Phases Voltage Sensing support MC Workbench STM32H755ZI

[Zeno]

Hi, 

Is the Phases Voltage Sensing already supported for STM32H7 MCU's?

[PN]: STM32H755ZIT3
[VERSION]: MCSDK 6.3.2
[TOOL]: MC Workbench + Board Designer
[DETAILS]:

I've noticed that with a custom board I created that there's a small error under the Project Hw & Info tab saying that the Phases VoltageSensing is not supported for the selected MCU. I also see this coming into the connectAlgo.log file: 

ERROR - Inverter Board: Following feature not supported by MCU: PhaseVoltageSensing
ERROR - Inverter Board: Following feature not supported by MCU: PhaseVoltageSensing 

This error seems to disable the HSO mode for theSpeed Sensing Selection although the feature is available on the inverter board:

[EXPECTED BEHAVIOR]: When the feature PhasesVoltageSensing is configured for an inverter board/MCU the HSO should become available for Speed Sensing Selection in the MC Workbench .

[HOW TO REPRODUCE]:

• Configure an inverter with STM32H755ZIx MCU and add the PhasesVoltageSensing feature under the motor feature.
• Use the inverted in a workbench project 
• See the error message under Project Hw & Info tab.

What does "not supported" mean in detail, what functions or configuration would be necessary to enable this for the H7 MCU?

Hello Zeno,

The reason why the PhaseVoltageSensing feature is not available for STM32H7 is that this feature is only useful for HSO, and that HSO is currently only supported on STM32G4. It is true that this is not specified explicitly anywhere, and we apologise for the confusion. Thank you for your report, we will try to improve that point in the future.
