STM32 Counter Mode Example – Frequency Counter | Timer In Counter Mode. by Khaled Magdy. In this article, we’ll be discussing the timer module operation in counter mode (STM32 Counter). How to configure a timer as a counter, and what are the possible configuration options.
A timer module can also operate in a counter mode where the clock source is not known, it’s actually an external signal. Maybe from a push button, so the counter gets incremented every rising or falling edge from the button press. This mode can be advantageous in numerous applications as we’ll discuss hereafter.
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.

In this user guide, we will discuss how to configure STM32 Blue Pill timer module in counter mode. To use the timer as a counter, we will configure it in input-edge counter mode. In input edge capture counter mode, timers of stm32 start to count whenever an external event occurs on the input-edge capture GPIO pin.
Counter mode: can be count-up or count-down. For count-up: the counter will count from 0 to the value stored in the Auto-reload register (Counter period) and then generate an Overflow interrupt and start all over again from 0.
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.
Introduction to timers for STM32 MCUs. The purpose of this document is to: Present an overview of the timer peripherals for the STM32 product series listed in Table 1. Describe the various modes and specific timer features, such as clock sources. Explain how to use the available modes and features.
