If Alarm.delay(1000) is causing you a problem because it blocks your code for 1 second then you should consider reducing the delay time or better, only calling Alarm.delay() when it will not interfere with the operation of your program, or both, of course.

I think should be better reduce the delay maybe ...

because otherwise how can the timer start ?

Thanks

Hi Oliver,
you have exactly center my ideas ... :-)

So:

 - N°Dev --> are the number of the devices
 for example: I can set up timer for the devices from 0 to 7 ...

 when I setup the timer from a menu do this:
 - pass the menu value to:
    a) a timer
    b) in eeprom
    c) array (copy of eeprom)
 in this way if the electricity will be down automatically a timer will be set again if wrote into the eeprom.
 The first thing that the software do is read eeprom and pass the value to a local array that is identical to   the eeprom.

Then my ideas is change dynamically a timer from a menu ... make sense for you ?

thanks gnux

right now I have this out put for the time if you try the sketch:

 +DATE/TIME 1                           
 +DEVICES 2                             
 -TIMER 3                               
[  SetTimer 3-1                         
s
Start    01                       
:              01                       
 ok            zero                     
 back             

But I would like to have the outoput for the timer in this way:

 +DATE/TIME 1                           
 +DEVICES 2                             
 -TIMER 3                               
[  SetTimer 3-1                         
s
Sel Dev: 01 E/D: 0
Start: 01:01 + date (need to implement again because i want to do step by step)
Stop:  01:01 + date (need to implement again because i want to do step by step)
Ok Zero Back

I think is related to the hierarchy mention by you :-) but i need to take more feeling with that :-)

is possible from your point of view ?

Thanks for the support and have nice week end :-)

Hi

I think there is some missunderstanding of the GRIDLIST. I would suggest to read documentation about it. Maybe you could instead of the GRIDLIST use the XYLIST, which might be simpler to use. With the XYLIST you must provide the left position of each child element, which lets you create more easily the menu  element.

I can set up timer for the devices from 0 to 7 ...
TimeAlarms only normally allows up to 6 alarms to be set concurrently.  You can change a line in TimeAlarms.h to increase the limit.
Code:
#define dtNBR_ALARMS 6   // max is 255

Thanks to you guys :-) I will read the documentation for the menu :-) and I will try your suggest ...

So thanks also for the allarm is important Know how many alarms is possible set ...

Hi Oliver,
today after hours of I've build the menu ... I've understood how to use x,y list ... but now there is a little problem ... so I've available a lcd 20x4 ... well with my sketch i need more over di 4 rows ... with the sketch that I've did I've note that if i add more of 4 columns the display start to have some issues ... below reported the code ... so from my understating the code is correct: the problem is that with 20 character available, what I've understand is that i cannot put time and date only one rows ...because using x,y in cannot format the field ...then If not wrong this is the calculation :

start date: [000][000][000][000][000] --> totally characters used: 27 (without label and separator) then i need to split on more rows ... :-(  do you know If id possible fix it ?

if try to copy and paste the code you should understand perfectly what I mean :-( in attachment screenshoot also ... thansk for the support ... now i start to understand better also the tutorial is more clear now ...
see in the timer menu ;-)

Thanks for the support :-)

Hi
All number fields have a format option to limit the number of digits which are displayed.

See here: http://code.google.com/p/m2tklib/wiki/elref#U8NUM

The relevant part is this:
Format Options
    c: Number of digits, e.g. "c2" allows numbers between "00" and "99". Note, that this setting must fit to the min and max value.

This means you get the following results
Code:
M2_U8NUM(el,"c3",0,255,&number) --> "[000]"
M2_U8NUM(el,"c2",0,31,&number) --> "[00]"
M2_U8NUM(el,"c1",0,9,&number) --> "[0]"
The "c" format option is the key to format the output.
For your xy-grid you need to combine everything:
M2_U8NUM(el,"x0y1c2",0,31,&number) --> "[00]" at position (0,1)

Hope this helps,
Oliver

Hi Oliver :-), thanks for the useful information ,

i was see the tutorial :-) but and I was guess that was possible combine the value :-)

but I was pass the value into the wrong way :-) thanks in this way  I think I can stay with the four row :-)

The concept to mix the format is always good ? thanks gnux ;-)

Hi Oliver,
so now the output is like this :


Dev:[000]  E/D:000                     
 01  01  01  01  13                     
 01  01  01  01  13                     
 Zero    ok   back                     

I think is not Bad ... what do you think ? How do you will improve this ?

Hi Oliver,
I've play very well with the new function that I've learned ... so now I was working on the display time ... I don't understood why I cannot show nothing if I arrange the menu in this way...

Code:

uint8_t dt_day_disp = RTC.get(DS1307_DATE,false);
uint8_t dt_month_disp = RTC.get(DS1307_MTH,false);
uint8_t dt_year_disp = (RTC.get(DS1307_YR,false)-2000);
uint8_t dt_min_disp = RTC.get(DS1307_MIN,false);
uint8_t dt_hour_disp = RTC.get(DS1307_HR,true);

M2_LABEL(el_dt_l1_disp, "x0y2", "ddmmyy:");
M2_U8NUM(el_dt_day_disp, "x7y2c2r1", 1,31,&dt_day_disp);
M2_U8NUM(el_dt_month_disp, "x11y2c2r1", 1,12,&dt_month_disp);
M2_U8NUM(el_dt_year_disp, "x15y2c2r1", 0,99,&dt_year_disp);

M2_LABEL(el_dt_l2_disp, "x0y1", "hhmm:");
M2_U8NUM(el_dt_hour_disp,"x7y1c2r1", 0,23,&dt_hour_disp);
M2_U8NUM(el_dt_min_disp, "x11y1c2r1", 0,59,&dt_min_disp);

M2_ROOT(el_dt_ok_disp, "x0y0", "ok", &top_el_expandable_menu);



M2_LIST(num_list_date_disp) = { &el_dt_l1_disp,&el_dt_day_disp,&el_dt_month_disp,&el_dt_year_disp,
                           &el_dt_l2_disp,&el_dt_hour_disp,&el_dt_min_disp,
                           &el_dt_ok_disp
                          };
M2_XYLIST(el_list_date_disp, NULL,num_list_date_disp);


and issues is related to this:

Code:
uint8_t dt_day_disp = RTC.get(DS1307_DATE,false);
uint8_t dt_month_disp = RTC.get(DS1307_MTH,false);
uint8_t dt_year_disp = (RTC.get(DS1307_YR,false)-2000);
uint8_t dt_min_disp = RTC.get(DS1307_MIN,false);
uint8_t dt_hour_disp = RTC.get(DS1307_HR,true);

now the question that i did to my self and that I forward to you is ... ? Ok I've set a read only field ... but how can I retrieve dynamically date / time and put it on a display ... ?

so i think to have follow your suggestion maybe correct if wrong :-)

thanks 1000,

This is explained in tutorial 8: http://code.google.com/p/m2tklib/wiki/t08
When you jump from your toplevel main menu to the date/time entry you need to call a special procedure (prepare_user_input()) which reads data from external sources and puts them into variables which are shared with m2tklib.

If you would use a list of M2_BUTTON elements as toplevel menu, then the callback procedure for the M2_BUTTON should
(A) read the data from RTC and (B) refer to the date entry menu by using setRoot() procedure.
Tutorial 8 uses M2_STRLIST instead of M2_BUTTON, but the idea is the same.
