Recently, an infenion xmc1200 came to me, which is sewn in the DAVE4 environment (or the old DAVE3), the first time I encountered this beast, how to write code?

Question

Programming

Before I programmed the AVR in AtmelStudio, and now I need to write the code and flash the infenion xmc1200 in the DAVE4 environment. Wednesday is great. atm, you can use ready-made applications (they are also aps) instead of the usual code, and then flash it. However, their functionality is narrow, I can’t figure out how to write code. I've scoured the internet and found nothing useful. Maybe you know some tutorials, or you just figure it out yourself? Help is needed very urgently.
