Posted on March 09, 2009 at 11:01Hi,
I'm a bit.. desperate.. I have a STR 715 (ofcourse with built-in RTC) with 32.768Khz crystal. So... It should work.. But, it doesn't.
I'm using the following code to initalize the RTC for every second an interrupt (ripped from the ST-example-code. =) ).
Code:
/* Configure RTC prescaler */
RTC_PrescalerConfig ( 0x8000 );
/* Clear Pending Flags */
RTC_FlagClear ( RTC_OWIR );
RTC_FlagClear ( RTC_AIR );
RTC_FlagClear ( RTC_SIR );
RTC_FlagClear ( RTC_GIR );
/* Enable RTC IRQ channel */
EIC_IRQChannelConfig( RTC_IRQChannel, ENABLE );
EIC_IRQChannelPriorityConfig( RTC_IRQChannel, 1);
EIC_IRQConfig( ENABLE );
/* Enable Second Interrupt */
RTC_ITConfig( RTC_SIT, ENABLE );
RTC_ITConfig( RTC_GIT, ENABLE );
The problem is; no interrupt will be generated.. Not one.. Not for a second, or ten seconds.. It just never goes into the RTC-ISR..
I've copied everything from the ST code examples. Checked and double-checked everything.. And I don't know why it refuses to handle the ISR. :S. And it drives me crazy.. :S
I'm using Keil uVision3 with keil compiler V2.41
Any ideas?
Thnx
Jay Kay.
