Hi Chuhua,

1. In CW 10.7, we can create library with wizard, just select "library" for project type.

2. after creating the lib project, write your functions in source code and also declare it in header file (.h)

3. copy the generated .lib and .h to user project folder.

4. add the lib path to user project "properties", "settings", "DSC Linker", "input", "Additional Libraries"

Please follow above steps and see how it works.

Have a great day,
Jennie Zhang

Not a video, but something to read: A Library with ARM gcc and Eclipse | MCU on Eclipse

Same principle applies for DSC too.

I hope this helps,
