ncm:Out in itf

[momoxuelin]

Hi,I'm a newbie，I want to use ncm in my project, but I don't know why there are two Out page in itf?

Or is there any documentation to help me understand the source code?

The comment says "Received NTB status and double buffer" which is really all you need to know. You should look at the USBD_NCM_Exported_Functions section of functions, which is the public API of the class. For a demonstration project on how NCM can be integrated and used, see IPoverUSB project. If you want to understand the internal operation of the source code, you can read the comments in the file, and read the USB NCM class specification.
