Re: Low power accurate 6 month timer - suggestions?

Hi Dave,

Thanks for sharing. Yes I don't have the luxury of a large battery... I'll look into other PICs but I'm not sure the WDT timing is accurate or reliable enough for any real confidence in...

Re: Low power accurate 6 month timer - suggestions?

If you use an 16F18326 like I'm using for my remote temperature sensor, and setting the WatchDog timer for the maximum of 18388608 or 256 seconds you can count to 60750 which is still a word size...

Re: Low power accurate 6 month timer - suggestions?

Hi Heckler,

One would like to think the pressure and humidity inside the vessel would remain as they were when it was sealed at ambient levels - anything other than this means there's a leak and...

Re: Low power accurate 6 month timer - suggestions?

If it is critical I would stay away from ebay suppliers. May get counterfeit or seconds (rejects)

What about temperature / pressure / humidity inside the vessel at the bottom of the ocean?

Re: Getting data from user, how to store it properly? (kinda dialog interface)

Might I suggest FM24W256 from RamTron. It is an EEPROM with NO write delay and 151 year data retention. I use them on quite a few of my products and have had NO failures at all. They also support...

Re: Getting data from user, how to store it properly? (kinda dialog interface)

I'm wondering if it may be beneficial to restrict the project to chips with EEPROM? It seems somewhat tedious to enter all those numbers... and then lose them with a loss of power - intentional or...

Thanks, what I'm trying to build is a programmable movie camera crane, for some cinematic action.

Re: Low power accurate 6 month timer - suggestions?

Thanks for the suggestions, for best flexibility I think sayzer's second method is the way to go although the first method is one to remember for other projects. That 4k monitor sounds good...

Re: Low power accurate 6 month timer - suggestions?

If you need low power, accurate, and small part I'll go with microcrystal RTC.
3.2x1.5x0.8mm, 40 nA @ 3 V, ±1 ppm @ 25°C, Fout 32768...to...1Hz, alarm with int pin.
Need more?

If you have room for coin cell and that pic then you probably have room for

it has 2 alarms on it which I think will do what you want, it...
