Hello all,

I have a quick question for you.

When I boot the CMM2 it always asks for the keyboard and the time / date.

I have an RTC (and I did OPTION DS3231 ON and the battery is inserted) - so how do I avoid this constant asking for keyboard / time?

Thank you for any suggestions!

(I am running 5.07 as 6.00 does not work at all with my keyboard)

Thank you!

PS: I have a picomite too - but the CMM2 behaves not exactly the same, hence the questions

Yeah, I wish there was an option to bypass the time/date input altogether.

Means that no-keyboard embedded system would be dependent on a healthy battery.

This is normal? So why is there a battery powered clock if one needs to enter the time and date every time?

It is not normal. Your RTC is kaput, or battery is flat, or in upside down.

Note the batteries in the original CMM2 had an appallingly short life span. I don't know if that is still the case.

Best wishes,

Having re-read your initial post I think I know what is happening.

Are you using the default onboard RTC or have you installed the optional high resolution DS3231 module ?

If as I suspect it is the former then try OPTION DS3231 OFF.

Best wishes,

Tom
