Sometimes it bombs out , then it stop working.presss reset the it works normal
But the time is all zero
I get problem when working with real time ds 3231. Sometimes. It lost data then all time becomes zero
it is problem with I2C . I have tried serveral way to deal with i2c hang problem. but it cant solve.
