Pi-GPS

• Using Tkinter (Python windows system) - GPS6MV2 module

SCREENSHOT

-- python3 gps_tkinter.py

COMMENTS FROM THE CREATOR

• first execute gps_raw.py to test your setup. It will display in terminal latitude/longitude received live from your GPS module.
• if gps_raw.py does not display any value after a 'certain amount of time'... check yoursetup
• execute gps_tkinter.py
• main window + waypoints-list window will open
• it will load the file gps_tkinter.json, which contains the last valid GPS position received (if ever)
• the last valid GPS position is displayed on bottom
• as soon as the GPS module receives a valid position, it will overwrite the gps_tkinter.json value
• I made it this way to write down the last valid position, whatever can occurs after it will be saved in a file not in a volatile memory
• program loop: display last valid position / if new position received, write as the last valid position / display in the program window center the value read - XXX for unreadable and invalid values

FUNCTIONS

• DISPLAY LIVE GPS position
• RECORD history all GPS positions received in a .json file [date,latitude,longitude]
• WAYPOINTS list .json to choose from
• DISPLAY DISTANCE to chosen waypoint
• SET actual GPS position as a waypoint (named by date)
• CLEAR GPS positions history .json

MENU

WAYPOINTS

In this concept Waypoints are collected from the file "gps_tkinter_waypoints.json" This file is easily editable if needed. Version 0-1:

• add actual GPS position as a waypoint in the file "gps_tkinter_waypoints.json" with button "+ POSITION ACTUELLE" top left corner

WAYPOINTS LIST

The list displays waypoints written in "gps_tkinter_waypoints.json" by names. When a waypoint name is selected from the list window, a new window will open, to display name, latitude and longitude. Selecting a waypoint will turn the distance displaying on top right corner of the main program window. The chosen waypoint is written in file "gps_tkinter_waypoint.json".

POSITIONS

Button REC to start recording. The button will turn on Red when activ. A counter displays the count of all GPS positions written in the file "gps_tkinter_datas.json".
