MSP430F5529: MSP320F5529 RTC 32-bit counter mode

Konstantin Beloff

Part Number: MSP430F5529

Hello,

I am trying to implement a millisecond counter that can operate for 24 hours without overflow. The purpose is to create time stamps for event log with distinguishable milliseconds. No external clock source available.

RTC in 32-bit counter mode seems to be the only option, but I couldn't find any examples on how to set it up. Can you please share some or suggesto some other way to solve the problem?

Regards,

Konstantin

    Hello Konstantin,

    To use the RTC_A in the MSP430F5529 in counter mode, please refer to the example provided in the Driverlib example project folder in the TI Resource Explorer. There you will find an example which shows you how to properly configure the RTC_A in counter mode.

    For further detail regarding the RTC_A peripheral, please refer to Chapter 22 of the MSP430F5529 User's Guide which gives a detailed description of the peripheral and also shows which registers are used to configure it.

    Best regards,

    Matt
