Function Documentation

uint32_t CRC_CalcCRC16bits ( uint16_t  CRC_Data)

Computes the 16-bit CRC of a given 16-bit data.

Parameters
CRC_Datadata half-word(16-bit) to compute its CRC
Return values
16-bitCRC

Definition at line 256 of file stm32f30x_crc.c.

uint32_t CRC_CalcCRC8bits ( uint8_t  CRC_Data)

Computes the 8-bit CRC of a given 8-bit data.

Parameters
CRC_Data8-bit data to compute its CRC
Return values
8-bitCRC

Definition at line 268 of file stm32f30x_crc.c.

void CRC_DeInit ( void  )

Deinitializes CRC peripheral registers to their default reset values.

Parameters
None
Return values
None

Definition at line 95 of file stm32f30x_crc.c.

void CRC_PolynomialSizeSelect ( uint32_t  CRC_PolSize)

Selects the polynomial size.

Parameters
CRC_PolSizeSpecifies the polynomial size. This parameter can be:
  • CRC_PolSize_7: 7-bit polynomial for CRC calculation
  • CRC_PolSize_8: 8-bit polynomial for CRC calculation
  • CRC_PolSize_16: 16-bit polynomial for CRC calculation
  • CRC_PolSize_32: 32-bit polynomial for CRC calculation
Return values
None

Definition at line 130 of file stm32f30x_crc.c.

void CRC_ReverseInputDataSelect ( uint32_t  CRC_ReverseInputData)

Selects the reverse operation to be performed on input data.

Parameters
CRC_ReverseInputDataSpecifies the reverse operation on input data. This parameter can be:
  • CRC_ReverseInputData_No: No reverse operation is performed
  • CRC_ReverseInputData_8bits: reverse operation performed on 8 bits
  • CRC_ReverseInputData_16bits: reverse operation performed on 16 bits
  • CRC_ReverseInputData_32bits: reverse operation performed on 32 bits
Return values
None

Definition at line 159 of file stm32f30x_crc.c.

void CRC_ReverseOutputDataCmd ( FunctionalState  NewState)

Enables or disable the reverse operation on output data. The reverse operation on output data is performed on 32-bit.

Parameters
NewStatenew state of the reverse operation on output data. This parameter can be: ENABLE or DISABLE.
Return values
None

Definition at line 185 of file stm32f30x_crc.c.

void CRC_SetInitRegister ( uint32_t  CRC_InitValue)

Initializes the INIT register.

Note
After resetting CRC calculation unit, CRC_InitValue is stored in DR register
Parameters
CRC_InitValueProgrammable initial CRC value
Return values
None

Definition at line 208 of file stm32f30x_crc.c.

void CRC_SetPolynomial ( uint32_t  CRC_Pol)

Initializes the polynomail coefficients.

Parameters
CRC_PolPolynomial to be used for CRC calculation.
Return values
None

Definition at line 218 of file stm32f30x_crc.c.
