Problem with CAN and 18F258

[stgt]

Hello,

I use the internal CAN-Controller of the 18F258 and want to send data by CAN-Bus. If I try to compile, I get the follow error:

----------------------------------------------------------
Flowcode2.c

Return code = 1

Has anybody had the same problem maybe? Could anybody help me?

Thanks in advance

Hello

At the moment the CAN code is suited only to work with a Microchip MCP2515 CAN controller. We are looking into using the internal CAN controllers at the moment.

The errors you are getting are due to definitions of registers that exist for the internal CAN and also on the external MCP2515 chip.
