Problem to convert from STM32F4

[Lopinhos]

Hello Ishachar.
I'm having trouble converting the program to the STM32F4.
I'm still very inexperienced in programming, even more so something created and complex.
I was wondering if you could give me a hand with this question!
In the image there are the initial errors that appear to me, but after defining the pins other errors appear, and after that error it goes back to the lines in red
