WebThe medium-density STM32F10xxx RTC peripheral consists of a chain of programmable counters consisting of two main units: the RTC prescaler block generates the RTC time base. Depending on the clock period applied to the LSE input, this prescaler can be adjusted to generate a time base (RTC_CLK) of 1 second by writing to the prescaler load register. our earth behaves like a hugeWebAll 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. roelof press
