how can i know the time with BS2 ?

farsad

dear friends:

i want to record some data with my BS2 every one hour (like a data logger). my problem is that i don't know when to recored the data and how i can use the BS2 clock for knowing the time. for example, in QBasic or VBasic there is a Time function which returns the current time and i can use it and collect my data every one hour. is there any similar function in PBasic?



thanks

You could do it this way:

start:

for x = 1 to 3600······· '= total pause of 1 hour
pause·1000········'= 1 second
next
'record data
gotostart

Well to accurately record / use date and time you will need to use an RTC (Real Time Clock)

the problem is that i can't pause my program for one hour because it has to work all the time and control a vacuum system.

Farsad,
Have a look at the parallax link above and here !

a brief wiki here ....

Basically its an I.C that will keep track of date/time even when the microcontroller or stamp is turned off.... Do post your findings !!
