HSO for two motors using the ST-G473 microprocessor in MC Workbench

kmce · ‎2026-04-21

Hi,

After reading HSO current and voltage sampling in three-shunt topology, I beleve it is possible to run two BLDC moters using the ST-G473 microprocessor using 2 ADC's per motor. However, there does not seem to be support for that in the MC Workbanch. Will this be available in the future?

Regards,

Kevin

Hello kmce,

It is indeed possible to run 2 motors with HSO theoretically speaking. However, as you mentioned, it is currently not supported yet. Despite being on the roadmap, I cannot provide any information on a possible release date of that feature yet. What can I say though is that dual motor HSO is not scheduled to be supported on STM32G4 at all. We are currently focusing on STM32C5 and onward for all new features.
