CAN interface on MCF51AC256

flameman — Thu, 30 Jun 2011 04:02:53 GMT

is there any Application Note about CAN interface of the MCF51AC256 microcontroller ?

Just to get started about the CAN AREAD interface: i need a piece of code which is able to initialize the can with a proper baud rate, and then i need to be able o send and get messages without using interrupts

any good code to be started with ?

If you go here:

MC51AC Tools

And look under "drivers" there is sample CAN code....

What CAN registers are missing?

5.8.0 is just IDE version. In IDE about box you should click Installed Products to see what development studio you are using. Latest classic CW for MCUs V6.3 comes with 5.9.0 IDE. Since 51AC are quite new, maybe there was some changes in header files. It should be mentioned in CAN driver what CW version it is compatible with.
