Ada_Drivers_Library/arch/ARM/STM32

These projects represent general MCU devices, such as a platform based on an STM32F405.

Use one of these project if that is the kind of hardware your target is based upon. For example, the Crazyflie 2.0 uses an STM32F405, so project stm32f40x.gpr would be appropriate.

Note that if you are using one of the *_Discovery boards, there are projects available in the boards directory at the root of this repository. The corresponding project would be appropriate since it includes the additional hardware specific to the board. With that approach the additional hardware specific to that board will available, such as the user buttons and LEDs.
