duemilanove, Uno, or compatible clone, as well as USB Host Shield. User interface is designed with simple terminal emulator program in mind. It can be used with a PC connected to Arduino directly or over some distance utilizing a pair of serial to RF converters, such as ever-popular Xbee. The following screenshot shows top-level menu with camera connected and recognized.

The second controller has been designed for field operations. It uses HD44780-compatible character LCD display, rotary encoder with push switch, and one extra button. Here is controller’s schematic. Title picture shows the implementation and picture on the right shows main components. The controller uses 3.3V Arduino Pro from Sparkfun, “Minimal” variant of USB Host Shield and 3.3V LCD display. LCD, encoder and switch are mounted on a small prototype PCB which plugs directly into USB Host Shield’s GPIO pins.

In addition to setting/displaying shooting parameters and taking shots this controller works as intervalometer with extended bracketing. If desired, a self-timer can be set up before the first shot in series. Also, each shot can be bracketed as wide and granular as camera exposure compensation range and step allows. For example, on 7D it is possible to set bracketing from -5 to +5 with 1/3 step between shots – more than enough for good HDR.

Let’s talk about the code. To compile the sketches, current versions of Arduino_Camera_Control and USB Host Shield libraries are necessary. Additionally, Time library from Arduino Playground has to be installed. Also, the code uses Quantum Leaps QP framework – a compact and robust open source implementation of UML state machines. Miro Samek is currently working on Arduino port of QP framework; in the mean time, I’ll show how to make Arduino-compatible setup from source code. Only QEP component of the framework is used and installation is simple.

First, create a directory under arduino-00xx/libraries/, call it. let’s say, ‘qep’. Then download the QP/C++ from SourceForge. Unzip the archive somewhere else, navigate the directory tree to qcpp_x.xx/qep/source and copy all files to Arduino library directory. After that, go to qcpp_x.xx/include directory and copy qassert_.h, qep.h, qevent.h and qs_dummy.h header files to the same Arduino library directory. Now, download AVR port, unzip it, navigate to ports/avr/qk/gnu and copy qep_port.h to Arduino library directory. Finally, in Arduino library directory, open qassert.h in text editor and insert line #define Q_NASSERT before the line containing #ifdef Q_NASSERT (line 47 as of ver.4.1.01 of QDKCPP-AVR-GNU). Save the file. The sketches should now compile – try it with your camera and let me know if you have any problems.

Finally, I want to talk about hardware variants. Camera controllers described here can be built using “standard” Arduino (Duemilanove or Uno) plus “Simple” USB Host shield. This setup is easy to work with and troubleshoot. However, it is not as easy to power such setup – usually you would need 4xAA batteries, which is somewhat bulky. On the other hand, 3.3V setup can be powered from a single LiPo so 3.3V Arduino Pro/”Minimal” USB Host Shield setup is preferable for a portable controller. It is also possible to build a controller with 3.3V Arduino Pro Mini/USB Host Mini – the tiny form factor makes building more difficult but the resulting controller is going to be much smaller and also quite a bit cheaper. The code is compatible with any of hardware variants described above.

I’m planning to continue camera control code development – next milestone is Canon Powershot command set support, and it is very close to release. I’m also planning on making a small controller for Canon DSLR video mode. Stay tuned!

Oleg.

  • Great job!
    Can arduino write down raw’s to SD card via ethernet shield ? It can be awesome mobile solution for timelapses )

  • Dmitry

    Hello Oleg!

    I still can’t stop to thank you for this little helpful shield.

    have you tried to set AEB in manual mode? if yes – could you please share the code sample?

    thanks, Dmitry.

    • Exposure compensation doesn’t work in manual mode.

      • Dmitry

        but that could be? I am absolutely sure that I can set it in manual mode in the camera menu – AEB/Exposure compensation?
        it that some hardware limitations?

        • Dmitry

          found!
          here is a code sample:

          #define EOS_DPC_AEB 0xD1D9

          ...

