APRS Map display - Marinus

While reading about Marinus ( http://hamradioprojects.com/authors/wa5znu/+marinus/) , an APRS map display .. I notice I hv all of the parts - a DigiX ( https://www.kickstarter.com/projects/di … ard-with-w ), a 2.2" 320x240 TFT SPI display, SD card slot on the DigiX, MicroAPRS libs , Taner's version of packet decoding port of ArgentData Shield for MicroAPRS modem..

Even though all the hardware are better/bigger/faster, the codes still runs fine, thanks to Arduino ...

I generated the bmp map tiles at http://hamradioprojects.com/authors/wa5 … rinus/osm/ using aprs.fi Info page ( Location:    3°nn.xx' N 101°nn.yy' E - locator OJnnTEyyAK - show map - static map ) ... and loaded it into a SD card on the DigiX .. ( but the bmp resolution was wrong... )

Hook up the MicroAPRS Serial to Serial3 on DigiX ( DigiX have 3 hw serial port ) the codes was decoding the packets from the MicroAPRS modem...

Some of the pictures of corrected resolution bmp from the author, Leigh...

We can further joint develop this into a more advance APRS mapping solution for Arduino ...

The OSM python script to download/convert all the maps into bmp format..

On Debian, install libjpeg-dev and python PIL modules to get the script working :-

sudo apt-get install libjpeg-dev
sudo pip install PIL

command line :- python tile.py XXXXyy 14

XXXXyy comes from aprs.fi Maidenhead locator codes under Info page...

Re: APRS Map display - Marinus

Wow! This is pretty advanced! Is the map display scrollable or does it show a fixed area?

Re: APRS Map display - Marinus

The maps are not scrollable ( not yet written, I guess ) ... probably can move from tiles to tiles using a directional buttons... or zoom-in or out on different map zoom tiles.

All the codes are available and fully working ( with minor modification to the MicroAPRS.h by Taner .. )

I managed to generate 7x7 lcd/bmp tiles maps from a 11x11 OSM tiles ...

Since the DigiX / DUE  hv like 96Kb of ram on board, I was thinking of using of storing all the Rx stations and plotting them within the same map tiles...
