Regarding CCS CHIP registers

Hi Asmit,

all you need to do is include the c6x.h header file. That's where the Chip level registers are defined.

Example:

/*
 * main.c
 */
#include <c6x.h>

void main()
{
int val;

val =AMR;

}

Kind regards,

Hi

I have already included that file. And when I try the code given by you, error occures that symbol AMR could not resolve.

Hi Asmit,

please make sure that the header file is really found. You might need to add an include search path ...

Hi,

I am sure that code finds header file. There is no any error of header file missing or any other. If I use any other symbol of header file in code it directs to c6x.h file.

Hi Asmit,

if you open the c6x.h file you'll find the line:

extern __cregister volatile unsigned int AMR;

so AMR is clearly defined in there and should be resolved.

Maybe you can give us a little more insight about the exact error you receive.

Kind regards,

Hi,

Please see the file attached here. I have included c6x.h file and I am able to open it from .c file. The file is included, but I am getting syntex error in .h file at the line

extern __cregister volatile unsigned int AMR;

and that may be the reason why these all symbols could not resolve.

I have written code like NRP = 0xfcef;

... there's no need to delcare AMR again in the C code. Judst remove the line

extern __cregister volatile unsigned int AMR;

from your code.

Kind regards,

Hi,

I am not declaring it in C code. I am using AMR and other registers in c code. for example, NRP = 0xcd;

Hi Asmit,

the only thing you need is to include c6x.h to be able to access AMR and NRP.

It works quite nicely on my end. Please find attached a test project created with CCSv5.1

Kind regards,

hi,

I am getting the same error in the code given by you. Is this because I am using CCS 5.1.0009?
