- * @file stm32f4xx_hal_crc.c
- * @author MCD Application Team
- * @version V1.1.0
- * @date 19-June-2014
- * @brief CRC HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Cyclic Redundancy Check (CRC) peripheral:
- * + Initialization and de-initialization functions
- * + Peripheral Control functions
- * + Peripheral State functions
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The CRC HAL driver can be used as follows:
-
- (#) Enable CRC AHB clock using __CRC_CLK_ENABLE();
-
- (#) Use HAL_CRC_Accumulate() function to compute the CRC value of
- a 32-bit data buffer using combination of the previous CRC value
- and the new one.
-
- (#) Use HAL_CRC_Calculate() function to compute the CRC Value of
- a new 32-bit data buffer. This function resets the CRC computation
- unit before starting the computation to avoid getting wrong CRC values.
