MSP430FR5720: Sleep time measurement using RTC calender

rei

Hi,

I hope to check the time elapsed since sleep using the calendar function of MSP430FR5720.

For example, if I set the calendar for one day and wake up from GPIO after 10 hours, can I get the value of 14 hours from the RTC register?

Hi,

I'm confused by your question. Could you clarify your question about your configuration and expectation. Especially for below point.

1. set the calendar for one day ?

2. get the value of 14 hours?

Hi,

I'm sorry, I can't understand calendar mode.

I want to:

Sleep the MSP430 and wake it up after a few days. Is it possible to measure sleep time?

For example, set the alarm to 10:00 every day.

If it wake up at 9:00 from GPIO, can I check the remaining time (1 hour) until the alarm?

Hi,

You could read the registers of RTC to detemine the time of your weaking up.
