CAN user code fails to load

[unobtainium-42]

When I use #include "../CANJaguar/CANJaguar.h" and try to use the CANJaguar class the code crashes:

Welcome to LabVIEW Real-Time 8.6.1f2

The code compiles with no warnings or errors. I am not using 2CAN, I am using a custom serial connector to the Black jaguar. BDC-COMM works. I updated the firmware and set their board IDs.

It looks like the actual CANJaguar class isn't in your project. You added the cpp files to your project as well as the h files, right?

EDIT: Your problem is you put the CANJaguar code as a separate project. The actual code isn't being built with your user code. If you put a folder reference in your project the the CANJaguar folder it should work, or you could just copy the files directly into your project (that's what we do)

I put the files in the project, and all of a sudden these errors popped up:

Did I forget to include something? More importantly, why didn't this happen before?

[taichichuan]

These are well known errors. You need to include the following line into your CANJaguar.cpp code just above the #include "ChipObject/NiRioStatus.h"

#include "ChipObject/NiRio.h"

This will make the compile errors go away.

HTH,

That worked, thanks.

The robot reports this runtime error via console:

>>>>ERROR: status == -52010 (0xFFFF34D6) in sendMessage() in D:/Eric/Documents/Projects/Robotics/workspace2/Breakaway/CANJaguar.cpp at line 176

And via DS:

<Code>-52010 ERROR: status == -52010 (0xFFFF34D6) in sendMessage() in D:/Eric/Documents/Projects/Robotics/workspace2/Breakaway/CANJaguar.cpp at line 176
NI Platform Services: The requested resource must be initialized before use.

All I do is instantiate CANJaguar objects, like the example. Is there any document I should be reading while doing this? If the error's well known, how was I supposed to find out?

[simpsonboy77]

You need something in your code similar to

CANJaguar* Motor = new CANJaguar(3,CANJaguar::kPercentVoltage);
The 3 is the CANBus id, and the second arguement is a enum for the type of controls. Put this in your initialization. Of course change the name motor to the nameof your variables.

If you have this, post snipets of your code. Also make sure you set CAN IDs to each jaguar. If any 2 share a ID, the bus gets confused. I know you said you set them, but I have had my jaguars reset their IDs for no apparent reason.
