- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- (+) Enable CRC AHB clock using __HAL_RCC_CRC_CLK_ENABLE();
- (+) Initialize CRC calculator
- (++) specify generating polynomial (peripheral default or non-default one)
- (++) specify initialization value (peripheral default or non-default one)
- (++) specify input data format
- (++) specify input or output data inversion mode if any
- (+) Use HAL_CRC_Accumulate() function to compute the CRC value of the
- input data buffer starting with the previously computed CRC as
- initialization value
- (+) Use HAL_CRC_Calculate() function to compute the CRC value of the
- input data buffer starting with the defined initialization value
- (default or non-default) to initiate CRC calculation
