error compiling floating point with CCS 3.3 for TI F28335 dsp - Joel_Prieto_Corvalán - May 19 19:39:11 2008



Hi!

I need some help to know what I am doing wrong.

I am a new user of codecomposer. We've bought at University a Technosoft kit
based on TI DSP F28335, that supports floating point operations.

When I try to compile this message is shown

There are errors

When I delete this section of code its compile well

It seems that it doesn't compile floating point operations.

Does anybody could help me with this problem?

Best regards,

i have not used 28335. this is my guess.
  if u are using sprc530 or the "hardware abstraction layer" or tidcs for 28335 then
just above your "examples" folder there should be something like  "common"
, "source" folder. there should be a file which deals with pwm generation. this file
might have the declarations that are missing in your project.
  find the right file, right click on your project and add the file
   
  hope this helps

Thanks chirag

I wrote technosoft about the problem. It seems that it is missed the librar=
y
that handles floating point operations. Because I =91ve tried a simpler
program and I still have the problem. I will write about the tests soon.

#include "..\DSP28335_Regs.h"

            z=3D56;
