STM32F3 / HRTIM1 with Fault Interrupt

[Florian1]

Posted on October 26, 2016 at 10:05

Hello,

I'm using the

HRTIM1

to control a flyback converter.

The

FAULT5

input is used to stop the converter in case of an error. Now I want to use an interrupt service routine to react to the fault immediately. Therefore I've enabled the fault interrupt in my timer initialization:

HAL_NVIC_EnableIRQ(HRTIM1_FLT_IRQn);

I've also added the according interrupt handler routine:

HRTIM1_FLT_IRQHandler()

But the interrupt handler routine is not called when the fault is triggered. (I'm sure the fault input is working because the converter stops immediately). I'm also unsure which

HAL IRQHandler

must be called to branch to the according

HAL_HRTIM_Fault5Callback()

routine. Could you please help me to setup my system to call the interrupt and the callback routine in case of the fault? #hrtim-fault-irqhandler

Hi finsterbusch.florian, 

I recommend to get help to develop your HRTIM application from the following sources:- Application note

Likely needs the IT flag enabled on the TIM (peripheral) side
