Writing to the CAN controller registers for the 2837xD microcontroller

Other Parts Discussed in Thread: TMS320C28346, CONTROLSUITE

Hi,

I wrote some old code for the TMS320C28346 microcontroller/DSP and am now using the TMS320F2837xD.  I'm trying to reuse my CAN bus code.  However, I noticed that the Ecan.h file that defines the CAN registers on the 28346 does not exist for the 28377.  

E.g. 

And I can't find that for the F2837xD: 

It seems like the other peripherals are in place but I can't find the header file for the CAN registers.  Am I missing something?  Does TI plan to write the file to help users program the CAN registers?  

I am unfamiliar with the methods used in the following: 

C:\ti\controlSUITE\device_support\F2837xD\v130\F2837xD_examples_Cpu1\can_loopback_interrupts\cpu01\can_looback_interrupts.c

It seems inconsistent with the other examples.  

Thanks,

Rick

    Rick,
    the F2837x - CAN module (DCAN) is totally different from F2833x (ECAN) in terms of the register implementation, register access methods, handshake between CPU and CAN-CC etc. Also, a "driverlib"-approach is used in the controlsuite examples for the F2837x -devices, which avoids bitfield accesses to control registers.
