We will show it based on the STM32F4-Discovery board, however controlling the timers of other STM32 devices is very similar. What should also be done is starting the timer counting ( HAL_TIM_Base_Start_IT() function) and adding some extra code into the interrupt handler in order to change the output state of PD12 . I tried few other timers to check if there is no hardware problem, but no, it isn't. As long as you enable the interrupt by calling HAL_NVIC_EnableIRQ(), the timer will automatically trigger an interrupt handler function when the event occurs. As the result we get the new project with timer initialization function and interrupt handler. 0. It now supports 16 ISR-based . __HAL_TIM_CLEAR_IT(&s_TimerInstance, TIM_IT_UPDATE); © 2012-2020 Sysprogs OÜ. In my case, I'm using the low-layer drivers, so an example code would be: The problem is that I was using the LL_TIM_SetPrescaler(TIM16, 7999) and LL_TIM_SetAutoReload(TIM16, 2999) functions to configure the time base, and I discovered that when using these functions, the values weren't being updated, so I had to generate an event to update the values using LL_TIM_GenerateEvent_UPDATE(TIM16). stm32_hal_dshot Brief Dev Environment Library Features ESC Firmware and Protocol ESC Firmware ESC Protocol Dshot 1. General-Purpose STM32 Timers can generate an Interrupt/DMA signal on the following events: Update: counter overflow/underflow, counter initialization (by software or internal/external trigger) Trigger event (counter start, stop, initialization or count by internal/external trigger) Input capture; Output compare Easy. So I cleared all compare flags (from 1 to 4) in my "TIM2_IRQHandler" function by using folowing codes. This text fills that gap. This book provides a comprehensive description of the operation of the ARM core from a developer’s perspective with a clear emphasis on software. Step1: Open CubeMX & Create New Project.
