HRTIMe1 Interrupt needs HRTIM-MASTER Interrupt to fire?
I saw similar issue in GitHub but it pertains to Source of fault.
Anyway, I am using STM32G4 V1.3 on STMcubeIDE V1.5.1 on win10 machines (2 PCs)
It seems that HRTIM-E1 will not fire up the interrupt unless I enable HRTIM-MASTER and its interrupt via CubeMX.
Here is the setup of HRTIM-E1:
in main()
HAL_HRTIM_WaveformOutputStart(&hhrtim1, HRTIM_OUTPUT_TE1 );
HAL_HRTIM_WaveformCountStart_IT(&hhrtim1, HRTIM_TIMERID_TIMER_E );in MX_HRTIM1_Init()

/* USER CODE END HRTIM1_Init 2 */
HAL_HRTIM_MspPostInit(&hhrtim1);
}in CubeMX
Period to set the IO and COMP1 to reset it
I have the output, but it will not enter the interrupt.
I use another I/O to check whether it entered or not.
void HRTIM1_TIME_IRQHandler(void)
{
/* USER CODE BEGIN HRTIM1_TIME_IRQn 0 */
GPIOC->BSRR = (1<<11); // start
/* USER CODE END HRTIM1_TIME_IRQn 0 */
HAL_HRTIM_IRQHandler(&hhrtim1,HRTIM_TIMERINDEX_TIMER_E);
/* USER CODE BEGIN HRTIM1_TIME_IRQn 1 */
GPIOC->BSRR = (1<<(11+16)); // end
/* USER CODE END HRTIM1_TIME_IRQn 1 */
}If I enable MASTER HRTIM but disable NVIC call handler
void HAL_HRTIM_MspInit(HRTIM_HandleTypeDef* hhrtim)
{
if(hhrtim->Instance==HRTIM1)
{
/* USER CODE BEGIN HRTIM1_MspInit 0 */
/* USER CODE END HRTIM1_MspInit 0 */
/* Peripheral clock enable */
__HAL_RCC_HRTIM1_CLK_ENABLE();
/* HRTIM1 interrupt Init */
HAL_NVIC_SetPriority(HRTIM1_TIME_IRQn, 0, 0);
HAL_NVIC_EnableIRQ(HRTIM1_TIME_IRQn);
/* USER CODE BEGIN HRTIM1_MspInit 1 */
/* USER CODE END HRTIM1_MspInit 1 */
}
}
The interrupt would fire up as shown below.
CH1 yellow = HRTIM-E1
CH2 green = PC11
What's more troubling is that the postion of the interrupt would depent on the HRTIM MASTER interrupt source.
In this case, CMP1 and repetition will fire up HRTIM-E1 (but not "timer update").
Also CMP1 of HRTIM-E1 will be used in case CMP1 as the source for HRTIM-MASTER.
