1.3.3.25 CANx_TxEventFifoCallbackRegister Function

C

void CANx_TxEventFifoCallbackRegister(CAN_TX_EVENT_FIFO_CALLBACK callback, uintptr_t contextHandle) // x - Instance of the CAN peripheral

Summary

Sets the pointer to the function (and it's contextHandle) to be called when the given CAN's Tx transfer events occur.

Precondition

CANx_Initialize must have been called for the associated CAN instance.

Parameters


Param	Description
callback	A pointer to callback function which function prototype definedby the CAN_TX_EVENT_FIFO_CALLBACK data type.
contextHandle	A value passed into the callback function as callback parameter.

Returns

None.

Example

void APP_CAN_TxEventFifoCallback(uint8_t numberOfTxEvent, uintptr_t contextHandle)
{
}
void APP_CAN_TxFifoCallback(uintptr_t context)
{
}
uint8_t loop_count = 0;
uint8_t txFiFo[CAN0_TX_FIFO_BUFFER_SIZE];
CAN_TX_BUFFER *txBuffer = (CAN_TX_BUFFER *)txFiFo;
memset(txFiFo, 0x00, CAN0_TX_FIFO_BUFFER_ELEMENT_SIZE);
txBuffer->id = 0x100000A5;
txBuffer->dlc = 8;
txBuffer->xtd = 1;
txBuffer->fdf = 1;
txBuffer->brs = 1;
for (loop_count = 0; loop_count < 8; loop_count++){
    txBuffer->data[loop_count] = loop_count;
}
CAN0_TxEventFifoCallbackRegister( APP_CAN_TxEventFifoCallback, NULL);
CAN0_TxFifoCallbackRegister( APP_CAN_TxFifoCallback, NULL);
// Transmit message from Tx FIFO
CAN0_MessageTransmitFifo(1, txBuffer);

Remarks

None.
