RTC and spin how to set?

mctrivia

I am having trouble with getting an RTC to work with my prop.

I have the RTC object defined as:

rtc : "DS1302_full"

rtc.setDatetime( _month,_day, _year, _dow, _hour, _min, _sec )
however when I run
rtc.readTime( @_hour, @_min, @_sec ) 'read time from DS1302

I get 65,65 back for hours and min

and when I run

rtc.setDatetime(8,13,2010,6,14,29,0 ) 'month, day, year, day of week, hour, minute, second

it still reads back 65,65

I am using the sparkfun RTC Module. Any ideas what is wrong?

Sparkfun's module is a DS1307.

Use my driver in the OBEX.

I downloaded http://obex.parallax.com/objects/420/ and change object to


rtc : "DS1307_RTCEngine"


the folowing returns all 0s

rtc.readTime
_hour:=rtc.ClockHour
_min:=rtc.ClockMinute
_sec:=rtc.ClockSecond 'read time from DS1302
_day:=rtc.ClockDay
_month:=rtc.ClockMonth
_year:=rtc.ClockYear
_dow:=rtc.ClockDate 'read date from DS1302



this seems to do nothing:

rtc.writeTime(0,10,17,13,6,8,2010 ) '(second, minute, hour, day, date, month, year)



before first time accessing clock I run this:

rtc.RTCEngineStart(29,28,-1)



??? help

Did you use pull up resistors? The code works.

Use the built in demo. It tells you what is going wrong.

ah there is only 1 pull up. will try adding second.
