How to calculate the current measurement parameters for the board designer tool

MotorHobbyist

Hello everyone!

Based on the shot I provided, there are some parameters that I don't know exactly how they are calculated.

What are the Polarization Offset and Offset network attenuation parameters and how could I calculate them? Is there any user guide for that?

It's very useful when designing a custom board

Thank you all

Hello @MotorHobbyist,

You can use the embedded tool available on MCSDK5.4.8 Version available here.
Loading "B-G431B-ESC1 electronic speed control" example and clicking on "Analog Input and Protection" and "Calculate" on "Sensing OPAMP" box, a graphical interface pops up that provides amplification chain parameters computation according to resistor values.
