  • Aviation Module

    Hello

    4D Systems produced a system for aviation, as you can see in this video:
    https://www.youtube.com/watch?v=behrtWFxszg

    Unfortunately no one on 4D systems could help me for starting a kind of similar project like this for data logging for aviation purposes. I would have loved to start to rebuild this project and then, due to the learned experiences, start my own GPS and IMU logger project. But I also know that the customer service might be tired of all these newbie questions.

    It even starts with the simple question: Which processor is suitable for my kind of use: Diabolo 16 (like they used in the Video) or a PICASO processor or even a gen4-IoD (does this include a processor?)?

    Does anyone know about some sort of this project?

    Thanks for any help

    Hello kai,

    Welcome to the forum.

    We are not at all 'tired of all these newbie questions' we are happy to help.

    The project in the video was based around a MPU9250, BMP280 and a Ublox GPS module connected to an atmel processor and the data read from there via SPI on the Diablo screen. The image data for that instrument is very large many GB. It works very well. The MPU9250 together with the RTIMULIB library is about the best combination we tried and doesn't seem to suffer from gyro drift. Acceleration shows up a little in the attitude indicator but that depends on how much damping there is in the code.

    If you are considering a similar project a Diablo16 processor will give you the best results, We have recently tried connecting all the sensors to a IoD-09 http://www.4dsystems.com.au/product/IoD-09 which acts like a server for motion and position and displays a compass. A Diablo display with a MOTG-WiFi Module http://www.4dsystems.com.au/product/motg/ then connects to the server and collects it via UDP and displays the instruments very smoothly, the gen4-IoD does the task of displaying the instruments quite well too. It is still a work in progress but should be finished soon.

    The gen4-IoD uses the ESP8266 as it's processor for managing WiFi and for displaying graphics but it does this very well. The Diablo & Picaso processors are faster due to their dedicated graphics.

    I hope this helps

    Best regards

      Hello Paul

      do you use this kind of thing for getting the IMU-data: https://www.amazon.com/MPU-9250-BMP2.../dp/B01NCC6RCQ
      (This is just an amazon link to explain what I need more and if we are talking about the same issue)
      I need another AD-converter or another digital pressure sensor connected to this datalogger. At least I am engineer and would love to read more about your projects to adapt it to my needs. Then I would like to use your modules to built my own one.
      Just in case you want to test it (within airplanes) feel free to ask me :-) it would be my pleasure

      Anyway I am interested in this kind of built. Do you share this????

      Thanks

      Kai

        Hello Kai,

        Yes, I have used one of those and they work very well and are not that expensive. The MPU9250 is about the best sensor I have come across
        Thank you for your kind offer of testing, I will keep that in mind
        There are just a few little things to finish off with our device with but I will keep you posted and will gladly help you with your project.

        Best regards

        Paul

          Hello Paul

          How do you use the IoD-09 exactly - for data acquisition and collecting the GPS and IMU data or/and for data logging and visualising?
          Do you publish this (or the old project shown in the video mentioned above)? if yes .... where?

          When do you think you have finished the project for showing the community (and me :-) )?

          Kind regards

          Kai

            Hi Kai,

            The IoD-09 is collecting data from the IMU and GPS and has a visual compass, It is then sending out the data via WiFi UDP to anything that connects to it. Logging can also be done at the same time.

            It isn't published at the moment but I will let you know as soon as it is and when it is finished.

            Many thanks

            Paul

              This project looks very interesting. I have just ordered a 4d display for use in an engine monitoring system for an experimental aircraft. I would also like to look at the possibility of displaying basic visual flight instruments on the screen. I would need an airspeed indicator, compass, and altimeter display - is there a plan to release the code/images for the guages used in the aviation project in the earlier post? This would be a great help as the guages in visi genie are not suitable for this application.

              Thanks

                Hello Rich

                that is something I also wanted to include - anyway to include a speed indicator (differential pressure) is something I am most afraid of.

                There are some pressure sensors with:

                analogue output
                http://www.ebay.de/itm/Airspeed-Sens...38.m2548.l4275
                With MPX7002DP sensor

                or pressure sensors with digitial output:
                https://pixhawk.org/peripherals/sensors/px4airspeed
                http://store.jdrones.com/digital_air...irmag03kit.htm
                https://hobbyking.com/en_us/pixhawk-...___store=en_us
                (Manual: https://hobbyking.com/media/file/1/3/130697_manual.pdf)
                With 4525DO sensor
                (Manual: http://www.te.com/commerce/DocumentD...ocLang=English)

                These sensors are used for the pixhapwk flightcontroller. Therefore I do not know if they use a specified protocol or standard SPI. But this would be a perfect match for your needs, Rich.
                Maybe Paul can help me to include this in the mentioned project????? :-)
                I can not predict, which one is better. But this is one of my hurdles for realizing this project.

                @Paul: are you able to tell me a date, when this project you mentioned,might be published (this year)?

                Thanks

                Kai

                  Thanks Kai,

                  I actually already have the differential pressure sensor you linked, I just haven't yet got round to connecting it to an Arduino or similar. If I can get the guages the way I need them I will look to progress this aspect of my project.

                  Cheers

                  Rich

                    Hello,

                    I should be able to make this available in a few day's just a couple of things to finish off,

                    I hope this helps

                    Best regards

                      @Paul: That would be really nice. I really would love to test this in real.
                      - Which one of the sensors would be easier to install in your code (the digital would be more precise, I guess)

                      @Rich:
                      - Which one do you mean (or better: which one do you already own) - the analogue version or the digital version?

                        Hello Kai,

                        I have the MPXV5010DP differential pressure sensor, which is analogue. I have not yet experimented with it. There is plenty of source code available online, especially in the Arduino forums, so I am hoping to be able to make this aspect work fairly painlessly.

                        Paul,

                        Thank you, that sounds great. I have just got my new display up and running and look forward to trying out these guages when they are available.

                        Many thanks
                        Rich

                          Hello Rich

                          Thanks for sharing. I am quiet curious about this 4D Systems version. I just searched for your sensor and found this interesting link, which already has all my topics included in "one box".
                          http://experimentalavionics.com/efis-19264-ver-1-2/

                          But the Diabolo processors are seem to be better and I just ordered on StarterKit. If it does not fit my needs, it sure is a pretty little thing to develop something or just to get experience.

                          Kai

                              Hello Kai.

                              It won't be much longer. I will contact you as soon as it is available. Thank you for your patience
