Flick Large gesture control

  • R

    Hello all,

    I have tried to use the flick Large sensor together with my Raspberry Pi 2 to control the interface of the MagicMirror, as I have made some pages and wanted to scroll through them.

    What I have managed to do is to control MMM-pages, MMM-page-indicator and the default news module via my MMM-flick module.

    The controls are as follows:

    Swipe Left - Decrement Page
    Swipe Right - Increment Page
    Swipe Up - Show news description
    Swipe Up again - Open News page
    Swipe Up as the news page is opened - Scroll down the news page
    Swipe Down - Close News Page
    Swipe Down again - Close News Description

    I`m currently working on implementing the touch functionality. I want to also have mouse control.

    The code is not perfect, I`m working it.

    Here is the code (note that I have changed some libraries for it to work with the ASUS Tinker Board, as far as I know I`m the only one who has working flicklibs on the TinkerBoard. If someone is interested in getting the flick sensor to work with the TinkerBoard pm me ):

    Nvm, I got it working perfectly! xD

    Hello, is it possible to place it behind the mirror? Could you show us a picture of your integration into MagicMirror?
    Thank you in advance.

    That is exactly what I’m planning to do. In theory it works behind the mirror, but you will lose the touch gestures more than likely. Unfortunately I do not have the mirror yet (it has not been delivered yet), but I’ll post a picture/results when I get it.

    So far I wrote the code this way:

    Left/right swipes go through MMM-pages & MMM-pages_indicator

    Up/down swipes open/close newsfeed details

    Each gesture also triggers the LED on the sensor board.

    I’m still thinking what other things I can do with the remaining gestures.

    I’ll update the correct code after I clean it up a bit.

    @radu_stancu Thank you for your answer I look forward to your feedback, because I would also like to use this solution. 🙂

    Could you describe, if you were successfull with the implementation of the board? Best Regards.

    @steffenschmidt, I was successful to some extent. I have managed to use the gestures from the board to control the interface. Up, down, left and right are working and more will follow when I know what I want them to do. The only problem is that the flick sensor is NOT WORKING behind the mirror, probably because of the aluminum/silver layer that makes a mirror a mirror.

    I will work on the project in the winter holidays and post some more details.

    Updated the code, and also support for the Asus Tinker Board.

    This is exactly what Im looking for. Im trying to get your module to run but Im first of all not a programmer (can do simple things in python an such)

    I altered your python script to work with my skywriter board, easy enough. But i wonder how i set up the config file? Just load the module? If I do that I get a error that says "cannot find module “python-shell”

    I was hoping the sensor would work behind the mirror to but it wont. I will put it on the inside of the frame insted…
