Log_info for a float?

Hi,

I am trying to log floating values but cant seem to figure out how to make it work..

I have tried:

Log_info1("float=%f",f);

Log_info1("float=%f",(IArg)f);

Log_info1("float=%f",floatToArg(f));

None of these seems to be working. I also could not find anything on the forums...

Thanks

Derek,

What device are you running this on?

Thanks,
Scott

Can you verify if you turned on support for floats? See here: http://rtsc.eclipse.org/cdoc-tip/xdc/runtime/System.html#extended.Formats
Are you getting garbled output or there is no output at all?

Hi,

Sorry for the late responce, but my junk mail has been eating these up.

I am using a f28069.

I tried to input the command: System.extendedFormats = String "%$L%$S%$F";

directly into my script file but it returned errors.

I am not entirely sure how to put that guy in there...

Thanks,

Derek

What are the errors?

If you are not referencing System in the script before that statement you need to add the following before you set extended formats:
var System = xdc.useModule('xdc.runtime.System');

Hello Derek,

I have the same problem with C6748LCDK.

I am using:

- CCS5.5

- SYS/BIOS 6.35.4.50

- UIA 1.3.1.08

- XDCTools 3.25.3.72

In the code:

int intData = 1234;

float floatData = 12.34;

Log_info1("Tekst %u",intData);

Log_info1("Tekst %f",floatData);

As a result of above in the Raw logs I get:

So %u works correctly, but %f writes to the buffer exactly "%f" instead of floating value. Where is the problem?

Mirek,
%f is not expanded in Raw logs. To see it expanded, you have to display it in the console window. Look at my messages in this thread for a detailed explanation:
