Atollic TrueSTUDIO - STM32 and Lora

[panoss]

I 've built a Lora sender with Arduino.
I want to rebuilt it with STM32 (STM32F030F4P6).

So I 'm thinking of starting with the Lora library.
I mean to convert it to Atollic studio code (a class I suppose).

(I 've also found an STM32 STM32duino library that might help)

Am I on the right track for accomplishing my goal?

How do I create a class in TrueSTUDIO?
I just create a new file in src folder of my project?
Right click on Src folder->New->Class?

Thank you but it 's for the STM32 with the Arduino IDE.
Anyway, I 've managed to blink an LED with TrueSTUDIO.
But I have no clue how to go further...
Any help is welcome.

I 've seen the examples in TrueSTUDIO (File->New->Download new example project) but didn't help me much.
I still don't know how to create a library (or whatever is the right term in TrueSTUDIO).
I can't find any tutorial. The tutorials I find are about using the IDE or they are wit STM32duino.
