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. 
         (+) Configure the CAN reception filter.                                      
         (+) Select the start bank filter for slave CAN.
         (+) Enable or disable the Debug Freeze mode for CAN.
         (+) Enable or disable 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 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

Definition at line 468 of file stm32f30x_can.c.

void CAN_DeInit ( CAN_TypeDef *  CANx )

Deinitializes the CAN peripheral registers to their default reset values.

Parameters:
CANx,:where x can be 1 to select the CAN1 peripheral.
Return values:
None.

Definition at line 152 of file stm32f30x_can.c.

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

Definition at line 309 of file stm32f30x_can.c.

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 to select the CAN1 peripheral.
CAN_InitStruct,:pointer to a CAN_InitTypeDef structure that contains the configuration information for the CAN peripheral.
Return values:
Constantindicates initialization succeed which will be CAN_InitStatus_Failed or CAN_InitStatus_Success.

Definition at line 172 of file stm32f30x_can.c.

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

Definition at line 443 of file stm32f30x_can.c.

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

Definition at line 400 of file stm32f30x_can.c.

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 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

Definition at line 497 of file stm32f30x_can.c.
