MSP430 CCS Date/time functions

peg

Hi,

I would like to convert a string date from something like "YYMMDDHHMMSS" to a seconds time stamp (unix like), then convert it back to string.

Is there any "simple" way (library, source code ...) to do that on the MSP430 with CL430 compiler ?

In advance thanks

Hi,

Google is your friend. The discussion below shows an implementation in C using standard library calls (mktime and gmtime):

http://www.daniweb.com/software-development/cpp/threads/159524/how-to-convert-unix-time-stamp-to-syatem-time-stamp

An algorithm to do this is described in the thread below:

http://www.autohotkey.com/community/viewtopic.php?t=2633

And an interesting page with a few timestamp routines.

Hope this helps,

Rafael

Hi,

Ans thanks for this first answer.

Maybe i was not enough precise in my first Post.

I would like these functions on a MicroController unit MSP430 (no time management library as over Linux or Windows). The only source i found was the glibc sources, but i could see that these libraries are very heavy for a small micro-controller ! ...

So my question is ther some simple library or source code on this platform to make (Timestamp=>String / String=>Timestamp). EVEN with some small approximation about lead year, seconds etc ... The only thing i found is the commercial one for Crosswork ... is there same kind of library but with CodeCompser Studio and cl430 ?

Any clue ?

Then you are unlikely to be satisfied with the solution we have to offer. And that solution is to use the standard C RTS functions mktime, gmtime, etc. I am not aware of any other library for such tasks.

Thanks and regards,

Thanks George,

In fact, I should try to use the rtslibrary as you suggest and analyse the consequent size/performance overload.

Please could you confirm that the only way then most optimal way to use few of these functions is to include <time.h> and link with rst430.lib ? But there is many of it in msp430/lib ? eh, x x-eh, lc ...

In advance thanks,

That is correct.

For information about that, please see the section titled Including the Runtime-Support-Library in the MSP430 compiler book.

Thanks and regards,

OK, Thanks for all.

I will try all this and verify the overload (Flash, RAM, CPU time).
