User needs to select:

  • map type which has to be the same one used in MissionPlanner image
  • source folder will be automatically set to MissionPlanner download folder
  • destination folder which can be the root of the SD card (if mounted) or a temp folder to be eventually copied to the SD card later, please read the notes below!

Note: please double check your map tiles path:

  • for Horus Widget version 2.0.0 or later use /IMAGES/yaapu/maps

Note: The resize tool will resize all tiles found in MissionPlanner offline cache, if there are tiles that should not be resized and transfered to the SD card it is necessary to clear the download folder C:\ProgramData\Mission Planner\gmapcache\TileDBv3\en* before starting the map prefetch tool.

Configuration

Once the tiles are copied to the SD card it is necessary to run the Widget Config Tool and enable Google Maps support image

Zoom controls requires selecting a channel as "emulated wheel channel", moving a switch or a slider up/mid/down will control zoom.

Please make sure you have a valid GPS sensor in OpenTX telemetry page, if not please do a sensor discovery!
