Timers
Timer peripherals are very important components within a MCU. Many embedded applications are time or temporal dependent and timers are the primary means by which the MCU controls the application. While it is certainly possible to use a MCU to directly time processes, it would be great waste of processing power and highly inefficient approach. Using hardware timers along with interrupts is really the only practical way to implement embedded time-dependent applications. Fortunately, there is a powerful timer variety provided by STM in its line of MCUs.
STM Timer Peripherals
A timer is simply a free-running counter that counts pulses from a clock source. Since the pulse train from a clock source has a known period or interval between ...
