Incompatibility with other libraries

[SunboX]

First, thanks for this great library! :)

Many libraries nowadays are using the STM32Duino core instead of the Maple core. Regarding this thread [1], the Maple core seems also to be outdated and difficult to set up.

Is there any plan to move the Library to STM32Duino core?

ah, just found this issue: https://github.com/stm32duino/Arduino_Core_STM32/issues/668 (followup: https://github.com/stm32duino/Arduino_Core_STM32/issues/687)

It would be a difficult task and I am not up to it.

I am not sure what you mean by saying the Maple core is difficult to set up. It seems to be pretty straightforward: download it to your Arduino/Hardware directory, fix permissions of scripts if necessary, and it works, at least for me.

Additionally, the Maple core involves less abstraction and hence should produce smaller and faster code (though to be honest, I haven't checked it).

The big advantage of the standard core is that it supports more devices, however.

My setup for f103c8 clone in platformio. So to setup start with:

[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
framework = arduino
board_build.core = maple
