CAN interfacing to TI DSPs

[chibesa]

HI,

I am new to using CAN. I am trying to interface the national instruments
PCI-CAN2 (high-speed CAN) to the texas instruments TMS320LF2407 CAN module.
I am currently simply trying to establish communication between the two CAN
modules. I am using some of the C application examples provided by NI in
developer studio 5.0. The software for the DSP is written in assembly language
in code composer. How can I possibly make the two CAN modules communicate???.

Thank you.

Your question is intriguing. The setup isn't extremely difficult - I was
able to make the two communicate with each other within a few days. It's
just trial and error, learning about how the registers in the DSP work, and
using the interact.vi that came with the can card.

if you aren't familiar with the programming of the DSP module then it's
going to be much more difficult.

Dear Caleb,

Thank you for your rapid response regards the mentioned subject. I have some
experience of programming the LF2407. Can you please give me more pointers
as to how you actually achieved this communication. What settings on both
the DSP and the PCI-CAN2 card did you make?. How did you test that they were
communicating as required?.

What literature sources would you recommend for me to get to develop this
communication quickly??.

Thankyou very much for your help.

Chibesa.
