|
|
- (+) Initialize CRC calculator
|
19

21
|
|
- (++) specify input data format
|
22

- (++) specify input or output data inversion mode if any
|
23
|
|
- (+) Use HAL_CRC_Accumulate() function to compute the CRC value of the

24
|
|
- input data buffer starting with the previously computed CRC as
|
25
|
|
- initialization value
|
26

|
27
|
|
- input data buffer starting with the defined initialization value
|
28
