No, I'm using the internal 32k crystal to maintain the time with the basic timer. The accuracy is not critical, and when the main battery is replaced (~6years), the time would need to be corrected for the time it takes to replace the battery. I'm using it for a datalogger output. As you can probably tell, I can't stand to use 500uA to 2mA for active mode usage (as the DS1390 uses). I also don't even want to loose 60 to 175uA as this is almost 1/2 of the overall system current. It looks like from the datasheet, the function of the time.h functions is already built in to the chip as everything is accessed in component parts (H:M:S;D:M:Y, etc). I'm maintaining the UNIX time variable (this is very easy), but need an easy way to have a human enter that time (and I don't think telling them to go to a converter and get the number is viable).
Thanks for the idea tho. -Mark -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Garst R.

What sort of input device are you using to enter the time? I use the DS1390, and set the time when I programm the MSP. It can be off by a few s due to the programming time, but the RTC will stay up for about 11y. If you are doing something similar, I can probably help.
