Example for airframe file

Add to your firmware section: This example contains all possible configuration options, not all of them are mandatory!

<module name="cv_detect_contour">
  b'<define name="DETECT_CONTOUR_CAMERA" value="front_camera|bottom_camera" />\n    '
  b'<define name="DETECT_CONTOUR_FPS" value="0" />\n  '
</module>

Define Options

• name: DETECT_CONTOUR_CAMERA value: front_camera|bottom_camera
  Description: Video device to use
• name: DETECT_CONTOUR_FPS value: 0
  Description: The (maximum) frequency to run the calculations at. If zero, it will max out at the camera frame rate
