Hello，
One customer asked the question about TCAN4550:
The interruption is RF0NE and tested it could generate interrupt. And he also tested the CAN sent information. He need to set one interrupt when finished sending or send empty interrupt TCE or TFEE, but his setting has no effect. It is seen via the upper computer that it has received a message from the TCAN, but the TCAN4550 has not generated an interrupt. Why is it?
The position setting interruption
/* Set the interrupts we want to enable for MCAN */
TCAN4x5x_MCAN_Interrupt_Enable mcan_ie = {0}; // Remember to initialize to 0, or you'll get random garbage!
mcan_ie.RF0NE = 1; // RX FIFO 0 new message interrupt enable
mcan_ie.TCE = 1;
//mcan_ie.TFEE = 1;
TCAN4x5x_MCAN_ConfigureInterruptEnable(&mcan_ie); // Enable the appropriate registers
Run the sender several times and the data sent here has been received by the upper computer：
TCAN4x5x_MCAN_TX_Header canheader = Conheader;
canheader.ID = CanID;
。。。。。。。
canheader.DLC = CanDlcCaculate(len);
TCAN4x5x_MCAN_WriteTXBuffer(Index, &canheader, pdata);
TCAN4x5x_MCAN_TransmitBufferContents(Index);
Processing Interrupts at：
if (mcan_ir.RF0N) // If a new message in RX FIFO 0
{
。。。。。。。。 ----------- At this position， it could receive data when upper computer send CAN data
}
if(mcan_ir.TC) //TFE TC TCAN4550 ------------------Here didn't generate interrupt when finished sending data
{
platform_printf("\ntransmit Over \n ");
TCAN4x5x_MCAN_ClearInterrupts(&mcan_ir);
}
Best regards
Kailyn
