I have a motor control application generated with MCWorkbench and am successfully using it on my custom board. I added many custom features to the application such as CAN Bus, absolute encoder and my own position control to suit our application. TI a...

I designed my own motor controller board and it works fine. For the next revision, I am looking into reducing parts count and simplifying schematics a bit. In the sense control area, I have tested the option of using the internal gain for the OpAmps ...

I designed my own PCB largely based on the EVALSTSPIN32G4, mine being a four layer board with components on both sides for compactness.I generated code using MC Workbench 5.Y.4 with hall sensors. I implemented my own absolute encoder via SPI, and add...

Going over the documentation for the EVSPIN32G4, this is the schematics for current sensing:But starting a project in Motor Control Workbench for this board, seems to have different values for the same schematics:Am I missing something? Why the discr...

Ok, for now, I just manually created #ifdef declarations for each motor profile inside:pmsm_motor_parameters.hdrive_parameters.h. The caveat is that if code is updated using MC Workbench, these files would be overwritten since they have no "USER COD...

I apologize. I have no updates on this. I went the normal route of using MC Workbench and running my board that way. I did not pursue the Unit Test of the gates on their own. You could try the latest Mc Workbench update 6.1 to see if that helps with ...

You are right, timing of measure is critical. Maybe that is why in ST implementation they still use the input from the third shunt. I will look into it and dig into the code. Thank you again. In the meantime, if anyone has implemented it, I welcome c...

@KnarfB thank you. That's my question: I want to calculate the 3rd value based on the other two. Do you have any implementation ideas?

@Peter BENSCH after spending more time on the solution, I am planning to change the power topology as follows:I will power all peripherals to be power by a 5V 300mA external buck converter, e.g. L7983PU50R. I was able to source all peripherals Vin 5...
