I have been developing firmware for a few years using STM32CubeIDE v1.8.0. I've been using the STLINK-V3MINI, which has been disconnected. I've since been using the STLINK-V3MINIE. I have had some issues with these. I recently updated the firmwar...

What is the maximum electrical drive frequency that the ST provided firmware can achieve with the STSPIN32F0B IC? And/or maximum RPM for a 5 pole pair motor?And the same question for the STPIN32G4....For a target frequency of about 1.5 kHz, what wou...

When using STM32CubeIDE, it is easy to inadvertantly make changes to source files that are up on the screen, often as a result of the focus being on the wrong window when one types. (This can easily happen when debugging, e.g. I have the focus on a ...

I have intermittent problems in STM32CubeIDE 1.8.0 opening a .ioc file. When I double click on the file in the Project Explorer, I get a progress bar titled "Loading IOC". When things are working well, as soon as that bar fills up, it is replaced w...

I have a project in a workspace in STM32CubeIDE, generated with STM32CubeMX. I would like to duplicate the entire project, including the .ioc information, to use as the starting point for a new project. How can I do this? I am amazed that this top...

Thank you Cedric, that was very helpful. Two more questions:1) Given modern sensorless algorithms, is there any benefit to having Hall sensors *for performance at higher speeds*? I know that Hall sensors help with startup and maybe with low speed o...

I would think that the maximum PWM frequency would just be determined by the PWM perhipheral that is part of the MCU. But maybe you are combining multiple steps here--I think it's actually the time it takes the CPU to execute the FOC algorithm that ...

The RPM depends on the number of poles, but the starting point is the maximum phase waveform frequency, which depends on what the FOC algorithm can sustain. This is not directly related to the PWM frequency.

This is for the case of using FOC.And, would using a sensored rather than sensorless BLDC allow higher speeds to be achieved? What would be the numbers?
