Detailed Description

Initialization and Configuration functions.

 ===============================================================================
                      Initialization and Configuration functions
 ===============================================================================  
  This section provides functions allowing to 
   - Initialize the CAN peripherals : Prescaler, operating mode, the maximum number 
     of time quanta to perform resynchronization, the number of time quanta in
     Bit Segment 1 and 2 and many other modes. 
     Refer to  @ref CAN_InitTypeDef  for more details.
   - Configures the CAN reception filter.                                      
   - Select the start bank filter for slave CAN.
   - Enables or disables the Debug Freeze mode for CAN
   - Enables or disables the CAN Time Trigger Operation communication mode

Function Documentation

void CAN_DBGFreeze	(	CAN_TypeDef *	CANx,
		FunctionalState	NewState
	)

Enables or disables the DBG Freeze for CAN.

Parameters

CANx,:	where x can be 1 or 2 to to select the CAN peripheral.
NewState,:	new state of the CAN peripheral. This parameter can be: ENABLE (CAN reception/transmission is frozen during debug. Reception FIFOs can still be accessed/controlled normally) or DISABLE (CAN is working during debug).

Return values

None

void CAN_DeInit

(

CAN_TypeDef *

CANx

)

Deinitializes the CAN peripheral registers to their default reset values.

Parameters

CANx,:

where x can be 1 or 2 to select the CAN peripheral.

Return values

None.

void CAN_FilterInit

(

CAN_FilterInitTypeDef *

CAN_FilterInitStruct

)

Configures the CAN reception filter according to the specified parameters in the CAN_FilterInitStruct.

Parameters

CAN_FilterInitStruct,:

pointer to a CAN_FilterInitTypeDef structure that contains the configuration information.

Return values

None

uint8_t CAN_Init	(	CAN_TypeDef *	CANx,
		CAN_InitTypeDef *	CAN_InitStruct
	)

Initializes the CAN peripheral according to the specified parameters in the CAN_InitStruct.

Parameters

CANx,:	where x can be 1 or 2 to select the CAN peripheral.
CAN_InitStruct,:	pointer to a CAN_InitTypeDef structure that contains the configuration information for the CAN peripheral.

Return values

Constant

indicates initialization succeed which will be CAN_InitStatus_Failed or CAN_InitStatus_Success.

void CAN_SlaveStartBank

(

uint8_t

CAN_BankNumber

)

Select the start bank filter for slave CAN.

Parameters

CAN_BankNumber,:

Select the start slave bank filter from 1..27.

Return values

None

void CAN_StructInit

(

CAN_InitTypeDef *

CAN_InitStruct

)

Fills each CAN_InitStruct member with its default value.

Parameters

CAN_InitStruct,:

pointer to a CAN_InitTypeDef structure which ill be initialized.

Return values

None

void CAN_TTComModeCmd	(	CAN_TypeDef *	CANx,
		FunctionalState	NewState
	)

Enables or disables the CAN Time TriggerOperation communication mode.

Note

DLC must be programmed as 8 in order Time Stamp (2 bytes) to be sent over the CAN bus.

Parameters

CANx,:	where x can be 1 or 2 to to select the CAN peripheral.
NewState,:	Mode new state. This parameter can be: ENABLE or DISABLE. When enabled, Time stamp (TIME[15:0]) value is sent in the last two data bytes of the 8-byte message: TIME[7:0] in data byte 6 and TIME[15:8] in data byte 7.

Return values

None
