Hi

I am doing a project in which i am using msp430g2553 and an external RTC PCF8563 ( which uses I2C interface). I want to know how to set date and time in the RTC to initialize it. And, is it possible to overwrite the content of RTC with a data which is received through UART ?

    Hi Princey,

    Chapter 17 of the MSP430x2xx Family User's Guide contains everything you need to know concerning I2C communication with the MSP430G2553: www.ti.com/.../slau144j.pdf

    This can be used in conjunction with chapters 8 and 9 of the PCF8563 datasheet for overwriting RTC addresses and reading from them, as well as setting alarms: www.nxp.com/.../PCF8563.pdf

    TI also offers several Launchpads that feature MSP430 devices with internal RTCs such as the MSP-EXP430F5529LP and MSP-EXP430FR5969 for your consideration.

    Regards,
    Ryan
