This will enable the ‘update’ interrupt for the timer. Note that as we did not configure interrupt controller, the interrupt won’t affect our code execution and we’ll have to check for it manually. Replace the contents ofmain()with the following code: InitializeLEDs();InitializeTimer();...
HAL_TIM_Base_Start_IT(&s_TimerInstance); From the main() function you can check the status of the ‘Update’ interrupt and toggle the LED state when the update happens: for(;;){if(__HAL_TIM_GET_FLAG(&s_TimerInstance, TIM_FLAG_UPDATE)!=RESET){__HAL_TIM_CLEAR_IT(&s_TimerInstance...
STM32CubeMX Tutorial Series: Basic TimerFrom Waveshare Wiki Jump to: navigation, search 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...
When configuring the STM32 Blue Pill timer module in encoder mode, the timer module works as a digital counter using two input signals. When both input pins have a valid transition, the counter gets clocked. The count pulses are generated by monitoring the sequence of the transitions of the ...

I'm trying to get a Timer Interrupt example working by following this tutorial: lostwire.wordpress.com/.../ But I run into some definition problem, error as: CubeProjectOne Configuration\CubeProjectOne Configuration.axf: Error: L6218E: Undefined symbol HAL_TIM_Base_Init (referred from main.o...
As we have seen in the last STM32 Blue Pill UART tutorial, In the polling method, microcontroller will do nothing except polling the state of the RX pin. Therefore, it is kind of a waste of microcontroller processing time and resources. On the contrary, by using an interrupt-driven approac...

SysTick is a special timer in most ARM processors that’s generally reserved for operating system purposes. By default, SysTick in an STM32 will trigger an interrupt every 1 ms. If we’re using the STM32 HAL, by default, SysTick will be used for things like HAL_Delay() a...
