EK-TM4C123GXL: TM4C123GX add more keyboard descriptors

user5851352

HI sir,

At present, TM4C123GX has been simulated as a keyboard through USBlib, but there are a few descriptors missing from the real Keyboard descriptor.

I want to add these missing items to usbdhidkeyb.c in Usblib. Could you give me more suggestion? Thank you very much.

The link is as follows (Logitech Gaming Keyboard descriptor):

I'm not an expert on the Keyboard descriptorx. You will need to check what are the differences between the Logitech Keyboard descriptors (e.g. device, configuration, interface, HID and etc) and what is currently defined in the usbdhidkeyb.c. I think the biggest difference will be the report descriptor that you will need to modify in the g_pui8KeybReportDescriptor in the usbdhidkeyb.c file according to your Logitech keyboard description.

Below article may be helpful too.
