| 5 | * @brief CMSIS STM32L1xx Device Peripheral Access Layer Header File. |
||
| 6 | * |
||
| 7 | * The file is the unique include file that the application programmer |
||
| 8 | * is using in the C source code, usually in main.c. This file contains: |
||
| 9 | * - Configuration section that allows to select: |
||
| 10 | * - The STM32L1xx device used in the target application |
||
| 11 | * - To use or not the peripheral's drivers in application code(i.e. |
||
| 12 | * code will be based on direct access to peripheral's registers |
||
| 13 | * rather than drivers API), this option is controlled by |
||
| 14 | * "#define USE_HAL_DRIVER" |
||
| 15 | * |
