Other Parts Discussed in Thread: MSPWARE

Hi,

I am using example code from MSPware and trying to run RTC, I have enable AUXVCC3 charging, As per my knowledge, AUXVCC3 gives supply to crystal, RTC and some part of RAM.

Here, My clock is running perfectly but RTC doesnt work. I dont want to connect external supply to AUXVCC3 (PIN no. 29).

Also I tried to measured voltage on AUXVCC3 pin but Its showing 0.3Volt.

Please reply ASAP.

Thanks

    BHavdipsinh,

    Please see the post below for your answer to this inquiry. Please also remember if you are using the charging circuit for AUXVCC3 to connect the appropriate capacitor or battery to the line. If no back-up supply is desired, please follow the documentation and TID example for conne3cting to DVCC.
