Guys I have a problem with DS3231 chip. Made a clock with a cheap Ebay module & it worked fine.
After 1 month of continuous run the time halted. After searching the internet found that the crude charging circuit & the battery gives lots of problems & need to remove the crude Li cells charging circuit on these modules. I modified the circuit & placed a new CR2032 battery.
The problem is in a good A/C condition (cool) the time works fine. At home (Hot) the time holds & not counting. The time increments sometimes very slowly.
I just guess does the Aging Register have some garbage values after my battery issue? Do you guys set this register when power up the chip?
