Can a timer module operate in counter mode?
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. And we’ll do a couple of practical LABs, first of which is a basic digital counter and the second one is a frequency counter mini-project.
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.
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.
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.
Aug 17, 2020 · A timer (sometimes referred to as a counter) is a special piece of hardware inside many microcontrollers. Their function is simple: they count (up or down, depending on the configuration--we'll assume up for now). For example, an 8-bit timer will count from 0 to 255. Most timers will “roll over” once they reach their max value.
It is possible to configure one slave timer to increment its counter based on a master-timer events such as the timer update event. In this example the master-timer event is signaled by
