Problem with compile code for STM32F401

[brightproject]

I have problem with compile code for STM32F401 on MCUFRIEND_kbv library then use Arduino_Core_STM32.
With core from rojercrark no problem.
What could be the problem?

Hi @brightproject,
I've tried to compile for blackpill F4 and met issue with WR_PIN not defined.
Looking for that in the library, it seems you have to add STM32F4 support need to be added to the library.
Mainly in the mcu_special*.h as it is done for other STM32.
Unfortunately, I will not be able to help on that, you should open an new issue to the library to get help.
