|
* @brief CMSIS STM32L4xx Device Peripheral Access Layer Header File. |
|
* |
|
* The file is the unique include file that the application programmer |
|
* is using in the C source code, usually in main.c. This file contains: |
|
* - Configuration section that allows to select: |
|
* - The STM32L4xx device used in the target application |
|
* - To use or not the peripheral's drivers in application code(i.e. |
|
* code will be based on direct access to peripheral's registers |
|
* rather than drivers API), this option is controlled by |
|
* "#define USE_HAL_DRIVER" |
|
* |
