To create a file name I get the time from a RTC module.
Extracting the file to get the date. It looks like "20130222" as a string.
To make a directory with that name, I use the SD.mkdir() function.
So far so good. The question now is that it does not work.
I need to convert the string to a pointer
String DirName = getLabel(1,9); // this gives me the date as "20130222".
char *Dir = DirName; // this doesn't work. What code do I need ? Where to find it ?
Thanks for your time.
