PIC32 and RTCC
I'm developing control panel using PIC32MX530 and OLED. Right now working on Time/Date adjusting for users.
My question - what kind of protection you suggest against stupidity, for example if user will try to set 31st of February? There are two options for February (28 or 29 days), how can i know many days will be in February in selected year.
And second question - can RTCC detect exact weekday in case if I set only year, month and date right after power up?
Thank you in advance.
