1.29.3.3 CANx_MessageTransmitFifo Function

C

bool CANx_MessageTransmitFifo(uint8_t numberOfMessage, CAN_TX_BUFFER *txBuffer) // x - Instance of the CAN peripheral

Summary

Transmit multiple messages into CAN bus from Tx FIFO.

Description

This routine transmit multiple messages into CAN bus from Tx FIFO.

Precondition

CANx_Initialize has been called.

Parameters

Returns

Boolean "true" when a message has been transmitted.

Example

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;
}
// Transmit message from Tx FIFO
CAN0_MessageTransmitFifo(1, txBuffer);

Remarks

None.
