Hi All,
I want to set the RTC time to the current time and date without hard-coding it.
I tried to use the function time() and ctime() defined in time.h, but I read that time() is a semihosted function (http://www.keil.com/support/man/docs/armlib/armlib_chr1359122861930.htm)
#include <time.h> time_t rawtime; char buffer[50] ={0}; time(&rawtime); sprintf (buffer, "%s", ctime(&rawtime) );
So if I include time(&rawtime), then the program stops with BKPT 0xAB (indicating semihosting) and if I don't include it then the buffer displays 00:00 1 Jan 1970.
So my question is, how do I write the retarget.c to use the time function? I read a lot of examples on retargeting printf, but can't find anything on time().
Or what is the normal way of setting the current date/time?
Thank you.
And, yes - it's quite likely that the radio would connect to the main processor via a serial port of some sort.
Of course it is. That's why I posted the message.
Strange that you think you need to validate the statement.