          Eos.SetProperty(EOS_DPC_BracketMode, 1);
          delay(200);

          Eos.SetProperty(EOS_DPC_AEB, 0x18);
          delay(200);

          the available values for EOS_DPC_AEB are the positive shift values from the exposure compensation values list. I’ve found it in the canon sdk document.
          for example – 0×18 is equal to +3, 0×10 to +2 and so on.

          however, my 7D(1.2.2) sometimes don’t allow me to set AEB in manual mode. I can’t find the reason, but if I swith to another mode (Av,Tv,P) and then set AEB then is appears in M mode. that looks like a bug in a firmware, but I don’t know how to reproduce in in 100% cases.

          • This is how I interpret this: the exposure compensation setting affects exposure meter in the camera. The exposure meter is visible in the viewfinder ( a scale at the bottom ). In one of the auto modes exposure meter also sets exposure of the shot. in manual mode exposure meter is disconnected – you can still see it but if won’t set the exposure of the shot.

            To summarize: if you can’t see the exposure meter scale (as is often the case of remote camera control via PTP) setting Ev in manual mode makes no sense.

      • Jan van Bodegraven

        Exposure compensation and exposure bracketing are two different things.

        Bracketing will work in Manual, normally through varying exposure time.

        • Bracketing is supported in the library, the property name is EOS_DPC_BracketMode. The camera will take 3 shots. Ev method, used in this controller, is more flexible – you set margins (like +/- 6) and step (like 1/3), and controller sets each Ev value and takes a shot.

    Hi

    This sound pretty cool!
    I am looking for a way to read the filename of tge lasten taken picture
    Is this possible with this program?
    Or is there an example with it?

    THANKS!

    • In PTP, files are called objects. The object is accessed by its ‘handle’. There are examples of getting list of handles an getting object info. Since files are big and can’t be buffered in Arduino memory, getting the object itself is application-specific. You start by using GetObject(), then write a parser which will be called on receiving each USB packet from the camera.

  • rogier

    Nope exactly the same errors like i have with 1.0….

    • rogier

      It is running now, the problem was that i did not install the usb library

      So now up to find out what Oleg means by
      “In PTP, files are called objects. The object is accessed by its ‘handle’. There are examples of getting list of handles an getting object info. Since files are big and can’t be buffered in Arduino memory, getting the object itself is application-specific.

      I am totaly no programmer…. so lets go google and we will see ;-)

    I want to move focus box up\down\left\right,what functionS should do that?
    what functions should do screen zoom 1X\5X\10X?

    THANKS!

  • Dmitriy

    Hello, Oleg!
    Unfortunately I can’t get to work any Arduino Camera Control sketch. A bunch of errors appears when I trying to compile the code. I found solution here: USB Host Shield library needed, but I already dowloaded and extracted it into library directory from github (as described above). It doesn’t change anything. Hope for your help.

    I’m trying to connect eos 50d using arduino nano and usb host shield nano.

  • Rob

    I’m using arduino 1.0.3 and have tried everything to get this to compile. I can compile EOS bulb, ESO capture, eos dual capture, eos eventlab, eosfocus, and yams_ptp20 but I can not compile EOScameracontroller, EOChdrcapture or EOSremote. I have tried installing the usb1 and camera controls with no luck. I also tried usb2 and ptp2. I have tried many different revisions of the qep downloads. Here is the errors I get from EOScamera controller.

    Any help would be great.

  • Rob

    Here is an update for my progress. I think I’m getting close.

    I’m using a windows XP Service Pack 3 Dell Laptop.

    1. I downloaded Arduino 0022 IDE from http://arduino.cc/en/main/software and then installed it.

    2. I then downloaded USB_Host_Shield_2.0-master from https://github.com/felis/USB_Host_Shield_2.0

    3. I then downloaded PTP_2.0-master from https://github.com/felis/PTP_2.0

    4. For the above two files in step 2 and 3 I clicked on the zip button on the page and downloaded the full zip file.

    5. I then unziped the two files to the \arduino-0022\libraries directory

    6. I renamed USB_Host_Shield_2.0-master directory to USBHost

    7. I renamed PTP_2.0-master to PTP

    8. Steps 6 and 7 were needed because the Arduino IDE did not like their names.

    9. I downloaded the time.zip file from http://playground.arduino.cc/Code/Time I had to click on The download to get the file.

