No errors and no warnings are returned in segger. I use the same approach in MPLAB X IDE for PIC32 and values are updated with no problem..

Since this is a .h file you are defining a unique instance of these variables for every time the header file is included. As they are "static" each of these instances is not visible to any other module, but each is visible withiin that c file which included the .h file; remove "static" and you will see a flood of errors about multiple definitions. So to use them as global variables place them in a single c or cpp file and delete the "static" prefix; also keep the variables in the .h file, but replace "static" with "extern" which tells each c file that these variables are indeed global.

I'm no absolute expert in C, but I've worked with it for years already and I've never seen something like this. Does it even compile? Do you have warnings?

You should declare your variables in the header file and define them in the source file. You can't have them static and want them to be public at the same time. Also declaring everything as volatile is bad practice.

I'd advise you to read some C basics. There are tons of threads in stack overflow where you can start. For example: stackoverflow.com/.../variable-declaration-in-a-header-file
