Function Documentation

void CAN_DBGFreeze ( CAN_TypeDef CANx,
FunctionalState  NewState 
)

Enables or disables the DBG Freeze for CAN.

Parameters
CANxwhere x can be 1 or 2 to to select the CAN peripheral.
NewStatenew 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 493 of file stm32f4xx_can.c.

void CAN_DeInit ( CAN_TypeDef CANx)

Deinitializes the CAN peripheral registers to their default reset values.

Parameters
CANxwhere x can be 1 or 2 to select the CAN peripheral.
Return values
None.
Parameters
CANxwhere x can be 1 to select the CAN1 peripheral.
Return values
None.

Definition at line 167 of file stm32f4xx_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_FilterInitStructpointer to a CAN_FilterInitTypeDef structure that contains the configuration information.
Return values
None

Definition at line 334 of file stm32f4xx_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
CANxwhere x can be 1 or 2 to select the CAN peripheral.
CAN_InitStructpointer 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.
Parameters
CANxwhere x can be 1 to select the CAN1 peripheral.
CAN_InitStructpointer 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 197 of file stm32f4xx_can.c.

void CAN_SlaveStartBank ( uint8_t  CAN_BankNumber)

Select the start bank filter for slave CAN.

Parameters
CAN_BankNumberSelect the start slave bank filter from 1..27.
Return values
None

Definition at line 468 of file stm32f4xx_can.c.

void CAN_StructInit ( CAN_InitTypeDef CAN_InitStruct)

Fills each CAN_InitStruct member with its default value.

Parameters
CAN_InitStructpointer to a CAN_InitTypeDef structure which ill be initialized.
Return values
None

Definition at line 425 of file stm32f4xx_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
CANxwhere x can be 1 or 2 to to select the CAN peripheral.
NewStateMode 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 523 of file stm32f4xx_can.c.
