Python in Linux environment on RPI

K_Research -- Please note that you are responding to a three+ year old thread,and doubtful OP will see, hasn't logged in since last January.

Well aware of the dates of this topic I added the info to help others in the future working on GPS projects, I found this thread doing a Google search for from gps import *

I am Python stupid and I am searching for code that will allow users to create a GPS Waypoint by pushing a button. I found Python code records a track to a .CSV file and that works well now I just need to create Waypoints.

I am running out of luck I suppose I should create a topic and post my current code and ask for suggestions?

Thanks

yes, post the code. that and what you are expecting or wanting it to do. i don't know anything about GPS or Waypoints. maybe i will learn from your response.

I have a Raspberry Pi GPS project I am working on, the goal is to record GPS Tracks and to create Waypoints with the push of a button, so far I have the recording Tracks working, no luck on creating Waypoints.

I saved the below Python code to a folder on my Desktop/GPS I navigate to that folder in Terminal by typing cd Desktop/GPS hit enter then type python3 savetrack.py hit enter again.

If your getting a GPS signal you will see your location data start streaming at the same time if you open file manager and navigate to /home/pi/Desktop/GPS you will see a file named something like 20200904-000000_GSPData.csv basically its the date and time the file was created followed by GSPData.csv (look at line 9 of the code you can edit the filename) Use CTRL + Z in Terminal to stop recording the GPS data.

To finish this project I need to start and stop recording Tracks and Waypoints by pushing buttons, either with Touch Screen or by mechanical buttons.

Note: all the ### is my edits or entries, I included a link to the author of the code.

Suggestions, comments, questions? Thanks in advance.

The code.
