DS3231 ALARM

[kaqkk007]

Lately the DS3231 handling on pic bases has been getting worse , I had to change the settings many times before it would work . Today even resetting the update version does not help , it refuses to work . What could be the cause ??

I noticed that only pic16f628 won't start (with internal oscillator)

Hi

You need to include your chart illustrating the problem before we can assist.

This is the problem that is not communicating with the RTC.

Perfect in simulation but returns 0000 values "live"

The even values of the run variable are displayed ( BCD converter 74141 + digit outputs ) the odd ones are blanked ( 15 values and digit = 0 )

Hi

In your settings you have the clock set as RC Clockout not internal oscillator. Remember if using internal oscillator to include a c-code block at the very beginning of your chart to set the registers. The IntOsc Helper component will assist in creating the value.
