Trigonometric function using EZDSP F28335

Hi,

The sine function you're using above... might be defined in a header file which should be included in your project. Please check the same.

Hello Gautam,

I checked that as well. The sin.C is in located "C:\ti\ccsv5\tools\compiler\c2000_6.2.11\lib\src". I included that file in the "Include Options". However I still get the same error.

Ashish, try copying the file (sin.c) itself to your project. Let us know what you observe after doing so.

Dear Gautam,

I copied sin.c in the current project. It gives me another error saying value.h is missing since the sin.c uses the value.h

Please advise.

Ashish, very strange behavior! This means CCS is able to recognize physical files in the project but the linking is not working. Try switching to a new workspace.

Dear Gautam,

I tried in a new workspace. Here is the code.

/*
* main.c
*/
#include<math.h>
void main(void) {
while(1)
{
double a,b,c;
a=3.14159;
b=sin(a/4);
c=b;
}
}

I found one interesting thing. I put a breakpoint at (c=b;) line. And then run the code continuously till that point and getting the correct values for b. However, without breakpoint and debugging step by step it gives me an error

Can't find a source file at "/tmp/TI_MKLIBOyYjdM/SRC/sin.c"
Locate the file or edit the source lookup path to include its location.

Dear Guatam,

I re installed CCS (v6.1). It works absolutely perfect.

Thank you so much for your help!

Ashish

Excellent Ashish!

Goodluck & Regards,
Gautam
