Hi Leigh,

Just a quick question with regards to the RTC Battery Back-up.

I have inserted a 2032 Lithium battery in the Miac and I assume we can't keep calling a RTC Set-up Macro as it will keep defaulting the RTC Clock to the time we have set in the Macro. How can we call the RTC set-up once and not again so we don't overwrite the time each time the MIAC Switches off?

Regards,

Gavin

Hi Gavin,
The RTC setting is usually done via a setup menu selected via the keypad.

Thanks Leigh!,

I have written the Time part of the RTC keypad working nicely, just the date side and I will run some tests..

Thanks Leigh!,

Working nicely now - thanks again for the help!

Hi Leigh,

I have the time working nicely, the date is an issue, I can't seem to get the last digit for the Year on my routine, somehow I have tried it a Million ways and still nothing. Any help would be greatly appreciated.

The routine is not very polished just playing about but somehow If I enter 10/01/19 in the key pad I can only get 10/01/1

Many Thanks...

Regards,

Gavin

Hi Gavin,
You are getting on well
The simulation debugger is very useful for helping with these kind of problems.
If you set a breakpoint in your GET_DATE, run the simulation, when it stops on the breakpoint add DATE to the variable watch.
You can then edit the value of DATE to help see what is happening ...
Then Step to the next icon and see how the DATE changes ...
So this is the fix ...
Hope that helps
Leigh

Thanks Leigh,

The Simulation really, really helps!,

I still can't seem to see the 2?

I used the calculation in Date Set as:

DATE[5] = '5'
DATE[4] = '4'
DATE[3] = '3'
DATE[2] = '2'
DATE[1] = '1'
DATE[0] = '0'

I used the Calculation as

DATE[8] = 0
DATE[7] = DATE[5]
DATE[6] = DATE[4]
DATE[5] = '/'
DATE[4] = DATE[3]
DATE[3] = DATE[2]
DATE[2] = '/'
DATE[1] = DATE[1]
DATE[0] = DATE[0]


And attached is what I get

The RTC:SetDate string should only be 6 characters and without the '/'

Hi Leigh,

I did do that?, perhaps I have miss-understood you?

Could you try it on the hardware now?
It could be that the RTC component does not simulate.
If hardware does not work, could you post your latest project file?

on the Display I get when I run the code:

01/03/45

Ah, I think that might just be the RTC component doing some checking,
i.e. there is no month 23

Oops how embarrassing as I should've seen that...

thanks Leigh - all working!
