Label:After MySQL was updated to 5.6.4, a new feature called factional seconds was added to record the millisecond value of the time. However, the current database does not log the millisecond value, so it generates a problem in which the milliseconds over 500 of the time in Java will be rounded. For example, a time is 2015-08-31 23:59:59.520, milliseconds value more than 500, when the storage, time will become 2015-09-01 00:00:00. The results are shown in the following two SQL lines.

STM32 internal watchdog settings STM32 has two watchdog, the IWDG internal watchdog is introduced here. Clock Source: Internal 40KHz clock, independent of the system clock. As shown below: The FSOC here is IWDG real clock. (Iwdg_prescaler_xx refers to the XX frequency division). IWDG Reload Value Register: RLR is a 16-bit register, only low 12bit can be used, other reservations. So the maximum value of the overload is 0xFFF That is, from the IWDG maximum from 0xFFF to 0 and then if not fed t
