Amit, As I was looking into your problem, I ran accross a problem of my own! I am unable to open a watch window in the DSK5416 CCS IDE. I don't have the option for it in the View Menu, nor do I have the toolbar button. What am I missing here. Back to your problem. I don't seem to have the problem you are having. How did you come to the conclusion that the values are wrong? Did you see wrong values in a watch window? Did you look at the memory locations where the array is stored? Or some other way. Just for kicks, try moving your "myarray" initialization statment outside of main(), and see if you have the same problem. Let us know what happens.

Amit- You just say "error". When you expect -1.04, what value do you actually see? I don't normally use floating-point libraries in C54x code, but I might guess is that one possibility is that some type of 16-bit fractional notation is enabled. In that case the range would be something like -1 to +0.999969 (or -1 to 32767/32768).

hi thanks for ur mail. sorry about the typo in my mail. yes i have the curly brackets in the original program. but the problem persists regarding the incorrect values in the variable once it encounters a negative one or lower decimal value. did u experience such an anomaly before? hope to hear soon thanks --- Tony Zampini <> wrote: > Hi, > > I think you want to use curly braces instead of > square braces > when you initialize arrays.

Hi, I think you want to use curly braces instead of square braces when you initialize arrays. For example: float myarray[7]={-0.67,-0.89,-0.34,-1.04,-1.34,-1.67,-0.89}; How did you get away without getting a compiler error???

Hello everybody, I am looking forward to any suggestions for the problem i am currently facing with Code composer studio 'c5416 ver 2.10.05 for the TMS320VC5416 DSK. I am using a few pre-initialised arrays in the program and though the arrays are defined as float values, whenever the value goes lower than -1(negative one), the corresponding values stored in the array variables are in error. example: include files: dsk5416.h,stdlib.h,stdio.h,dsplib.h,tms320.h void main() { int i; float myarray[7]=[-0.67,-0.89,-0.34,-1.04,-1.34,-1.67,-0.89]; float myaction[7]; float mudata; .... for(i=0;i<7;i++) myaction[i]=myarray[i]*mudata; .... } in the above sample when i am checking the values stored in the variable "myarray" during the execution of the program, the values are in error starting from the fourth value corresponding to -1.04. All other values after that are also in error. kindly suggest if there is something which I am missing. thanks in anticipation. sincerely, amit j.
