Wow, your edit on the last reply made me think about something I was doing a few days ago. I was trying to activate SIMPLEFOC_STM32_DEBUG, which is done by defining that, but adding “#define SIMPLEFOC_STM32_DEBUG” on the main code didn’t work, but uncommenting that line inside the library did the trick. Well, it is the same thing here, it only worked when I changed that inside the library, on the file hardware_api.h, not adding it on the first line of the main arduino code.
It freaking runs now. THANK YOU!