    10. I unzipped time.zip to the \arduino-0022\libraries directory. This created the following 3 directories:

    DS1307RTC
    Time
    TimeAlarms

    11. I then downloaded the file qpcpp_4.1.05.exe from http://sourceforge.net/projects/qpc/files/QP_C%2B%2B/4.1.05/ directory.

    12. I installed this to c:\qep directory.

    13. I make a new directory \arduino-0022\libraries\qep

    14. I copied all the files from C:\qep\qep\source to \arduino-0022\libraries\qep

    15. I copied the following 4 files from C:\qep\include to \arduino-0022\libraries\qep

    qassert.h
    qep.h
    qevent.h
    qs_dummy.h

    16. I downloaded qdkcpp_avr-gnu_4.1.01.zip from http://www.circuitsathome.com/camera-control/arduino-based-controller-for-canon-eos-cameras by clicking the blue words download AVR port

    17. I unzipped the file to c:\avr

    18. I copied the file qep_port.h from C:\avr\ports\avr\qk\gnu to \arduino-0022\libraries\qep

    19. I then opened qassert.h from the \arduino-0022\libraries\qep directory and added the line #define Q_NASSERT just before #ifdef Q_NASSERT

    20. I started the Arduino IDE opened the PTP EOSCamController

    I got the same errors again

    This is the same errors when I used the Arduino 1.0.3 and 1.0.2 IDE’s

    All my errors have been with no Arduino hardware connected to the computer.

    I’m really excited about using the with my Canon 450D camera. I have the USB board coming in the mail on 1/16/2013. I have just got the XRF usb transmitter and receiver.

    All my errors have been with no Arduino hardware connected to the computer.

    I then tried to use the usb1 and camera control files

    21. I deleted the directory C:\all\downloads\arduino\arduino-0022\libraries\USBHost and C:\all\downloads\arduino\arduino-0022\libraries\PTP

    22. I downloaded the file Arduino_Camera_Control-master.zip from https://github.com/felis/Arduino_Camera_Control

    23. I downloaded the file USB_Host_Shield-master.zip from https://github.com/felis/USB_Host_Shield

    24. I unzipped them both to the \arduino-0022\libraries directory

    25. I renamed them so that Arduino would like them

    This time all would compile except for the following:

    EOSCapture

    EOSCapture.cpp:14:24: error: MemoryFree.h: No such file or directory

  • Rob

    I got EOSCapture to compile by removing the line #include

    I’m not sure if that will affect the operation when I try to use it.

  • Rob

    I did it. They all compile now. I got the PTPDeviceInfo and PSDevProp files to compile by renaming the arduino-0022\libraries \Arduino_Camera_Control directory to arduino-0022\libraries \ptp.

  • Rob

    Here are the 20 steps I took to get all the camera files to compile. I hope this helps others.

    I’m using a windows XP Service Pack 3 Dell Laptop.

    1. I downloaded Arduino 0022 IDE from http://arduino.cc/en/main/software and then installed it.

    2. I downloaded the file USB_Host_Shield-master.zip from https://github.com/felis/USB_Host_Shield

    3. I then downloaded PTP_2.0-master from I downloaded the file Arduino_Camera_Control-master.zip from https://github.com/felis/Arduino_Camera_Control

    4. For the above two files in step 2 and 3 I clicked on the zip button on the page and downloaded the full zip file.

    5. I then unziped the two files to the \arduino-0022\libraries directory

    6. I renamed USB_Host_Shield-master directory to USBHost

    7. I renamed arduino_camera_Control-master to ptp

    8. Steps 6 and 7 were needed because the Arduino IDE did not like their names and ptp is used in some of the sketches.

    9. I downloaded the time.zip file from http://playground.arduino.cc/Code/Time I had to click on The download to get the file.

    10. I unzipped time.zip to the \arduino-0022\libraries directory. This created the following 3 directories:

    DS1307RTC
    Time
    TimeAlarms

    11. I then downloaded the file qpcpp_4.1.05.exe from http://sourceforge.net/projects/qpc/files/QP_C%2B%2B/4.1.05/ directory.

