Hi Suresh,

How are you calling sprintf() with the float values? Can you share your sprintf() line of code and I can take a look? 

Best Regards,

Delaney

Hi Delaney,

Greetings of the day.

Thank you so much for your response 

sprintf(mechanicalOffsetString,"Offset : %.3f \r\n",mechanicalOffset);
sendString(mechanicalOffsetString);

This is my line of code, where mechanicalOffsetString is my buffer of size 30. Even if I give a direct float value to my buffer in sprintf function, buffer is getting filled with some random values not the actual value. 

Expecting a quick solution

Suresh 

Hi Suresh,

Your lines of code look correct. Can you verify that you have --printf_support set to full in your project properties?

Best Regards,

Delaney

Hello Delaney,

Yeah, I have verified all the project properties and --printf_support already set to full, Char data is also not getting stored in my buffer if I give char data directly to buffer like data in double quotes " DATA " it is getting updated in buffer and printing that out. when I try to print the floating data by converting it to string / char data it is not working.

Hi Suresh,

Can you try the solutions listed in the thread linked here and let me know if it solves the issue?

Hi Delaney,

It is working with the format specifier %g and %e but the data after point at the 5th position or more going wrong. Up to 1.23456 it is correct but when one more digit added like 1.234567 then the last 67 getting changed. suggest the solution to get actual data and once verify with this float format specifier

Hi Delaney,

I have another issue, that is I am not able to program launchpad part no : LAUNCHXL-F2800137 using TI XDS110 Debug Probe (TMDSEMU110-U)  for this i followed a thread which is in forums but still iam not able to flash the program . Could you please help me to solve this .

Best Regards,

Suresh

Hi Suresh,

What exactly is the error your seeing?

For this issue, can you double click on the target configuration file and click "Test Connection"? If this fails, it means the incorrect target configuration file is being used or your board isn't connected. For the F280013x launchpad, you may have to switch to the TMS320F2800137_LaunchPad.ccxml if that's not already what you are using.

Best Regards,

Delaney
