USB Virtual comport

majid said:

The example code is working well (usb_div_serial.c) but when I want to add USB part to my code there are some errors.

Compare the project properties of the working example program usb_dev_serial to your CCS project.

See at CCS->Properties->Build->ARM Linker->File Search Path.

Hi kel,

Thanks for your prompt reply,

As you can see in attached files I added search path to the project. and there is not error in the header,

when I am adding those USB header line, an error happens in other line which that line is a comment.

thanks

Hello Majid

Did you add #include "usblib/usbcdc.h"

Hi Amit,

Yes I added, as it shown in the attached files.

The search path is correct and there is not any error in the header but why there is an error on a line in the code that i did not have it before adding USB header?

Thanks

Hello Majid,

You have included "usblib/device/usbdcdc.h" as shown in the first code post. What I was referring to is "usblib/usbcdc.h"

Hi Amit,

Yes I did it, But there is not file  in "usblib" directory with name of usbdcdc.h and it is in this folder  "usblib/device/"

thanks

Hello Majid,

Please have a look at the snapshot of the TivaWare installation

Amit

Dear Amit,

I really appreciate your help.

Attached shows that I install Tiva ware package. Does it works If I copy those file to the “usblib” directory?

Note that “usb_div_serial” example use the same directory that I used and it works fine.

Thanks

Hello Majid,

You can check the directory where TivaWare is installed for the file I showed earlier. Or even simpler add it and compile it!!!

Regards

Amit
