Parsing Human Interface Device (HID) data

    Dec 03 2017 | 5:59 pm
    Hi, What is the best way of parsing HID data? I want to use the "hi" object and get data from moving my SpaceNavigator HID device. I have tried this with the hi-object help patch and I get a lot of data when moving the 3D joystick, but how do I easily parse this and map it in a convenient way? What I would like is something like a multislider object where each slider represent one data stream for one joystick axis such as up, down, turn and so on from my 3D joystick. I also get some very large values as output from the hi-object. Values such as: 4294959498 (10 digits). What is the resolution of an axis on a HID device? How do I find information about the maximum and minimum values? I guess I need some knowledge of this to scale the sliders appropriately?

      No point in reinventing the wheel I always say: You can thank Tarik.

      Thanks a lot! That is why I love this forum, there is always someone quicker and smarter than me who have solved a lot of the problems already! And he got the numbers nicely aligned from 0 to 1 with 0.5 in center when the Space Navigator is not touched, just great stuff!

      Check out how he is using it to navigate through a 3D audio visual landscape, incredible stuff: I assume its the same Tarik anyway...

      Wow! That was way more complicated than the application I had in mind... I just wanted to use it to send CV voltage to my Eurorack...

      I find its best not to compare yourself to Tarik!
