SPC570S-DISP CAN Frame Error

SKim.19 · ‎2020-12-20

I'm currently trying to transmit the CAN frames using SPC570S-DISP.

I applied it to the SPC570S-DISP using only the example source code.

However, the CAN TX signal is output as shown in the picture above.

Upper the picture is the peripheral Register set value.

FLT_CONF is setting Bus off status and to be generating the Tx_Error_Counter.

I think the Can Test Application source code seems to have a problem.

If anyone has solved this issue, please help.

Hello ,

SPC570S CAN demo configures the CAN in loopback mode. So, there is n output.

In order to enable output, loopback configuration flag has not to be checked. See attached pictures.

Hello,

do not forget to configure also the external pins:

and close JP6 and JP8

See page 4/9 in schematics [link]

Hello,

Thank you for interesting in my issue.

Giuseppe and Erwan said the external pin and the loopback check box.

I modified. but it's the same result.

if the loopback check box is enabled or the external pin is not set then the signal is not generated.

I don't know the reason for what is a strange signal.

Would you check the CAN Example using the STC570S50 chip in SPC570S-DISP Board?

Help me, please.

Thank you.
