Hey STM community,

I have a G431RB & IHM16M1 however whenever i try to run the motor pilot, i cant seem to connect to the board. I  have made sure all the necessary link drivers are installed, i have made the baudrate  115200, 8bit all to match up with the software but i consistently get no connection. My cube ide, motor workbench and motor pilot are all up to date and i have the associated packages( the G4 library v1.61) installed in cube-mx.

Thanks

Hello @Gath0004,

he easiest way to connect the motor pilot to the board is to use the Discover Board feature.

By default, a baud rate of 1843200 is used.
Select the COM port to be used (it is not COM3)