    12. I installed this to c:\qep directory.

    13. I make a new directory \arduino-0022\libraries\qep

    14. I copied all the files from C:\qep\qep\source to \arduino-0022\libraries\qep

    15. I copied the following 4 files from C:\qep\include to \arduino-0022\libraries\qep

    qassert.h
    qep.h
    qevent.h
    qs_dummy.h

    16. I downloaded qdkcpp_avr-gnu_4.1.01.zip from http://www.circuitsathome.com/camera-control/arduino-based-controller-for-canon-eos-cameras by clicking the blue words download AVR port

    17. I unzipped the file to c:\avr

    18. I copied the file qep_port.h from C:\avr\ports\avr\qk\gnu to \arduino-0022\libraries\qep

    19. I then opened qassert.h from the \arduino-0022\libraries\qep directory and added the line #define Q_NASSERT just before #ifdef Q_NASSERT

    All compile except for EOSCapture

    20. I got EOSCapture to compile by removing the line #include

    I’m not sure if that will affect the operation when I try to use it.

    • John

      Thanks Rob for sharing this solution. It did work for me. After a bit of poking around I did find a solution to make this work with the Arduino 1.0.5 IDE.

      The main thing that I found is that WProgram.h has been updated to Arduino.h. I had to make changes to:
      - canoneos.h
      - ptpcallback.h
      - simpletimer.h
      - scheduler.h

      After addressing those, I was getting an error about BYTE not being defined in the scope for the ptp.cpp. A quick google search, relieved that Serial.print may have also changed. I modified line 107 of the ptp.cpp file. It is now, Serial.print(c,HEX); instead of Serial.print(c,BYTE);

      Oleg,

      I wanted to thank you for your work with this, I am very great full and love the USB host shield. Thanks again, and I hope that the above will help further development.

  • Rob

    I got the usb shield today soldered the pins on and connected the camera 450D loaded EOSRemote and it works great. Thank you so much! Great code. Now I have to try to understand it a little more. Thanks Again Oleg

  • Rob

    I made a small visual basic app the used you ptp rev 1 CanonEOSRemote example code. Here is a link to a screen shot and the VB app. I added the extra files the need to be in the same directory to get it to run. It need lots of work. I have the source for VB 4.0

    http:\\sirenxoom.no-ip.org:8080\canoneos.html

  • Axel

    Does anyone know how to get information from the lens: (1) Focal length – if the lens is zoomed to 35mm, 65 mm, etc and (2) what the focus distance of the lens is – 6″, 3’4″, etc.

    All help would be greatly appreciated. Thanks.

  • Rob

    Hi Oleg, I was wondering if you have time could you please add an additional feature to your EOSRemote sketch for me? I’m using the rev 1 version I could not get the PTP2 or USB_Host2 to compile.

    Right now your main menu looks like this:

    0.
    1. Capture
    2. View Settings
    3. Change Setting

    Could you change it to:

    0.
    1. Capture
    2. Capture & Download Thumbnail
    3. Capture & Download Image
    4. View Settings
    5. Change Setting

    I noticed your post to peter on another page where you have the example code to get the image objects handle and you said that you can use the handle with GetObject() or GetThumb() but I can not seem to make them work.

    If you have time to do this I might also need help receiving the image at the computer. I know you can open a com port for a serial read to a file but I already have the port open so that I can get to the Arduino and your code that is running. I currently using a small visual basic app that opens the com port using MSComm1. I’m using a RichTextBox to display your menu from the EOSRemote.

    (See http://sirenxoom.no-ip.org:8080/canoneos.html for a screen caputre of the VB app)

    I have this working wirelessly with a XRF Xbee clone. So far the range is way better than I thought but I can not see the images until I go to the camera.

    The only other thing I noticed is that if I restart either the Arduino serial monitor or the VB app I only get start on my screen. I have to go out to the camera and turn it off and then back on again to get camera connected on my screen. The communication to the camera does not work unless I cycle the power on the camera. It would be nice if the camera was already connected that the code in the Arduino could notice it.

    What I asking for may not be possible. I do not have anywhere the experience you do with the camera and Arduino.

