Hi, Are there any working examples yet?

There should be a working demo in the example folder with the library. This example loops CAN1 back to CAN2.

Gene,

I finally got around to trying the Can Bus library, however the example will not compile, giving multiple errors related to "FALSE and TRUE" statments in the main example, PDE, errors related to BOOL statements in the canbus.h file, calls to p32xxxx.h not able to find this file, ect ect.

It appears to throw 10's of errors preventing compiling.

I am using the newst MPIDE 2011-08-22, and the librarys from the Digilent Website.

Do you have an updated Canbus library that works on your PC that you can share or is there something else I need to do to get this working. I am fairly new to programming so having a working example is essential to my being able to adapt the code to my project.

Thanks in advance.

For anyone trying to use the CAN library and getting tons of compile errors. Make sure that you have the correct board selected. If you try building this library with an Uno32 selected as the current board, you will get a lot of compiler errors.

I spent about an hour trying to figure out why I was getting all of the errors, and then realized that I had the wrong board selected.

The CAN demo included with the library does compile and run. (At least if did that last time I built and ran it).

The example provided with CANBus libraries use the standard mode, in my case I use the extended mode, but changing all references of SID to EID and try to compile it, generate hundreds of errors, the first says that the structure of such EID is undefined, but I searched and searched and can not find that file to redefine and to use extended mode ... Can you help me do it?

You could use the example in extended mode. Just can document the changes I made what I come up here for others to use.

Hi,

Where is the example code located please? I've grepped the MPIDE installation tree for canbus.h and not found it.

(Also, does the code work with the MX7cK please, as I'm considering using this for my project rather than the chipkit and network shield so I have a single board solution?)

Thanks,

Iain

I don't have the CAN bus shield, but I think you're looking the example which is in the chipkit CAN/ethernet library and is located here: http://www.digilentinc.com/Agreement.cfm?DocID=DSD-0000318

Enjoy! -Tim

Brilliant - thanks Tim, I'm downloading it now to take a look.

I am not using the CAN network shield, however I do have a boat load of 8 pin DIP MCP 2551 CAN transceivers, I am very eager to try this out with the chipKIT MAX32, but I am having a hard time trying to locate a schematic to hook up one or two transceivers. If anyone has access to a schematic so I can interface the transceiver(s) with the MAX32 I would greatly appreciate it and I will post back results. All help is greatly appreciated, thanks alot guys!

Hi , I am using chipkit network shield (max32) and I am running CAN examples from digilent. Is there any library support from chipkit ? Thanks!
