strftime, localtime TMS320F28335 Toolchain 6.4.6

Hello all,

I want to convert a variable of type time_t into a timestring in an Interrupt Service Routine like this way:

strftime( PrSealCheckDateStr, 19, ": %d-%m-%Y", localtime( &DateAndTime_t ) );

This works well, if I do this in the main loop. Now my question is:

Can I use the strftime and localtime function in an interrupt Service routine, when I use the functions in the main Loop, too?

Thanks in advance

    No.  Unfortunately, TI has no solution that supports concurrent multiple activations of localtime.

    Thanks and regards,

    Hi George,

    is there a list of functions that I can call in an interrupt and in the main program at the same time?

    Thanks in advance

    That line comes from my signature.  You only see it at the end of my posts.  Once you click Verify Answer on a post, then that button changes to show Reject Answer.  You can click Verify Answer on more than one response in a thread.

    Clicking that link means you no longer receive an e-mail when anyone posts to the associated thread.
