double vs. float

Hi Clyde,

Are you using the latest version of CCSv4 (4.2.5)? I believe it has been resolved in that version. There is also no issue with my CCSv5.1 install.

Thanks

4.2.5 seems to have no issues either

I have tried Code Composer 5 ... found Code Composer 5 bugs when compiling MSP430 code.

Are you indicating that your Code Composer 4.2.5 flags double as an error?

If not, then are you indicating your results are different from my results?

I do not get any error. Application compiles fine and the value of the double type variable ("dx" in your example) is as expected.

Could you attach a small, reproducible test case? Also let me know what version of the compiler you are using.

Thanks

A zip file containing the code and image is attached.  The contents of the code are:

#include <msp430f5529.h>
void main(void)
{
  WDTCTL = WDTPW + WDTHOLD;
  double dx = 15;// ... result: dx equals 0.
  float fx = 15;// ... result: fx equals 15.
}

I'm using version 4.2.4.  Is there a way to update only Code Composer 4?  The last time I selected update, it install Code Composer 5 along with a bunch of other programs I did not want ... burned a few hours deleting them and restoring Code Composer 4. 

Hi Clyde,

Thanks for the zip, esp the screenshot. Could you try flipping the format for the variables for 'hexadecimal' to 'natural' or 'decimal' and see if it says '15.0' for dx? I am seeing this behavior myself - it says 0 for hexadecimal for 15.0 for decimal. When I look at memory via the memory view, it seems to have the correct value. Looks like CCS is not properly displaying double types when the format is hex in the locals view.

You can download the 4.2.5 patch separately and then do a local update. You can get the patch from:

http://processors.wiki.ti.com/index.php/Download_CCS#Code_Composer_Studio_Version_4_Downloads (look under the 4.2.5 entry)

Thanks

This problem should be reported to the appropriate people.

I downloaded and started the install ... it appears to install everything, not just a patch, so I aborted ... don't want to lose all of my settings.  Is a patch available?
