7 * @brief CMSIS STM32L4xx Device Peripheral Access Layer Header File.
|
|
|
8 *
|
|
|
9 * The file is the unique include file that the application programmer
|
|
|
10 * is using in the C source code, usually in main.c. This file contains:
|
|
|
11 * - Configuration section that allows to select:
|
|
|
12 * - The STM32L4xx device used in the target application
|
|
|
13 * - To use or not the peripheral’s drivers in application code(i.e.
|
|
|
14 * code will be based on direct access to peripheral’s registers
|
|
|
15 * rather than drivers API), this option is controlled by
|
|
|
16 * "#define USE_HAL_DRIVER"
