Hi all,

Could any of you please send me your linker cmd file which has IQmath sections to run the
program in RAM of F2812?  I also need IQmathLib.h file.

I need to know whether should we do any modification in the  IQmathLib.h file  other than
changing the IQ value to our desired global IQ?  

I also saw the definition for Floatmath is '1' and IQmath is '0' in the IqmathLib.h file, is it
correct if we run IQmath functions alone?

May i know the type and radix of IQ numbers which would appear in watch window.?
For my case, for example variable x is defined as global IQ 19, expected value to appear in
watch window is 2.02113, But I have got the following

_IQ(x)   1.0356e-06 (wrong value)   type is float, radix is float

I expected the type would be IQ and radix is float, can any one correct me? What modification
should i do to see the IQ numbers in watch window, all values look very strange to me.

Please respond me, I am having tough time, i couldn't move to further step without this.

regards

Hi Naayagi,
 
I'm not sure if I've understood your problem correctly. But from what you are observing the
watch window, i guess the problem is related to your IQ math variable radix definitions in the
watch window. In the radix colums, you can select  "q value" option and enter the
desired "Q" (in your case 19). Then, the value appearing will be as per the
justification required for IQ19 numbers.
 
Thanks,
Vishal
