+> If you want to use debug printing (enabled using the macro `STA_DEBUGGING_ENABLED`) in a TACOS project, you should also enable float formatting under `Project Settings -> C/C++ Build -> MPU/MCU Settings -> Use float with printf from newlib-nano`. This allows you to format print floats using `STA_DEBUG_PRINTF`. If this setting is not enabled, your software will crash when debug printing floats.

+The configuration file shown in the example above initializes the project assuming that you are working on a STM32 Nucleo of type F407. Typically, you are using a different microcontroller, however. In this case you can replace the line
 ```cpp
+#include <sta/devices/stm32/mcu/STM32F407xx.hpp>
+```
+with the include
+```cpp
+#include <sta/devices/stm32/mcu/STM32_YOUR_MCU_HERE.hpp>
+```
+So far, only a few chips are officially supported. For not officially supported chips use this as the include:
+```cpp
+#define STA_STM32_SWD_USART_IDX <IDX OF YOUR UART>
+
 #include <sta/devices/stm32/mcu/common.hpp>
 #define STA_MCU_LITTLE_ENDIAN
 #define STA_PLATFORM_STM32
 ```
+> [!NOTE]  
+> The definition of `STA_STM32_SWD_USART_IDX` allows you to specify which UART handle to use for debug printing. If undefined, a default handle for Nucleos will be used. You can also add the macro `STA_STM32_ASEAG` instead if you are a cool kid using ASEAG-based hardware.
