Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi all.  I got my GEN2 unit from https://micromite.org/  and it is very nicely made.  He has included the 2 resistors for the PS2 mouse function and it seems he has populated the High Accuracy RTC but when I issue the Option DS3231 command it returns "Invalid Command"  Not sure what is happening there.  If the chip is not functional is that why that command does not work?  Otherwise, did I miss some change on that function or any issues with it?  Thanks

PS. I am on Beta 4

See the post "OPTION Errors".

Someone has what seems to be a similar problem, fixed by making OPTION DS3231 the last option set up.

OPTION DS3231 ON

You need the ON

It will cause a reboot

Yes after OPTION RESET and the ON it works just fine.  I have got to reread the new user guide all the way through again.  I Just put it on my kindle.   It is very nice of Phil to include the chip. Thanks.
