Rtc time difference in stm32

WebStm32f0xx has three types of low power modes. In stop mode, the real-time clock is powered by LSI (low speed internal) clock source. HIS (High speed internal) and HSE (External) clock buses are turned off. The power regulator is in low power mode. The regulator in low power mode means flash is also in power-down mode. WebThe RTC on the F103 is a 32-bit counter, typically counting off seconds. You can slew it faster or slower with the prescaler. At 32-bit the second rollover would occur in ~136 …

WebAll timers require a clock of some sort. Most will be connected to the microcontroller’s main CPU clock (others, like real time clocks, have their own clock sources). A timer will tick (increment by one) each time it receives a clock pulse. In this demo, we will be using an STM32 Nucleo-L476RG, which has a default main clock (HCLK) of 80 MHz.
