Can someone help me please:)

I have done a project using the code ttn-otaa from the MCCI LoRaWAN LMIC Library. Although it is my first experience with programming a microcontroller. My project worked very well. The problem is that I really can’t make a good flowchart of the raw code sample ttn-otaa. I am willing to pay for it, because this flowchart is really important for my documentation.

I am grateful for every single feedback and idea.

With kind regards
