STEVAL-IHP005V1(STM32F103x, ST7540) inquiry

Hello, I am a student studying stm32.

I bought that module. I want to modify the source code in CUBEIDE.

A part of the PLM stack folder is in the form of an object file.

Can I get the file in c code??

I don't know the exact email address, so I'm posting it to the community thank you​.
