Hello,
I was wondering if there is any way to store or save some code information into my compiled code. I would like to use date of compilation to initialize a constant variable. Is there any macro which allow me to do that? I'm looking for a way to save automatically date of compilation or code version to be able to show it in my LCD device.
Thanks.

The C language has such a construct.
it is called "const"
it is considered good form to declare the type T and then add the modifier "const"
T const variableName

unsigned int const LCDVersion = 5;
unsigned char const Title[] = "Greatest Application";
similar to these are the __DATE__, __TIME__, __FUNCTION__, __FILE__, __LINE__, ...
these are pre-processor defines in GCC. If you are using another compiler, you will have to check that they work.
printf("%s\n", __DATE__);

so something like
unsigned char const BuildDate[] = __DATE__; // might work for you, if I have the types correct

Dan Saks http://www.dansaks.com/articles.htm has some useful articles about const.
