The STM32 Timer example program shows how to configure and use the timer TIM1 of STMicroelectronics STM32F103xx microcontroller. TIM1 is configured to generate an update interrupt every 250 ms. The lit LED moves on every timer tick. The configuration of
Timers can be used to trigger a variety of interrupts (see section 72.2.9 of theHAL/LL API reference documentfor a list of possible HAL-supported interrupt callbacks). We will use a very basic interrupt: when the timer reaches its maximum value, it will rollover back to ...

Abstract: STM32 has powerful timers, including basic timer, comment timer and senior timer. In this chapter, we will introduce the basic application of the timer: How to use timer interrupt to control the LED blinking with interval of 1s. In this chapter, we will use the GPIO project des...
