CAN TIME STAMP

JackChen2022 — Wed, 29 Jun 2022 02:31:11 GMT

Hello, I have a question to ask.The S32k148 chip is currently used, and the can communication is configured through the cal_pal component of the S32DS. Now I need to use the TIME STAMP function. I have learned about 53.4.3 Message buffer structure in the manual, but there is no specific usage method. I hope there is a usage routine or example.

Thank you very much for your reply. I use SDK for development here, and register operation is not used. Do you have any other examples?

Hi@JackChen2022

I tried searching the internal system records and there is no such demo code for your reference.

As i said in my first reply, you can read the corresponding registers directly.

Hi @JackChen2022

To get the timestamp of the CAN message , you can read the CS of received CAN message and do AND operation with 0xFFFF , which will give the value of timestamp

timestamp=CS&0x0000FFFF;
