|
|
* @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"
|
|
*
