interrupt @ 6hrs

Hello, For my data logger project , I must store temperature values at every 6 hrs. I observe that ticker maximum time is 30 mins. Is there any way we can make interrupt at long duaration like 6hrs or 10hrs??.

Thank you.

Unfortunately timers in mbed are limited to 72 minutes. You can either re-attach the Timeout after that (easiest), or use the hardware timer on your board using the native functions for your target. For example, STM32 RTC (see page 15-17) can be configured for up to 48 days. That'll be non-portable code though and you'll need to dig through the datasheet for the chipset you're using.

Hello Mohan,
If you are looking for scheduling of events using the built-in RTC and interrupts then have a look at the RTC library. In case you wouldn't mind using a Ticker driven clock then the Clock_Hello demo may give you some idea how to do it.
