Hi,

I am new to using timer.I did go through the example codes given by TI,but i couldnt generate a 1 sec delay using timer since the max.value i can count upto is 65535.

Could i get some help on how to generate a i sec delay using interrupt.

Hi Divya,

You can use RTC with 32.768kHz clock to get 1 sec delay. Please refer to the example code msp430fr60x7_rtc_01.c .

Merry Christmas!

Hi Winter,

In the example code msp430fr60x7_rtc_01.c,the LED blinks every one second continuously.

Is there any method,such that the LED blinks every second until its one minute after which it should exit the ISR?

Best Regards,

Have the ISR count to 60, then turn off the IE. (RTCAIE, maybe? I don't have a copy of that example here.)
