A Timer Module in its most basic form is a digital logic circuit that counts up every clock cycle. More functionalities are implemented in hardware to support the timer module so it can count up or down. It can have a Prescaler to divide the input clock frequency by a selectable value. It can also have circuitry for input capture, PWM signal genera...
STMicroelectronics provides some different versions or variants for the hardware timer modules. STM32 microcontrollers usually have a handful of each type, however, some parts may lack one or more of these hardware timers. So, in this section, I’ll highlight those timer modules and their main features, block diagram, and things like that. Just to g...
An STM32 timer module can operate in any of the following modes, however, you should not assume that a given timer does support all of these modes. Instead, you’ll have to check the datasheet to figure out which modes are supported by which timers. As we’ve seen earlier, there are many groups of timers which include: General-Purpose, Low-Power, Hig...
After this long overview of the STM32 timers hardware variants and the timers’ possible modes of operations, we’ll just focus on one of them for the rest of this tutorial. Which is going to be the very basic one, the “timer mode”. So, we’ll discuss the timer mode operation in-depth and we’ll follow this up by a practical LAB in the next tutorial. A...
The purpose of this application note is to provide a simple and clear description of the basic features and operating modes of the STM32 general-purpose timer peripherals. This document complements the specifications of the STM32 timer peripherals available on their reference manuals.

Aug 17, 2020 · The STM32 line of microcontrollers from STMicroelectronics are no exception: each controller offers a full suite of timers for us to use. In this guide, I’ll show you how to configure a timer using STM32CubeIDE, use it to measure execution time, and set up non-blocking code.
Jun 27, 2024 · This is STM32 Timer Tutorial Part 1 – Bare Metal Part 3. In this tutorial, we are going to see all the registers that are available for the Timer/Counter in STM32. Then we will write a program for the timer.
The STM32 timers are very versatile and provide multiple operating modes to off-load the CPU from repetitive and time-critical tasks, while minimizing interfacing circuitry needs. All STM32 timers (with the sole exception of the low-power timer) are based on the same scalable architecture.
In this tutorial, we’ll discuss how to configure the STM32 timer module to generate timer interrupts with a couple of example projects (Timer Mode). You’ll go through step-by-step HAL example configurations to initialize all the required hardware peripherals.
