Function Documentation

CAN_CalculateCounterResetValue()

static uint32_t CAN_CalculateCounterResetValue ( void  )

static

Calculate Reset Value for internal counter in CAN_PeriodicTransmit.

Calculate the least common multiply of message periods in can_TxMessages array. All periods will elapse at this time, so the counter can safely be reset.

Returns

Reset Value for internal counter in CAN_PeriodicTransmit

Definition at line 734 of file can.c.

CAN_CheckCanTiming()

static void CAN_CheckCanTiming ( void  )

static

Checks if the CAN messages come in the specified time window.

The time delta where a message is expected to be received needs to be between the configured limits CAN_TIMING_LOWER_LIMIT_COUNTS and CAN_TIMING_UPPER_LIMIT_COUNTS, If the message is received within the time frame the check is true, false otherwise. The result is then reported via flags in the DIAG module.

CAN_ConfigureRxMailboxesForExtendedIdentifiers()

static void CAN_ConfigureRxMailboxesForExtendedIdentifiers ( void  )

static

Initialize RX mailboxes for usage with extended identifiers.

The first 32 mailboxes are configured via HALCoGen as RX mailboxes to be used with standard 11-bit identifiers. As the configuration if standard or extended identifiers should be used can only be configured for all mailboxes and not individually for each mailbox this configuration is done here.

The HALCoGen configuration for the mailboxes 61-64 is overwritten here and they are configured to received all CAN messages with an extended identifier.

This configuration is only done for CAN nodes canReg1 and canReg2!

CAN_DataSend()

STD_RETURN_TYPE_e CAN_DataSend	(	CAN_NODE_s *	pNode,
		uint32_t	id,
		CAN_IDENTIFIER_TYPE_e	idType,
		uint8 *	pData
	)

Sends over CAN the data passed in parameters. This function goes over the message boxes and marks the ones that should be sent.

Parameters

[in,out]	pNode	CAN interface to use
	id	ID of message to send
	idType	standard or extended identifier
[out]	pData	data to send (8 bytes)

Returns

STD_OK if a message box was free to send, STD_NOT_OK otherwise

Parse all TX message boxes until we find a free one, then use it to send the CAN message. In the HAL, message box numbers start from 1, not 0.

Definition at line 923 of file can.c.

Here is the call graph for this function:

CAN_PeriodicTransmit()

static STD_RETURN_TYPE_e CAN_PeriodicTransmit ( void  )

static

Handles the processing of messages that are meant to be transmitted.

This function looks for the repetition times and the repetition phase of messages that are intended to be sent periodically. If a comparison with an internal counter (i.e., the counter how often this function has been called) states that a transmit is pending, the message is composed by call of CANS_ComposeMessage and transferred to the buffer of the CAN module. If a callback function is declared in configuration, this callback is called after successful transmission.

Returns

STD_OK if a CAN transfer was made, STD_NOT_OK otherwise

Definition at line 682 of file can.c.

Here is the call graph for this function:

CAN_ReadRxBuffer()

void CAN_ReadRxBuffer

(

Checks the data received per CAN. A receive buffer is used because CAN frames are received in an interrupt routine. The TMS570LC4357 does not allow nested interrupts, so interrupts are deactivated during receive. Calls to the database do not work when interrupts are disabled. Receive callbacks are made within this function: as it is not called during an interrupt routine, calls to the database can be made.
