Hello, I am Sky.

Currently, I use the USB CDC ACM device class driver to communicate with my application, and it works pretty well.

But, it is a burdensome to install new driver at first time.

Therefore, I am looking for an alternative way without installing a new driver, and I have found that HID class is the appropriate solution.

When I refer to examples in "TivaWare_C_Series-2.1.3.156" folder, I found few examples for game pad, keyboard, and mouse.

However, I would like to define my own message type with 256 bytes message.

In my opinion, a kind of the tutorial of the usb bulk example is perfect,

because it supports both sides: host-side codes (usb_bulk_example) and mcu-side codes (usb_dev_bulk).

If you have an appropriate tutorial for a HID communication,

please let me know a location of materials.

Thanks,

Best Regards,

Sky.

Hi Sky,
Have you checked out the usb_dev_keyboard and usb_host_keyboard examples under <TivaWare_installation>/examples/boards/ek_tm4c1294xl. These two examples use USB HID class.

Thanks Charles Tsai,

I am sorry for my ambiguous expressions.

I wrote down the terminology "host-side" which means a windows application like the "TivaWare_C_Series-2.1.3.156/tools/usb_bulk_example", which is written in the Visual studio Environment.

I think that both source codes you recommended are "mcu-side" codes.

Thanks,

Kind Regards,

Sky.

Hi Sky,
You can find window side usb bulk application in TivaWare under <TivaWare_Installation>/tools/usb_bulk_example.
