ofxMetaMotion

MetaMotion addon for OpenFrameworks, automatically searches for MetaMotion device via BLE device name MetaWear, connects to the device and streams the Euler orientation angles from the MetaMotion device.

Setup

MacOS

  • Add CoreBluetooth.framework to the project's target Frameworks within the xcodeproj
  • Add the following Run Script to your Build Phases
rsync -aved "$OF_PATH/addons/ofxMetaMotion/libs/libmetawear/lib/osx/libmetawear.dylib" "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/Frameworks/";
install_name_tool -id @executable_path/../Frameworks/libmetawear.dylib "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/Frameworks/libmetawear.dylib";
install_name_tool -change libmetawear.dylib @executable_path/../Frameworks/libmetawear.dylib "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/MacOS/$PRODUCT_NAME";

Quick example:

ofApp.h

    metamotionController mmc;

ofApp.cpp 

    // in ofApp::setup()
    mmc.setup();
    
    // in ofApp::update()
    mmc.update(); // update handles device searching and auto-connection
    mmc.getAngle();
