Example USB code for C6748

Roy Jackson
Intellectual 820 points

I am wanting to get started by creating a simple USB device such as a HID or DCD. I found the starterware USB CDC device http://processors.wiki.ti.com/index.php/StarterWare_USB#CDC_Device_Class

and I know the basics of USB, yet I am overwhelmed with the wiki information and all the starterware source files, and just need a way in.

I have also looked at EVML138 BSL example evmc6748_test_usb. This appears to be far more complex than I need (using OTG) and the documentation is rather thin and doesn't explain what's going on. Also, I haven't managed to build it yet, but if I can guess the right include files and libraries it might build soon

Does anyone know of a basic usb example project for CCS and C6748 that I can download and run?

 

Thanks

Roy

    Hi Roy Jackson,

    Would you please tell for what type of USB devices you are looking for USB device drivers?

    yeah, Sure, you can download the C6748_StarterWare_1_20_04_01 from http://processors.wiki.ti.com/index.php/StarterWare 

    once you install it, you will find the six USB examples. ( 3 - Device side examples and 3 - Host side examples)

    at path "..\ti\C6748_StarterWare_1_20_04_01\examples\lcdkC6748"

    Device side examples:

    1. usb_dev_bulk

    2. usb_dev_msc

    3. usb_dev_serial

    Host side examples:

    1. usb_host_kb

    2. usb_host_mouse

    3. usb_host_msc

    Using CCS, you can import these projects directly and run it on your target very easily. you can refer to the below TI WIKI link for importing projects. http://processors.wiki.ti.com/index.php/Importing_Projects_into_CCS

    If have any further questions, please revert.

     

    Regards,

    Shankari

    Thanks Shankari,

    That's exactly what I was looking for. I actually had already downloaded the starterware and seen the source files, but I didn't know how to use them. When I looked more thoroughly I discovered the project files for CCS. The usb-dev-serial example built and ran first time.

    Maybe the starterware wiki needs slightly more detailed instructions to help first-timers get started. E.g. your link to importing projects above.

    Thanks again,

    Roy
