MSP430FR2633: RTC Calendar available?

James Wright98

Part Number: MSP430FR2633

I've gotten the RTC function to work with the FR2633, but can't seem to get an RTC Calendar library working along with it.

Using http://www.ti.com/lit/an/slaa290a/slaa290a.pdf , it seems like this changes the standard RTC clock timers I've set up and only updates the seconds once before stalling.

Is there a driverlib function that can be ported over to the MSP430FR2633?

    Hey James,

    I don't know of an RTC calendar library for the MSP430FR2xxx devices. Also, I'm unfamiliar with the RTC library refered in the app note but it seems the last revision was in 2011 which is before our first FRAM devices were released to the market. It hasn't been updated to support FR2xxx devices.

    We like keeping our App notes much more up to date that than that, so I've put this App note in the review pipeline to get it updated in the next couple months.

    I would like to mention that our MSP430FR5xx/6xx devices have built in calendar funcationality for their RTCs. I'll leave this thread open for now to see it anyone else has implemented a calendar mode on the MSP430FR2xxx.

    Thanks,
    JD

    Thanks for looking into the App note, JD.

    I've moved back to implementing a RTC calendar with the standard c library time.h. It's a bit of a resource hog, though.

    James,

    Thanks for the feedback and glad you have another path. When the team reviews the app note we'll see if it makes sense to try and add this type of funcationily for FR2xx.

    Thanks,
    JD
