Missing library "TrajCtrl.h" when creating project on kit STEVAL-ETH001V1

[phamtutailtvm]

I bought the STEVAL-ETH001V1 kit on digikey. I also downloaded the firmware for the servo drive. However, when I build this project using keil c, the "TrajCtrl.h" library is missing and this library is not provided in the firmware.
I would like to ask where I can find this library or can someone help me?

Hello @phamtutailtvm,

Loading project on IAR, PositionDemo.c file, that uses TrajCtrl.h file, is not part of the project. Could you try without it?

Why don't you provide that file in the firmware? I use Keil C to run and debug for my project. So i need that file to continue my project. 
If possible, can you provide me that file?
