Getting Started with STM32 - Timers and Timer Interrupts
Note that the only thing we have in there now is HAL_TIM_Base_Start_IT(&htim16), which starts the timer in interrupt mode. The while superloop is blank!

HW timer configuration using FreeRTOS
When you enable FreeRTOS, it wants the FreeRTOS to have a timer as well as a timer for the HAL modules. Typically, the ARM SysTick timer is used for the FreeRTOS. Now, just define a timer for the HAL to use. The HAL just needs a free-running timer to make timing measurements, it will use an interrupt to allow the timer to increment a 32-bit variable. (The F103 ony has 16-bit timers) The STM32F103C8T6 is a 48 pin device, and as such, only has four timers. 4 16-bit timers: TIM1, TIM2, TIM3, TIM4 Of the four, TIM1 has the most features. I would save that timer for "other things" Use one of the "General Purpose Timers", TIM2 - TIM4 for the HAL. (I usually use TIM4) This is configured in the "Pinout & Configuration" tab, System Core -> SYS -> Timbase Source -> TIM4 Good luck ! More on reddit.com

June 25, 2024Correct way of setting a 1μs timer on a STM32 MCU with HAL
The problem with your approach is that it will fail once other stuff is going on in the background. I'm assuming 84MHz is your CPU clock. So if you're not checking the flag for 84 CPU cycles, you miss one beat. 84 CPU cycles is not much. An ISR servicing USB could easily take more than that. So unless you are disabling interrupts before calling microDelay() your delay will not be precise. The approach of making an actual 1MHz counter and using its count is the correct approach and you should use it. As for the issue of calling delay_us with a value higher than the counter period, usually you would set up the counter to count from 0..1 million to match the MHz frequency, so you cannot pass a value that's too high because the argument is only a uint16_t. I must add that I'm not familiar with __HAL_TIM_SET_COUNTER/__HAL_TIM_GET_COUNTER. I'm just assuming that the value range here would be 0..1 million. More on reddit.com

Looking at the timer file stm32f0xx_hal_tim.h, we can see a sea of library functions near the end, most of them for advanced features. For this simple example, we just need HAL_TIM_Base_Start_IT() to start the timer interrupt.

November 18, 2023 - After the Timer configuration, click on NVIC Settings and Enable TIM6 global interrupt because we will toggle the LED using non-blocking (interrupt) mode. Then configure the GPIO B Pin 5 as output. We will connect our LED to this pin. In this NUCLEO board this PB5 pin is also connected to the D4 pin like Arduino. HAL_StatusTypeDef HAL_TIM_Base_Start_IT(TIM_HandleTypeDef *htim) API is used for timer initialization with interrupt mode.

STM32 Interrupts and Timers - HackMD
December 7, 2022 - Well that's because timers are generally more flexible and our main program can do other things while it waits for the timer to finish counting like this modification of the infinite loop above: ```c= while(1) { if (pressed) { TIM2->EGR |= (1<<0); // Reset timer value TIM2->CR1 |= (1<<0); // Enable timer while (TIM2->CNT < 1000) { // While CNT is below 1000 if (TIM2->CNT % 100 > 50) { GPIOA->ODR |= (1<<5); // LED ON } else { GPIOA->ODR &= ~(1<<5); // LED OFF } } GPIOA->ODR &= ~(1<<5); // LED ON pressed = 0; // Clear Semaphore } } ``` What this does is left as an exercise to the reader :) ## Example: Timers as Interrupts Perhaps more importantly, timers can be used as interrupt sources.

You have direct control over TIM1_UP_TIM16_IRQHandler. It's part of user code. If you don't want HAL_TIM_IRQHandler, hijack it there, check your flags, do whatever, and skip out on calling HAL_TIM_IRQHandler. · · If you feel a post has answered your question, please click "Accept as Solution".

Switch to NVIC settings and select TIM1 update interrupt. Go to Project Manager. Set the project name (TIM1). Project location. Type of toolchain (CubeIDE). Generate code. The timer is now configured but not yet started. For this, use the function: HAL_TIM_Base_Start_IT.

Controlling STM32 Hardware Timers with Interrupts – VisualGDB Tutorials
February 4, 2014 - The g_pfnVectors table contains addresses of interrupt handlers such as TIM2_IRQHandler(). Furthermore, unless you explicitly provide a method for a given interrupt handler, such as TIM2_IRQHandler(), GCC will automatically substitute it with DefaultHandler() that will halt your program. You can download the full source code of this sample here: TimerDemo.cpp · To learn about controlling the STM32 timers using the HAL API, follow this tutorial.

I ran into this with an STM32F105. The STM32F1xx Standard Peripheral Library functions are a bit different than what you are using, but the idea should be the same.
Issuing the TIM_TimeBaseInit() function caused the TIM_SR_UIF flag to become set. I haven't gone back yet to figure out why. Once this bit is set, the interrupt will trigger as soon as it is enabled.
To fix it, after calling TIM_TimeBaseInit(), I immediately called TIM_ClearITPendingBit(). Then I would enable the interrupt with TIM_ITConfig(). This fixed the problem.
My complete initialization routine looks like this:
// Enable the peripheral clock
RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM5, ENABLE);
// Configure the timebase
TIM_TimeBaseInitStructure.TIM_Prescaler = 1;
TIM_TimeBaseInitStructure.TIM_Period = 35999;
TIM_TimeBaseInit(TIM5, &TIM_TimeBaseInitStructure);
// That last function caused the UIF flag to get set. Clear it.
TIM_ClearITPendingBit(TIM5, TIM_IT_Update);
// Configure so that the interrupt flag is only set upon overflow
TIM_UpdateRequestConfig(TIM5, TIM_UpdateSource_Regular);
// Enable the TIM5 Update Interrupt type
TIM_ITConfig(TIM5, TIM_IT_Update, ENABLE);

Based on the solution from programmersought.com
Clear TIM_SR_UIF flag before every HAL_TIM_Base_Start_IT() call
#define FIX_TIMER_TRIGGER(handle_ptr) (__HAL_TIM_CLEAR_FLAG(handle_ptr, TIM_SR_UIF))
...
void myfunc(){
FIX_TIMER_TRIGGER(&htim7);
HAL_TIM_Base_Start_IT(&htim7);
}
Tested on STM32F407 Discovery board.

I think “NVIC_DisableIRQ(TIM7_IRQn);” just disable the timer's interrupt but not stop the timer. You may need: "TIM_Cmd(TIM7, DISABLE);" instead of “NVIC_DisableIRQ(TIM7_IRQn);”

Using [HAL][1], start:
HAL_TIM_Base_Start(&htim);
HAL_TIM_Base_Start_IT(&htim);
Stop:
HAL_TIM_Base_Stop(&htim);
HAL_TIM_Base_Stop_IT(&htim);
Where _IT is for timer interrupt mode. And you can reconfigure timer after stopping it.