    I have used Gphoto to do this a few years ago but the Wifi or wireless UBS device range is very short. I gave up on that a few years ago.

    Any help with this would be great.

    Thanks

    Rob

    • How do you download a file via a serial terminal?

      • Rob

        I’m not using a serial terminal. I’m using a Visual basic application to talk to the arduino over the serial com port. Can the camera send the image file via the Arduino to the PC com port as a stream of bytes?

      • Rob

        Hi Oleg, I was thinking that you guys had found a way to transfer pictures from the camera to the computer with the PTP code. I looked at all of the examples but none of them transfer the pictures from the camera. The name Picture Transfer Protocol (PTP) leads you to thing that you could transfer a picture. It has been years since I have used classes in my programming. I have started relearning them. I never had much use for them but you professional programmers use them a lot. They must be really useful. I’m going to have to try writing some simple classes just the get a feel for them again. Sorry if I was asking for too much that can’t be done. I printed out the EOSRemote code and all of the supporting header files. It is over 100 pages in 8 font. This is really a long complicated program.

        Rob

        I use the camera for astro images. Either on a scope or for just wide field star and milkyway images. I can remotely control the mount to reposition the direction the camera/scope is pointed. I live in northeast Ohio and use dew heaters to keep the scope and lens clear from dew or frost. Some of the clearest nights here it is very cold outside. It would be very nice to look at a thumbnail after I reposition the mount just to center the image. After the imager is centered I could take all the long exposures required to complete the image. So a few minute wait to transfer the image would be way better than going out into the dark and cold out to the pier a 5 to 6 hundred feet from my home. My web site has some of the images I’ve taken. Most are for expensive CCD cooled cameras. I an little new to the DSLR imaging but the images should be as good if not better then the ones on my web site. http://sirenxoom.no-ip.org:8080/

        Rob

      • Rob

        I got the EOSRemote to connect to the camera with out having to cycle the cameras power. This is so very hard. Its going to take months to figure out this code. Oleg very good project you have made. Its forcing me to do a lot of oop studding that I should have done when I was younger.

  • Rob

    I’m using a Visual basic app that reads the data from the com port and display it in a text box. If I know I picture is comming I think I can write the code to put the code into a file and then display it in a image control.

  • Rob

    I made the VB app just for your code. It was very easy and the code is very short. Look at the link I have the exe file there too. I only program as a hobby and have very little experence with classes. I mostly use Visual Basic these days.

    After your code is in the Arduino Uno I only run the VB app to see your menu take picture and view and change the camera settings.

    I’m thinking that after the VB app has the image data that I can then put it into a file and add .jpg

    I might have to read up on the format of tha JPG file. My vb app gets all the handle info from the ptpobjectpaser example.

  • Rob

    To get the VB app working you have to enter the com port and the Baud rate then press the connect button.

    there is no error checking so you just have to get it right for it to work.

    The VB app then opens the com port and waits for data from the com port.

    When data is available it displays it in the richtextbox.

    normally I see start with the Arduino connected.

    When I turn on the camera I get camera connected.

    The buttons on the side 0, 1, 2, .. 6 When you press then just send that number to the com port.

    If you press 1 then a 1 is sent to the com port and the arduino makes the camera tak a picture.

    I’m thinking if you modify the code for 2 = caprute and download thumbnail then When I press the 2 button on the VB app I will have the VB app expecting to get an image back from the arduino and modify/save the data as needed to make a real jpg file.

  • Rob

    You could try to receive an image with the VB app as it is written. You should see the data in the textbox. There is be timing issues. The VB app waits for data from the com port if it see some data it grabs it and displays it in the textbox. If a long string of data comes into the com port I think the vb app will display some of it then clear out the textbox and show the next part of it and continue until all the data is read from the com port. The last data displayed right now would be the end of the image data.

  • Axel

    So it’s not possible to get the focus position from the lens but is it possible to get the focal length from a L series zoom lens? ie, the lens zoomed to 33mm? Thanks.

  • Knut

    Hi Oleg,
    first of all thank you for developing. I want to build this camera controller but have a few questions about the bracketing options before i do.

