I work on a project with stm32l010f4 how can i use timers to create a delay i dont want to use HAL_Delay is there any code for this??

[MStab]

Look into HAL_SYSTICK_Callback... If I remember correctly this function is called once every ms, you can use this to implement a counter.

Put a TIM in a free running mode, ie 16-bit, maximal, 1 MHz

Then delta the TIM->CNT to measure if given number of micro-seconds have elapsed.

uint16_t a, b;

a = TIM2->CNT;

do

{

b = TIM2->CNT;

} while((b-a) < 123);

Use a low power timer for setting a min delay in microsecond.

extern LPTIM_HandleTypeDef hlptim1;
 
void LPTIM1_Init(void) {
  LPTIM_HandleTypeDef* hlptim = &hlptim1;
  // Set the LPTIM2 clock to PCLK because HSI16 is off
//  RCC->CCIPR &= ~(3<<20);
//  RCC->CCIPR |=  (0<<20); 48 MHz = MSI = APB
  HAL_NVIC_SetPriority(LPTIM1_IRQn, 3/*0*/, 0);
  HAL_NVIC_EnableIRQ(LPTIM1_IRQn);
  hlptim->Instance->CFGR |= LPTIM_PRESCALER_DIV16; // 3 ticks = 1 us
  /* Set WAVE bit to enable the set once mode */
  hlptim->Instance->CFGR |= LPTIM_CFGR_PRELOAD;// LPTIM_CFGR_WAVE;
 
  /* Enable Autoreload match interrupt */
  hlptim->Instance->ICR |= 0x0002; // ARRMCF clear flag  
  __HAL_LPTIM_ENABLE_IT(hlptim, LPTIM_IT_ARRM);
 
  /* Enable Compare match interrupt */
//  __HAL_LPTIM_ENABLE_IT(hlptim, LPTIM_IT_CMPM);
 
  /* Enable the Peripheral */
//  __HAL_LPTIM_ENABLE(hlptim);
}
 
void LPTIM1_SetTick_us(uint32_t delay_us) {
  LPTIM_HandleTypeDef* hlptim = &hlptim1;
  
  if((delay_us/3)>0xFFFF) TrapError(); // change the clock prescaler if looking at more than one milisecond
  if(delay_us==0) {
    // turn the timer event off
    __HAL_LPTIM_DISABLE_IT(hlptim, LPTIM_IT_ARRM);
    __HAL_LPTIM_DISABLE(hlptim);
    return; // done
  }
 
  /* Enable Autoreload match interrupt */
  __HAL_LPTIM_ENABLE_IT(hlptim, LPTIM_IT_ARRM);
 
  /* Enable Compare match interrupt */
//  __HAL_LPTIM_ENABLE_IT(hlptim, LPTIM_IT_CMPM);
 
  /* Enable the Peripheral */
  __HAL_LPTIM_ENABLE(hlptim);
 
  /* Load the period value in the autoreload register */
  __HAL_LPTIM_AUTORELOAD_SET(hlptim, delay_us * 3);
 
  /* Start timer in freerun mode */
  __HAL_LPTIM_START_CONTINUOUS(hlptim);
}
 
/*
void HAL_LPTIM_AutoReloadMatchCallback(LPTIM_HandleTypeDef *hlptim) { 
  // Timer is one shot mode, so it should trigger only once after kitstarted
  NOPs(1);
}
*/
 
 
void LPTIM1_IRQHandler(void) { 
//  HAL_LPTIM_IRQHandler(&hlptim1); // ==>   HAL_LPTIM_AutoReloadMatchCallback(&hlptim2); 
  
  /* Autoreload match interrupt */
  if(__HAL_LPTIM_GET_FLAG(&hlptim1, LPTIM_FLAG_ARRM) != RESET)
  {
    if(__HAL_LPTIM_GET_IT_SOURCE(&hlptim1, LPTIM_IT_ARRM) != RESET)
    {
      /* Clear Autoreload match flag */
      __HAL_LPTIM_CLEAR_FLAG(&hlptim1, LPTIM_FLAG_ARRM);
 
      /* Autoreload match Callback */
      Add_on_board_LPTIM1_Tick(&STModADD_On);
    }
  }  
}
