UCANS32K1SIC: S32K146 CAN Rx FIFO Examples

[Shubha_Ravi]

Hello Team,

Iam trying to receive CAN frames using RX FIFO instead of buffer method. I looked through your website and couldn't find any useful information on the same and I tried few configurations to implement Rx FIFO and couldn't succeed. It would be really helpful if you could provide me with some example codes and configuration using Rx FIFO for S32K146 controller.

Hello Team,

Thanks for the input, I tried to execute your demo code and it worked.

I need to introduce the logic for cycle time so i have used the following logic, but instead of 50ms Iam getting 5sec, what needs to be corrected to get the values in ms. I assumed 1 tick is 1msec but Iam getting 1tick =100ms so Iam unable to get a proper logic for cycle time. Could you please let me know what could be the problem?

void Init(void)

{

ComObjCAN.systick = OSIF_GetMilliseconds();

}

void main()

{

 value = OSIF_GetMilliseconds();
if ((value-ComObjCAN.systick) == 50) {
ComObjCAN.systick = value;
 ComCAN_Transmit();
 }
