i did the same connections shown in the shematic , downloaded the same program (that is displayed here) inside PIC16F628A, gave 5VDc and checked the connections again. But i didn't see anything on LCD.......

I even added a variable resistor (10 K) for the contrast of LCD and fixed the light in the middle position.

SO now, you will keep on saying that i have to read datasheets??

or you will try to help me in an effective way?

i finished my MEMS laboratory and sent it to canado to be manifactured :-D

Friday i will present it in front of jury and MONDAY..... i'll graduate :-) and since then, i'll pass a whooooooole month in the Carribean!

But right now, since i am used to pressure of work, i'll continue and work on this real time clock. But not now.... during the last month i was sleeping only 4 hours daily and then, working 20 hours on this project non-stop , with just 30 minutes of break for each day.... imagine this situation!!?

so i will just sleep......

Please guys, take it into consideration and check that schematic and program... tomorrow i'll be well awake so i'll concentrate on your replies and try to accomplish what you told me to do..

But please, please , please........ stop talking about datasheets...

By the way:

"The California Dept of Fish and Game is advising hikers, hunters and fishermen to take extra precautions and keep alert for bears while in the Yosemite and Mammoth areas.

They advise people to wear noise-producing devices such as little bells on their clothing to alert but not startle the bear unexpectedly. They also advise carrying pepper spray in case of an encounter with a bear. It is also a good idea to watch for fresh signs of bear activity and know the difference between black bear and grizzly bear droppings. Black bear droppings are smaller and contain berries and possibly squirrel fur. Grizzly bear droppings have little bells in them and smell like pepper spray." :-)
