Module-prefix CANS

generic conversion module header of Can signals from CAN buffered reception to DATA Manager and vice versa

Function Documentation

CANS_AddMessage()

STD_RETURN_TYPE_e CANS_AddMessage	(	CAN_NodeTypeDef_e	canNode,
		uint32_t	msgID,
		uint8_t *	ptrMsgData,
		uint32_t	msgLength,
		uint32_t	RTR
	)

Add message to transmit buffer, message will be transmitted shortly after.

Parameters

canNode	canNode on which the message shall be transmitted
msgID	ID of the message that will be transmitted
ptrMsgData	pointer to a uint8_t array that contains the message that will be transmitted
msgLength	length of the message that will be transmitted This parameter can be a value of CAN_identifier_type.
RTR	Specifies the type of frame for the message that will be transmitted. This parameter can be a value of CAN_remote_transmission_request

Return values

E_OK	if successful, E_NOT_OK if buffer is full or error occurred

Here is the call graph for this function:

CANS_Enable_Periodic()

void CANS_Enable_Periodic

(

uint8_t

command

)

enable/disable the periodic transmit/receive.

Returns

none

CANS_Init()

void CANS_Init

(

void

)

initializes local variables and module internals needed to use conversion of can signals. Until now no initialization is needed and thus the function does nothing.

CANS_IsCurrentSensorCCPresent()

uint8_t CANS_IsCurrentSensorCCPresent

(

void

)

set flag for sending of C-C by current sensor.

Returns

retval TRUE if C-C is being sent, FALSE otherwise

CANS_IsCurrentSensorPresent()

uint8_t CANS_IsCurrentSensorPresent

(

void

)

set flag for presence of current sensor.

Returns

retval TRUE if a current sensor is present, FALSE otherwise

CANS_MainFunction()

void CANS_MainFunction

(

void

)

handles the conversion of can signals from and to datamanager database or other modules defined by the getter and setter configuration.

Here is the call graph for this function:

CANS_TransmitBuffer()

STD_RETURN_TYPE_e CANS_TransmitBuffer

(

CAN_NodeTypeDef_e

canNode

)

Transmits canNode transmit buffer.

Parameters

canNode

canNode on which the message shall be transmitted

Return values

E_OK	if transmission successful, otherwise E_NOT_OK

Here is the call graph for this function:

CANS_TransmitMessage()

STD_RETURN_TYPE_e CANS_TransmitMessage	(	CAN_NodeTypeDef_e	canNode,
		uint32_t	msgID,
		uint8_t *	ptrMsgData,
		uint32_t	msgLength,
		uint32_t	RTR
	)

Transmits message directly on the CAN bus.

Parameters

canNode	canNode on which the message shall be transmitted
msgID	ID of the message that will be transmitted
ptrMsgData	pointer to the data that shall be transmitted
msgLength	Specifies the data length
RTR	Specifies the type of frame for the message that will be transmitted.

Return values

E_OK	if transmission successful, otherwise E_NOT_OK
