Re: Using Counter IC

Yes, you can do this with a simple counter chip. There are plenty to choose from but I am still a little confused (extreme lack of data).

Everything you said up to the point that the signals come from a standard electronic timer...ok...but what do you mean when you say you want to retain the data? (maybe you just want to remember the current count?). You are being extremely vague or just not used to explaining yourself properly. Are you saying that you might want to maintain a total count of output pulses??? BTW, the word "data" implies that there is a quantity of information.

If this is the case then you need another counter to count those pulses I suppose. Still, a PIC is a better choice and you could retain "the data" in it's EEPROM. However, all this is useless unless you know what you want to do and that you can also explain it. Hint, detail a diagram perhaps, ask "yourself" questions such as;

1. How many inputs (inputs = actual physical signals) are required?

2. How long does the output need to be active for when it counts the pulses? (Multiple choice here: from 1usec -> 99hrs)

3. If the counter retains data then how will that data be used?

4. What power source are you using? (affects the choice of components)

5. Do you need to validate the inputs? (false pulses etc)

6. What is the worst case scenario and can you live with it? (always ask this one)

7. What questions would your worst critic ask? (consider them)

Using a PIC controller is a really nice suggestio and i have already
started work on that.

The signals come from a same source, a standard electronic timer.
I also want to retain the data for atleast 7 days. I am using a battery
for this purpose.
Can i do it with a counter IC?
