Other Parts Discussed in Thread: MSP430FR5739, MSP430WARE

Hi,

I am trying RTC code in MSP430FR5739
I modified the example code msp430x54xA_RTC_01.c for the above controller but i am not getting proper output.

If anyone possible to share working example for MSP430FR5739?


I used 32.752Khz Crystal and 12pf capacitor

    Hi Karthik,

       There is an example in MSP430Ware: HERE

        Look at the Libraries, find Driver Libary for the MSP430FR57xx, and then open up the Example Projects for RTC_B:

     

     

       Best,

    No wonder. The 54xxA does have an RTC_A module while the FR5739 has an RTC_B module, which is a bit different.

    And is it properly running? The RTC_B directly utilizes the crystal, while the RTC_a uses ACLK which has fallback to REFO on 54xxA.
