Situation: new to BS, having a BS2 module
Task: log date and time upon triggered of sensor, 4 sets of date &
time per day for a week. Size ia a problem for this porject.
Doubts:
1. Can i achieve this without a Real Time Clock & External EEPROM?
2. Do i need to write/get a program that count year, month, day,
hour, min and download to BS2?
3. Any better suggestion?
Thanks pals, and have a nice day!

text. It discusses data logging with time stamping and uses a real
time clock, the DS1308. It may help get you started though you will
need to add code for date. The code in the text has about 300 bytes
left over in EEPROM for data to be logged into, and you may be able
to cut down some of the code or add additional eeprom to your circuit.

it seems to brobotics. Click on the 5.4M text beneath it.

Two that come to mind:

tm and www.high-techgarage.com. I've used both and they are both very
usable.

Look at the BS2P or the new "data logging Stamp" (forgot the
nomenclature). You can store things in unused program banks, which means
you can store quite a lot. Keep in mind though there is some upper limit
to how many times you can write to EEPROM (maybe a million cycles? Jon
can probably tell us the correct number). For programming this is
plenty. If you are writing to a single cell once a second, a million
seconds is less than 12 days! Four events per day would probably not be
much of a problem although you will eventually wear out.
