Posted on May 17, 2011 at 13:55Sorry for not clarifying, this is what I want to do, I need to get the PC clock via usart and use RTCsetcounter=PCclock. After, I need to save the Time and voltage in the sensors per second for a span of a minute or so.
For now, I can only transmit time and 5 ADC values via usart and display them in hyperterminal. I can also set time manually by using USART_Scanf where it can only type numbers.
Here's my configuration code:
main()
{
while(1)
{
Timeshow();
}
/*******************************************************************************
* Function Name : Time_Regulate
* Description : Returns the time entered by user, using Hyperterminal.
* return : Current time RTC counter value
*******************************************************************************/
u32 Time_Regulate(void) //input time
{
struct tm t;
time_t t_of_day;
printf(''\nYear:'');
t.tm_year = USART_Scanf(2038)-1900;
printf(''\nMonth:'');
t.tm_mon = USART_Scanf(12)-1; //Number of months since January. [0-11] Go figure.
printf(''\nDay:'');
t.tm_mday = USART_Scanf(31);
printf(''\nHour:'');
t.tm_hour = USART_Scanf(24);
printf(''\nMinutes:'');
t.tm_min = USART_Scanf(60);
printf(''\nSeconds:'');
t.tm_sec = USART_Scanf(60);
t.tm_isdst = 0;
t_of_day = mktime(&t);
printf(''\n'');
printf(ctime(&t_of_day));
printf(''tday = %d'',t_of_day);
//printf(''time(0)=%d'',time(0));
return(t_of_day); //Return the value to store in RTC counter register
}
/*******************************************************************************

void Time_Adjust(void)
{
RTC_WaitForLastTask(); /* Wait until last write operation on RTC registers has finished */
RTC_SetCounter(Time_Regulate()); /* Change the current time */
RTC_WaitForLastTask();

printf(''\n\rTime: %0.2d:%0.2d:%0.2d\r'',THH, TMM, TSS);
printf(''\n\rred=%0.2f blue=%0.2f green=%0.2f \n\ryellow=%0.2f orange=%0.2f'',Vred,Vblue,Vgreen,Vyellow,Vorange);
