Problem in implementing examples on C6713 by Rulph Chassaing

Started by hassanjaleel July 12, 2006
Hello, I have the book of Dr Rulph Chassaing on DSK 6713, along with its CD
containg all the codes and support files. Now i am following the
instructions of the book to start implementing the starting examples
including "sine8_LED"and "sine_buff".I have included all the files and
libraries and followed the settings as mentioned in the book. How ever
when i try to build my project it creates three object files
"sine8_buff.obj,c6713dskinit.obj and Vectors_intr.obj" and then there are
4 errors 

symbol _DSK6713_AIC23_codecControlhandle is defined multiple times

symbol  _DSK6713_AIC23_codecdatahandle is defined multiple times

these errors occur once referring to the obj files c6713dskinit.obj and
sine8_buff and then referring to c6713dskinit.obj and
dsk6713_aic23opencodec.obj.

Since i am just a beginner in this field i have completely no idea what is
happening. So if any one knows the solution kindly tell me.It will be a
great help for me.

I can't promise to solve your problem instantly, but since I am sitting in front of Code Composer and a 6713 DSK right now and have Rulph Chassaing's software here also ... What source files _exactly_ do you have in your project? You should have _only_ c6713dskinit.c, sine8_buf.c, and Vectors_intr.asm, as per figure 1.10 in the book. Are you using Code Composer version 3.1.0? I am using Rulph Chassaing's software with it (as opposed to CCS version 2) for the first time and in order to get the sine8_buf project to compile I've made changes in the Build Options and to the locations of some support files. That said, I haven't seen and can't replicate exactly the error you describe. If no-one else solves your problem soon, email me a copy of cc_build_Debug.log, and I'll have a look at it. Donald
