Hello, I understand your need to go down till 100Hz, but the lowest frequency allowed by the STM32CubeMx configuration is 384Hz for Hrtim. Allowing such low frequency is not a common use case with STM32CubeMx, so I'm not sure that such modification w...

Hello, Yes, this sounds correct, if the computation of SET/RESET events could be done fast enough regarding the PWM period.Please, notice that enabling the preload of registers is a good practice, allowing the update to be taken in next update event ...

Hello, In order to synchronize all PWM, Master timer period (or compares in master timer unit) could be used as a reset source for other timer unit. This will ensure all timers roll-over at the same moment. Make sure also please to enable all Timer u...

Hello, Yes indeed, this feature is available for STM32G4 chip which contains an Hrtim version different from the one in h7. Best regards.

Hello, The HRTIMER counters can operate in Up‐Down counting. This mode presents advantages for fixed switching frequency power converters. The HRTIM is natively designed with up-counters. It offers however an operating mode with up-down counters, als...
