Hi folks.

While playing around with some I2C stuff tonight(let us never speak of that other thread again!

), I wrote a little snippet of code for manipulating time$ into either AM or PM display if you prefer a 12Hr clock, which I do.

It might be of use to someone. Let me know if you see where the code could be improved, but it seems to do all that is asked of it.

CLOCK:
Print Date$,Time$ 'Show current system date and time
Print:Print 'Blank lines
X=Val(Mid$(Time$,1,2)) 'Calculate VALue of 'HOURS' from current time
If X>12 Then 'Time is PM...
H=X-12:AP$=" PM" 'Subtract 12 from current hour and set AM/PM indicator and space
If H<10 Then 'Hour needs a leading zero...
HOUR$="0" + Str$(H) '...so add one
Else
HOUR$=Str$(H) 'Hour is double-digit, so just turn that into a string
EndIf
Else
H=X:AP$=" AM":HOUR$=Mid$(Time$,1,2) 'Time is AM...
If HOUR$="00" Then HOUR$="12" 'If midnight, set hour to 12
EndIf
AMPM$=HOUR$+Mid$(Time$,3,7)+AP$ 'Build new time$ variable
Print AMPM$ 'Show new AM/PM clock.

Thanks Groggy, quick question, Does this code require Pull Up Resistors...
/Me Ducks and runs very fast...

Looks good :)

Cheers

@ Chris - I was being sarcastic in that post above - I was not being snooty towards you or anything.

I can take my medicine. If you can't laugh at your mistakes and take others jokes about your mistakes, then life just isn't worth it anymore!

It's all good value and fun, and I am not offended by anyone taking the micky about that other thread - I deserve it.

I doubt that I will forget to triple check the pull-up resistors again with I2C for as long as I live.

......but I digress.......Edited by Grogster 2015-10-10

The Typo Bob and I were referring too was that my original post had an I in the word Duck :) I knew you well enough to know you wouldn't take offence or I wouldn't have pulled your leg in the first place.

Okey dokey, thanks.

Just checking.

Sometimes easy to be misinterpreted.

Hi everyone,
Have used this code which is similar to that of @Grogster.

clock:
hour = VAL(left$(TIME$, 2))
min = val(mid$(time$,4,2))
sec = val(right$(time$,2))
ho = hour
if hour = 0 then ho = 12
if hour >12 then ho = ho - 12 'format for 12 hour time
if hour <12 then ampm$ = "AM" else ampm$ = "PM" 'format for 12 hour time AM or PM
hou$ = str$(ho,2,0,"0") 'format hours with leading zeros
mi$ = str$(min,2,0,"0") 'format minutes with leading zeros
se$ = str$(sec,2,0,"0") 'format seconds with leading zeros
ti$ = hou$ + ":" + mi$ + ":" + se$ + space$(1) + ampm$ 'ti$ is new time variable
lcd 1,C20, ti$ 'send time to lcd display
ireturn

Seems to work quite well on my desktop clock, hopefully will be of use to someone.

Gogster,
Did you try the clock at lunchtime?

You need to make allowances for that first hour after midday when it is 12:xx

What to do with midday and midnight is always a problem.

H=X-12:AP$=" PM" 'Subtract 12 from current hour and set AM/PM indicator and space

END

I think all the various possibilities are covered.

Jim, yes I did spot that lunchtime error, but ignored it - I wanted to see how long it took for someone else to pick up on that.

"Not long." is the answer.

Yeah, if I issue 'time$="12:34:50" or similar at the command prompt, then call the CLOCK routine, it shows as "12:34:50 AM" I think, and that is totally out by 12 hours.

I will try your code.
