Next step is to add gps position

the bis is simple , like this
osm_gps_map_set_center_and_zoom(map, 53.865802833333335,  -1.6721983333333331,12)

for othe INCLUDE's
the gps converter will need
libnmea from github
HERE
if link blocker on
copy this
https://github.com/jacketizer/libnmea

Tile Bits Already have
for the reads
managed to get BaCon Serial Working + WiFi using BaCon Method

OPEN URL$ & ":" & PORT$ FOR NETWORK AS mynet

Also Looking at a hackaday on the lib osm files to add seamap png's : hence not tested

Hello Alex


some feedback for the RPI3
as you know I don't have a boat
but I feel comfortable testing gtk3 code demos from the shoreline
the RPI3 needs some very small adaptations in the PRAGMA area
*unless you edited the osm-gps-map.h

these worked on the RPI3
thanks
Joe

Hi Joe

Thanks for the feedback ,
the lib source code has an example, at first was curious as to the why include the header
in short
your bits did the trick

PRAGMA INCLUDE <gtk-3.0/gtk/gtk.h>
PRAGMA INCLUDE <osmgpsmap-1.0/osm-gps-map.h>

I will update the demo and remove the header + add local link to docs

BR
Alex

Hi Joe & All
had some terrible casting problems re gobject etc etc

so in short these are the bits that work, plus now have the gps working with serial & wifi
also got the track/rout plotting in

PRAGMA INCLUDE <gdk/gdkkeysyms.h>

now looking to clean up the code ready for posting
Q&A

Q does it require the GPS
A NO
it is select by choice if only want the maps

Thanks Alex,

Your code works for me as well, I get a window with a nice map

I have used OpenStreetMaps a lot in the past and it is cool how easy it can be embedded in GTK.

But I do see some GTK/GDK warnings and errors in the background. Though this is probably not your code, would there be a way to get of these warnings?

E.g.:

<....>

Hi Peter

possible most warnings are the Missing tile or tiles, I think says he

IE there missing from the cache , all tiles are set in cue , that usual settles esp when zoom level is above 5

ADDED . IE the IE , same as OPEN file FOR WRITING

note the demo uses /tmp as the storage , hence every boot will = same results

as mentioned , works is still on going

fso rom last post , now concluding the code to download the openseamaps/seamarks.

now in last steps of coding 'compositing the two png's into one png' this proved to be a teaser

then options will be tmp or cache dir home/user

ADDED

(osm:23817): GdkPixbuf-CRITICAL **: 19:00:52.820: gdk_pixbuf_new_from_data: assertion 'width > 0' failed

OK that is the bit that proved to be a teaser . that width 0 = empty png , generally size of 334

the bit for down loading the seamarks , HERE WE NEED TO GET THE HEADER FIRST
SPLIT the header then check the bits 334 of png =0 , I think says he

IF INSTR(b$,"334") THEN
 PRINT array$[4]
ELSE

The ELSE = download

beyond that I use BaCon FILELEN as a double check

Alex

the test bit as of just a few hours ago

as an example to the above

Hi All

OpenStreetMap 2 seamap converter added See post #1

BR
Ales

[alexfish]

Hi All

asp can see from recent post RE OPEN FOR DIRECTORY ,
the seamap converter function has been re-written , Code at first post

this part has is now part of the general gui hence one can use the app and then convert to seamap on the go
by clicking on the button , added tracking enable / disable , here one can scan an area and then convert to seamap at will, see picky

vessel tracking now enabled as in, IE it leaves a trail.

+ have now added means of weather and tides , using a bit of PicScale internally on some older images
,
final update hopeful next week , as can see there are two panes, when i mention final update
this means it will be down to the user to add what ever to the left hand pane

BR
Alex

Hi All

still behind after finding another bug , now resolved

new interface option added RE webkit and openseamap

options will be tide and weather
or
tide and weather

have searched high & low for AIS decoder based on c
how ever if install gps lib then can use that option, this one should give ais info , not tested as yet
Joe has baconised the bits
read here
sourceforge.net/p/bacon-qt5/wiki/gps_from_localhost/
have tested python ais , a bit of code + typical reply

import ais
#message = NMEAMessage(b"!AIVDM,1,1,,B,15M67FC000G?ufbE`FepT@3n00Sa,0*5C")

Hi All

found another problem

normally I do not use the GPSD , this was installed and resulted serial read device problems

1. device busy or permission denied :: obvious the gpsd is still running
2. normally the gpsd does not run unless you tell it IE gpsd /dev/tty* . * = your device

3. found that after fresh boot or reboot serial read or even cat the device = errors , garbage

How does one stop the gpsd + get the device back to normal ?

So after a while in days finally found a way around the problem using one of the gpsd tools gpsctl

man gpsctl
find command -r

in short and in may case this worked
-r /dev/ttyACM0
but use at your own risk

to check example and result

gpsctl  /dev/ttyACM0
/dev/ttyACM0 identified as a NMEA0183

although this device is a 'u-blox GPS' may have on your system
ubxtool
man ubxtool

the Why, can read here HERE
