setting CAN FD baud rate c driver

[mikeatbosch]

The manual and example for stream out with the session set properies is not working, How do you set the FD baud rate?

[GPIB_Guru]

You need to have your database cluster set to be FD with BRS  (if not using a database, you can use the in-memory database ":can_fd_brs:". Then, you just need to set the FD baud rate with a normal set property call (nxPropSession_IntfCanFdBaudRate)

[mikeatbosch]

where ae the "memory" or "can_fd_brs" databases?

[GPIB_Guru]

They don't really exist. They are just constants that you can use if you don't have a real database. The driver essentially creates an empty database in memory with enough settings preconfigured so that your application can work.

:memory: is an empty CAN database. The cluster, by default, would be configured in normal CAN mode. The baud rate is unuset.

:can_fd_brs: is a database with a CAN cluster configured in FD_BRS mode to allow full FD transmission. The baud rate and fd baud rates are unset.

thanks

Still getting an invalid data rate, but it's not an error.

I used the psuedo database for fd and used the enum for FD also, but still invalid rate.

I tried 2 and 8 megbits?

Sorry, its actually no baud rate set HEX BFF63073

[GPIB_Guru]

Did you set both the normal baud rate (i.e., 500000) AND the fd baud rate (i.e., 2000000)?

[mikeatbosch]

I just set the FD baud rate with the SetProperties, I guess you mean to set them both. I'll try that.

[mikeatbosch]

It gets better.

I configured both as you suggested, but when I run I get waring HEX 0x3FF63040-Baud rate supplied exceeds the capabilities of the transceiver. Its warns there may be bus errors-there are.

I thought this card, PCI-8512 was FD capable?