    In a post above you wrote:
    “Bracketing is supported in the library, the property name is EOS_DPC_BracketMode. The camera will take 3 shots. Ev method, used in this controller, is more flexible – you set margins (like +/- 6) and step (like 1/3), and controller sets each Ev value and takes a shot.”

    1. How long is the delay between shots?
    2. Can i change the delay.
    3. What is a “save” value for the delay on my 550D?

  • victor

    Hi Oleg

    By any change do you have the poor sony PTP commands?

    A have a alpha99 it cames with some software really limitated, a asume that the PTP is universal.

    A only need the shutter, focus, aperture and shutter speed….?

    Am intent to build the controler using the arduino

  • Hi Oleg,

    I have been trying to compile this code for a couple of days and I have searched for solutions everywhere, but I still cannot get the EOSCameraControl to compile. I am pretty new to Arduino but I have worked on a few projects, usually I would put the libraries into my ‘libraries’ folder in my sketches folder. However I have read a post that has told me to do the following:

    Use Arduino IDE 0022
    Download PTP_2.0
    USB_Host_Shield_2.0
    Create the QEP folder as per your instructions (from pre 4.3 version) Add the AVR Port H file.
    Add the ‘Time’ Library.

    Place all of the whole folders in the libraries folder, so Arduino_0022\libraries\PTP
    Arduino_0022\libraries\USB_Host_Shield_2
    Arduino_0022\libraries\QEP
    Arduino_0022\libraries\Time

    Then open Arduino_0022 and run the EOS CameraControl by navigating to: File-Examples-PTP-Canon EOS-EOSCamController.

    When I attempt to compile this code I get errors:


    EOSCamController.cpp:16:21: error: qp_port.h: No such file or directory
    In file included from EOSCamController.cpp:25:
    hdrcapture.h:20: error: 'Q_USER_SIG' was not declared in this scope
    hdrcapture.h:34: error: expected class-name before '{' token
    hdrcapture.h:40: error: expected class-name before '{' token

    Please could you point me in the right direction, I am eager to get this working and to see if I can eventually add XBee comms.

    Thanks in advance for any help

  • Hi Oleg,

    Thank you very much for your advice, between that and the forums I have compiled and uploaded EOSCamController.

    My next issue is that I am trying to use an LCD Keypad Shield http://www.linkspritedirect.com/product_info.php?products_id=179

    Any help with getting this to work would be excellent, I know the buttons are all on Analog A0. But I’m not sure where to change the code and also the shield library needs to be added I guess. Or I can just get a standalone LCD if that would be much easier.

    Ultimately I am trying to get the controller working over XBee’s to a remote camera. I would be happy to build a gui in flash for example to control it but I really liked the idea of the remote. I would also like to have video start/stop control.

    I would be happy to pay for some time for you to look at this if you were interested, or if you know of anywhere a similar project is posted.

    Thanks Again, look forward to your thoughts.

  • Hello Again Oleg,

    I’m actually going to say thanks for not getting to the question above (Iknow you are busy) as I have persevered and I am almost there!

    I am having a little difficulty adding the Xbee’s to the EOSRemote, I’ve tried a search on this for help but I am unable to find anything relevant. Are you aware of any such support? I am constantly getting connection issues ‘avrdude: stk500_getsync(): not in sync: resp=0×00′ for example and I think this is down to the XBee shield I am using with the USB Host Shield at the same time.

    As before I would really appreciate your help or advice, a point in the right direction.

    Many thanks

  • Andy

    Hi All,

    I am still having problems getting the EOSRemote to work over Xbee’s. I have configured and tested the Xbee’s I have changed the baud rate to 57600, I have changed the baud rate of the sketch to 57600. But when I add the USB Host shield and xbee shield I am unable to get the serial comms to work.

    I am sure that I need to use SoftwareSerial or a Mega 2560 with extra rx/tx.

    But I am unable to find any information about how to get this working with the EOSRemote.

    Please, please can anyone offer advice on this. The EOSREMOTE is excellent but I really need to get it working wirelessly for my project.

    Many thanks in advance

  • Steve P.

    I was wondering if this has been tested on an 1100D (T3)?
