Yes I did read the manual - several times and I've spent 3 days trying to sort this
TIME$ = "HH:MM:SS" Sets the time of the internal clock is what it says in the manual
What I want to do is simple (in theory)
1) Get time from GPS ***DONE***
2) Decode time into hours, mins, secs, year, month, day ***DONE***
3) Set TIME$ from data hours:mins:secs ****** CANNOT GET THIS DONE****
I cannot figure out how to set the TIME$ from the time received from the GPS
The reason I want to do this is the GPS will only be powered on once a day to save battery power and I want it to update the TIME$ once a day
sounds simple but I can't figure out how to do it, and I can't find any threads with a similar scenario

Thanks Peter, it didn't work but it gave me enough clues as to how to fix it
I had to do time$ = Line2$
**Line2$ is the current time decoded from the GPS
Now another puzzle
I want to do this
Pin(26) = 1
IF TIME$ is between 02:05:00 and 02:05:30 THEN
PIN(26) = 1
NEXT IF
I can't figure out how to get the "between the 2 times to work"
OR if I was to simply put IF TIME$ = 02:05:10
would the Micromite check the time every second to see if that was the time? or am i best doing what I originally wanted - the time between 2 secs of seconds?
EDIT I did test it with the following code but it came up with an error
[261] If Time$ = 10:50:05 Then
Error: IF without THEN
[code]IF time$ = 10:50:05 THEN
PIN(26) = 1 'GPS Power turned ON
secs = 0
end if[/code] Edited by lew247 2016-06-30

Just try
IF time$ = "10:50:05" THEN

alternatively, convert times to seconds then just do standard compare
eg. hour, minute and second strings to numbers then seconds plus minutes x 60 plus hours x 60 x 60... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it!

It needs to be:-
[Code]IF time$ = "10:50:05" THEN[/code]
Or you could do use the TimeSecs Function I mentioned in another thread.
Cheers.

Another way is to use the SETTICK
from the MM manual p.27:
RTC GETTIME ' set the time at startup
SETTICK 12 * 3600000, SetTime, 4 ' interrupt every 12 hours
< normal program >
SUB SetTime ' interrupt called every 12 hours
RTC GETTIME ' reset the time
END SUB
Please replace the "RTC GETTIME" with your GPS routine.causality ≠ correlation ≠ coincidence

you are getting confused between numbers and strings. Strings are sequences of ascii characters that may, of course, include the ascii representation of a number.
Variables with a $ are strings. To assign a literal to them you include the ascii sequence in quotes
e.g. time$="11:11:11"
A number can be converted to a string using the STR$ function. It is also converted automatically using a PRINT statement.
works perfectly if hours, mins and secs are numbers but not if they are strings.
It is really worth trying to fully understand the three datatypes that MMBasic on the Micromite supports:
strings
integer numbers
floating point numbers
If you put the following at the top of your program:
OPTION EXPLICIT
OPTION DEFAULT NONE
It will probably cause multiple errors as it forces you to declare each and every variable and define its type. However, it is IMHO an unconditional truth that doing this is best programming practice.
If you do this you will fully understand what each and every variable is and which functions apply to it.
So VAL(string$) converts a string to a number (integer or float)
str$(number) converts a number to a string
etc.

Thanks everyone
[code]
IF time$ = "12:15:00" THEN
secs = 0
end if[/code]
did exactly what I wanted
Peter your right I do get confused, it's because of the brain injury/surgery I have problems remembering things, and quite often I have to "learn" certain things such as the difference between numbers and strings when I haven't used them for a while (or didn't fully understand it anyway
There are days when something so simple as saying PRINT TIME looks like
magazeti wakati$ in Swahili
but I will get there - learning slowly, sorry for so many questions and always asking why something wont work!Edited by lew247 2016-06-30

This is really stupid
It's been working perfectly with the above code
IF time$ = "12:15:00" THEN
secs = 0
end if
However today I changed the time to [code]IF time$ = 02:20:00 THEN
secs = 0
end if[/code]
02:20:00 and now it will not work
it comes up with the error
[code]
[261] If Time$ = 02:20:00 Then
Error: IF without THEN
>
[/code]
Anyone know Why this is happening?
Nothing else has changed in the code other than me changing the time
and it's been working perfectly for the past 3 days with no problems

Don't forget the qoutes as it is a string!
[code]
IF time$ = "02:20:00" THEN
[/code]

Thanks Jean
That was the problem - working fine now arghh will I ever get the difference with string$ and numbers!

Just think of it in there terms:-
ABC or "ABC" is a string; it's letters.
123 is a number.
123x2=246, another number.
"123" is a string, just like "ABC123".
Just like you can't multiply "ABC" by 2, you cant multiply "123" by 2 if it's a string; it's designated as a "Letters & Numbers" value.
If you wanted to multiply a string of "123" by 2, you'd need to convert it to a number first.
[Code]
> Print "ABC"*2
Error: Incompatible types in expression
> Print "123"*2
Error: Incompatible types in expression.
[/code]
If a string can be converted to a number, VAL() will return it.

lew247 Here is a little trick I use when staring myself blind on a simple statement that "should" or "ought" work. I use notepad and carefully line the staements in question up under each other.
This way I try to avoid to have 'remember' it more becomes a 'comparison' this has saved me a few times, the example earlier:
[code]
IF time$ = "12:15:00" THEN this one works
IF time$ = 02:20:00 THEN now this one does not work
[/code]

Although comparing for equality (to the second) won't hurt much(worst case scenario the clock won't update for three days running), consider doing it properly.
1) Power GPS module on when time is greater than whatever time you have picked.
2) Set power pin to 1
3) Loop until you either have the new time from GPS, or 5 minutes have passed on the current clock (again using greater than)
4) Set power pin back to 0
Log the number of:
a) successful updates
b) failed updates
c) total seconds gained
d) total seconds lost
Send these to COM port every minute or hour, or whatever works for you.
Anything more is gold plating (not necessary). But turning off the GPS once you have your fix makes sense.
