static void | CAN_TxInterrupt (canBASE_t *pNode, uint32 messageBox) |
| Called in case of CAN TX interrupt. More...
|
|
static void | CAN_RxInterrupt (canBASE_t *pNode, uint32 messageBox) |
| Called in case of CAN RX interrupt. More...
|
|
static STD_RETURN_TYPE_e | CAN_PeriodicTransmit (void) |
| 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. More...

static void | CAN_CheckCanTiming (void) |
| Checks if the CAN messages come in the specified time window If the (current time stamp) - (previous time stamp) > 96ms and < 104ms, the check is true, false otherwise. The result is reported via flags in the DIAG module. More...
|
|
static void | CAN_SetCurrentSensorPresent (bool command, uint8_t stringNumber) |
| Sets flag to indicate current sensor is present. More...
|
|
static void | CAN_SetCurrentSensorCcPresent (bool command, uint8_t stringNumber) |
| Sets flag to indicate current sensor sends C-C values. More...
|
|
static void | CAN_SetCurrentSensorEcPresent (bool command, uint8_t stringNumber) |
| Sets flag to indicate current sensor sends C-C values. More...
|
|
static void | CAN_InitializeTransceiver (void) |
|
void | CAN_Initialize (void) |
| Enables the CAN transceiver.. This function sets th pins to enable the CAN transceiver. It must be called before using the CAN interface. More...
|
|
STD_RETURN_TYPE_e | CAN_DataSend (canBASE_t *pNode, uint32_t id, uint8 *pData) |
| Sends over CAN the data passed in parameters. This function goes over the messageboxes and marks the ones that should be sent. More...
|
|
void | CAN_MainFunction (void) |
| Calls the functions to drive the CAN interface. Makes the CAN timing checks and sends the periodic messages. More...
|
|
void | CAN_ReadRxBuffer (void) |
| 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. More...
|
|
void | CAN_EnablePeriodic (bool command) |
| enable/disable the periodic transmit/receive. More...
|
|
bool | CAN_IsCurrentSensorPresent (uint8_t stringNumber) |
| set flag for presence of current sensor. More...
|
|
bool | CAN_IsCurrentSensorCcPresent (uint8_t stringNumber) |
| get flag if CC message from current sensor is received. More...
|
|
bool | CAN_IsCurrentSensorEcPresent (uint8_t stringNumber) |
| get flag if EC message from current sensor is received More...
|
|
void UNIT_TEST_WEAK_IMPL | canMessageNotification (canBASE_t *node, uint32 messageBox) |
|
STD_RETURN_TYPE_e | CAN_TransmitBootMessage (void) |
| Transmit startup boot message. More...
