Hello everyone,I have PWM signals configured in HRTIM, which can phase shift with HRTIM master compares. The problem I am encountering is that, even having preload activated, phase shift can load at diferents periods of the master. The problem probab...

Hello everyone,I am generating PWM signals using the HRTIM module. Specifically, I am using Timer D to generate a PWM signal along with its complementary signal. This signal is always in phase with the master counter, setting at the timer period and ...

Hi all!I have NUCLEO stm32G474RE board, and I am playing with HRTIM.I am trying to take advantage of fault logic, found in HRTIM module.HRTIM can have GPIO hardware input, which can shut down all HRTIM outputs, without any software overhead.Now, I wo...

Dear team,I am using a STM32G474 in my application. I've generated a PWM in the HRTIM TIMER E that is active low (necessary for the requirements of the modulation). I want to insert a dead band between this signal and its complementary (Output 2). Th...

To solve the duty higher that 1 instead of doing the set in Timer period event, the PWM is set at CMP=0. Probably if I do the set with a master compare, it will work also.On the other hand, the error that i had when i phase shift exactly 0.5, was tha...

I take this effect into account skipping CR between 0 and that minimum, as I see you did it. The effect of doing this is minimal on the phase shift. I am more worried with phase shift transients that can generate unwanted voltage references during 1 ...

Now I have the set in CMP1=0 and reset in CMP2=HALFPERIOD. With this seems to not generate duty cycles greater than 1 period. Mcu.UserConstants=HALFPERIOD_MASTER,5230;PERIOD_MASTER,10460;INIT_MODULATION,2615 HRTIM1.ADCTrigger1_Source1=HRTIM_ADCTRIGGE...

The Preload in Master Timer is enabled and still happens. But I don't understant why if I change the set of the PWM to CMP=0, instead of the period, it works.

Thanks for the reply, but i solved this issue. ST has an option to define negative dead bands, this solved my issue.Best regards.
