No worries, I'll surely report back on the RTC - samples are on the way but unknown delivery date at this time. It won't be used on this deployment test but may be on future improvements to the...
Thanks for info. I'm wondering how much devices will be recovered...
Also please report your experience with microcrystal RTC. I have one dev board on shelf, but newer tried...
Thanks for the info, that's a nice looking bit of kit you've produced there. I'll look up the manufacturer of those connectors and see if some $$ can be saved on the usual subsea...
Bill, Here is the connector I used on my TUBSUB project for COHO fishing. I have used it to depths of 250Ft. with NO leaks. I hope this might help for your future builds.
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...
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...
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...
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...

This is an effort to help users understand how the I2C command works by comparing it with SHIFTIN/SHIFTOUT. A serial EEPROM, 24FC1025 will be used in the example.
