Introduction to timers and their uses
Timers are crucial components in embedded systems, serving essential functions in a wide array of applications. In this section, we will explore the concept of timers, their types, and their various applications.
The question is, What are timers?
Timers are hardware peripherals found in microcontrollers that count clock pulses. These pulses can be used to measure time intervals, generate precise delays, or trigger events at specific intervals. Timers can operate in several modes, including counting up, counting down, and generating Pulse Width Modulation (PWM) signals.
The choice between using the SysTick timer and general-purpose timers on STM32 microcontrollers comes down to the complexity and precision of your timing needs. While the SysTick timer is great for simple system timing tasks such as generating periodic interrupts or creating delays, it’s limited in flexibility and features, as it’s often dedicated to real-time...
