How to add CAN bus on LaunchXL-F28069M InstaSPIN Lab 11?

Daddio

Hello,

I am using TI's LaunchXL-F28069M eval board, I am running the TI DRV8305 PMSM InstaSPIN Lab11, and I am following the Simulation and Code Generation of TI InstaSpin Using DRV8305 Tutorial. On the eval board, CAN bus is exposed on J12. How do I add CAN bus to the .psimsch and configure the CAN so that I can control the motor externally from a separate controller?

Thank you,

Hi,

Yes, we can use the CAN bus to send and receive messages in PSIM. In the examples (file→open examples) there will be a code generation folder then there will be CAN bus example for each target. The path will be something like: \examples\Code Generation\F2803x Target\CAN bus

The example is meant to be run on two CPUs connected via the CAN bus, there is test_CAN_bus_1 and test_CAN_bus_2.

You'll notice that the message ID for the outgoing messages from bus1 matches the incoming ID in the bus2 and vice versa.

You can also use USB based tools like the CANUSB to send messages from you computer, you'll need to make some jumper wires to use it.

This tutorial is available through help→ tutorials→ code generation and gives a detailed overview of how to set things up. Tutorial - implementing CAN bus communication in PSIM
