In the STM32CubeMX there is a preload setting. If I enable the preload then I can see the update interrupts are working as expected. But, if the preload setting is set to disabled, then no update interrupts are seen. This is true for all timers A-F a...

Hi,I have enabled the interrupts for channel set (SETx1) and channel reset (RSTx1) by setting bits RSTx1IE and SET1xIE. I am trying to drive the outputs to active-inactive state via software by writing to SST and RST bits of the TIMERA.Inside the TIM...

The reason I ask is, the application note 'an5496-buck-voltage-mode-with-the-bg474edpow1-discovery-kit-stmicroelectronics' says the Buck_VoltageMode_SW.ioc is setup to be used with IAR workbench. However the same application note also mentions 'STM C...

Hi Amel,Thank you for your quick response.@Vincent Onde suggestion was when preload is enabled we have to ensure an update event is put in place such that interrupt flags are copied to the active register. But in this case, the preload option is dis...

Yes! This works.. Either I can configure the preload settings in the CubeMX to write to active register directly and it works, or if preload settings are set to write to preload register, then an update event does the job.

Hi Vincent,You mean to say the below bits?They are indeed set.Also, please note the below flags are set that tell interrupt occurred:

The Simulink Coder Support Package for STM32 is based on the ARM mbed. Since mbed does not have support for the Encoder, MATLAB/Simulink doesn't have a block for the same either. You can try connecting with MathWorks paid consulting for the same.

HRTIM on STM32G4 and STM32H7 "Update Interrupts" are not working when preload is disabled.

STM32G474 discovery kit HRTIM ISR (HRTIM1_TIMA_IRQHandler) not hit for channel set Interrupt(SETx1) and channel reset interrupt(RSTx1).

Hi, Has any one tried importing the 'voltage mode buck example project' as available for download here: www.biricha.com/ST-Discovery-Kit into the STMCube IDE?
