Motor control workbench 6.1.1 custom board creation

[prigh.1]

Dear All,

I would like to update old projects from workbench 5.Y.2 to workbench 6.1.1. I am using custom board. With 5.Y.2 I can configure the custom board, but with 6.1.1 I'm not able to configure my board. How can I solve the problem?

Hello @prigh.1​ ,

With 6.1.1 you can start with an ST board as you did with workbench 5, and clone it with the board manager. Once your board is cloned you can customize it easily with the build in editor. Once done, you can start a new project with your own board and the Workbench will propose you the new possibilities offered by your modifications. Let us know what kind of modifications you want to do and the issue you are facing. It will help us to generate the right documentation.

Dear Cedric,

Thanks for your answer.

Yes, I have already tested the cloning procedure, as suggested by you. I can achieve some results, like defining the timer/pins generating the PWM signals. I can obtain this result by working on the controller's configuration or redefining the connector's pin/port configuration.

I did not find a solution for controlling the microcontroller's analogue input for reading the phase currents and OVC protection.

I am working with a sensorless motor with three shunt resistors, and the base microcontroller's configuration definied using MCWB 5.Y.2 is shown in the attached image.

MCWB 5.Y.2 allows me to configure the microcontroller in this way:

internal gain of the opamp

external gain and bias offset of the RC circuit for reading the current level (I know how to calculate all the needed gains ad offset)

inverted pin of the internal OPAMP for adding an external capacitor for filtering purposes

threshold limit of OVC

I did not find a solution using MCWB 6.1.1 to configure the analog input section as described above.

Do you have any suggestions or documentation for reaching these results?

Hello Paolo,

Could you tell me from which boards did you start with 5.Y.2 and attach your IOC file to this thread?

I will try to come back with a suitable solution.

Thank you @cedric H​  your reply.

I have the same question.

My own board with 1R or 3R is ok.

But I cannot create my board with 2 ICS.Can you tell me how to edit the file in board manager.

[cedric H]

Hello @CZhao.1​ ,

Unfortunately ICS is not yet supported by MCSDK 6.1.

It is planned to put it back in MCSDK 6.2 expected in July. For the time being, MCSDK 5.4.8 is still available and support ICS.

Hi @cedric H

Unfortunately 5.4.8 cannot work after cubemx is last version.

Help

You can use an older version of CubeMx, According to the release note of the MCSDK version 5.4.8 it seems that we can use at most the STM32CubeMX v6.4.0 version, can you try with this version ?

Hi. I just compared the replacement ConnectionParameters.json file uploaded by Cedric for the 6.1.1 release, and the stock ConnectionParameters.json in the 6.1.2 release. There are statements about "ThreeShunt_RawCurrents_SingleEnded_InternalGain" in Cedrics uploaded file which are not in the released 6.1.2 file, around lines 32/33. Is it possible your fix didn't make it to 6.1.12 release Cedric, please?
