touble with a time calculation

[longpole001]

in fact i have several clock timers running for this project , most are based on the master timer with other value settings to change the displayed results

for this task the time counter counts up from 0 , the set _time value is the length of time before trigging the overtime clock , which counts up to show the total amount of time exceeding the set_time values

when the main timer exceeds the set_time then a secondary timer ( overtime clock ) is enabled and then shows and continues to run until the main timer stops

as seen if the overtime clock values = main clock - set time , when a sec , min , hour roles over , a < 0 value will occur untill the time value = set_time value again

Yes that is exactly what your code does. I did wonder if that was what you wanted to do.

I was also thinking if this is necessary

if Days => Set_Day and Hours => Set_Hour and _
Minutes => Set_Min and Seconds => Set_Sec and _
100th => Set_100th then OT_Enable = 1

and what would be the implications of just having this

OT_Days = Days - Set_Day
OT_Hours = Hours - Set_Hour
OT_Minutes = Minutes - Set_Min
OT_Seconds =Seconds - Set_sec
OT_100th = 100TH - Set_100th



if Hours - Set_Hour <0 then
OT_Days = Days - 1
OT_Hours = 23 - Set_Day + Hours
endif

if Minutes - Set_Min <0 then
OT_Hours = OT_Hours - 1
OT_Minutes = 59 - Set_Min + Minutes
endif

if Seconds - Set_Sec <0 then
OT_Minutes = OT_Minutes - 1
OT_Seconds = 59 - Set_Sec + Seconds
endif

if 100TH - Set_100th <0 then
OT_Seconds = OT_Seconds - 1
Ot_100TH = 99 - Set_100th + 100TH
endif

Just a thought

yes ill start on the space problem thread later this week ,
can you PM me an example bit of code for the sd card , mainly how you append data to existing open file , indexed data reads example if you have it
