SD Map Tile File structure

Using Maperitive select your zone and generate your tiles. For that enter to MAP-> Set Geometry bounds draw or expand the square of your zone and run the command generate-tiles minzoom=6 maxzoom=17, It could takes long time, maybe 1 hour or more depending your area.

After that, copy the contents of directory Tiles into your SD in a directory called MAP.

On SD Card map tiles (256x256 PNG Format) should be stored, in these folders structure:

  [ MAP ]
     |________ [ zoom folder (number) ]
                          |__________________ [ tile X folder (number) ]
                                                         |_______________________ tile Y file.png

Firmware install

Please install first PlatformIO open source ecosystem for IoT development compatible with Arduino IDE and its command line tools (Windows, MacOs and Linux). Also, you may need to install git in your system.

For custom ESP32 board run:

pio run --target upload

For ESP32S3 Makerfab board:

pio run -e MAKERF_ESP32S3 --target upload

After the first run, load the icons and assets with:

pio run --target uploadfs

Optional, for map debugging version with specific coordinates, build and install the firmware with the next environment variables, like this:

export ICENAV3_LAT=52.5200
export ICENAV3_LON=13.4049
pio run --target upload

Note: For production version don't forget unset these environment variables.

If the GPS module supports multiple GNSS, uncomment the following flag in the platformio.ini file under the build_flags section

-D MULTI_GNSS=1
