QGC source code explained

#1

Hi everyone.
I am trying t go deep inside the source code of QGC, so i can later build my own application based on some features of the software that i will be choosing based on my needs.
I would like to ask you where can i find i full guide going through the code, in a way that it makes the code clear to me when reading it.
And if there is any advice you could give me, it will be much appreciated.
Thank you.

Hi everyone,

Does someone know how RTK streaming is implemented in QGroundControl? I could not find any reference to that in the development guide.

I was wondering if there was fixed base station implemented or if it is possible to add that in QGroundControl. This will help me attain the fixed RTK lock soon even if I have to restart QGroundControl.

Well after months of reading the code, i couldn’t find a method that could simplify the code, all i did is read the code and try to follow along the developer guide (it can help you to know where to start from) and do some debugging when i want to know a specific piece of code how it works…
Generally what helps is to focus on a specific topic and follow along the code related to it , and as i said try reading the developer guide it gives helpful tips on how the coding is made…
I encourage you to try first making a simple app to send/receive mavlink messages , and then go for bigger topics.
I hope this will be of any help to you.
