TMS320F280049C: Problem when using CLA of 280049c

Foriner

Part Number: TMS320F280049C
Other Parts Discussed in Thread: C2000WARE

now i use 280049's CLA in our project, There are some compiler warnings that confuse me

when i do not add the cla and related header file, the project is build ok, but when i add the cla file , the build error is as follow:

i didn't define the __TMS320C28XX_CLA__ , when i shield "#ifndef __TMS320C28XX_CLA__" , the error is over and the project can build, but the warn is display as follow:

as i know the CLA of 280049 can operate the CAN module so the "bp_16/32" must be defined , how i can solved this problem? thank you!!!

Hi,

CLA doesnot have access to CAN, hence the above usage is not valid

Can you let us know what are you trying to achieve with CAN and CLA here?

In my project,The communication between modules is realized through CAN communication

and i used CLA to complete the algorithm of module control.

so i don't need the CLA to use CAN , but i just want the CLA and CAN functions are used simultaneously

how can i resolve this compatibility alert ? thank you !!

Hi,

Can you confirm if the file that you have used for implementing cla functions is named with .cla extension and the same is included in the project?

yes, the cla file is XXX_Cla.cla, and is in project

in XXX_Cla.cla head position, the include is:

and in f28004x_device.h we include can.h and bp_16 bp_32 define, but error is exist:

Hi,

Are you using the f28004x_device.h from C2000ware? In C2000ware, f28004x_can.h is only included under #ifndef __TMS320C28XX_CLA__

#ifndef __TMS320C28XX_CLA__

#include "f28004x_can.h"

#include "f28004x_dcc.h"

#include "f28004x_lin.h"

#endif

As Praveen mentioned, CLA cannot access CAN and CLA compiler does not support byte_peripheral attribute

thank you for you reply, according to your remind, i have solved the problem. as show below.and the error and warn is disappear

but i have a doubt: where define the "__TMS320C28XX_CLA__" , i never had define "__TMS320C28XX_CLA__"

is the CCS complier define "__TMS320C28XX_CLA__" automatically while i creat a "xxx.cla" ?

This is defined by the compiler for the .cla files. Since this headers can be used in both .cla and .c files, this macro can be used to differentiate the C28x and CLA specific content.
