USB HID

Manasi Navare

I am trying to use the USB API library to implement the USB HID with single configuration but two interfaces, each interface having two endpoints. However looks like the USBHID APIs initialize only one interface by default. Is there a different set of APIs to implement USB HID for multiple interfaces?

Manasi,

We do not currently have APIs to configure HID for multiple interfaces.

Thanks Lela.

But is there any other work around to be able to configure HID for multiple interfaces?

Manasi,

You can configure the HID for multiple inferfaces, where the limiting factor will be the number of end points needed. We do not have the software drivers to do it within Tivaware, therefore, to do so you will have write your own software driver for it.

Hi Lela,

Thanks for your response. I have one more quick question, I am trying to send some apckets from the host to the device over OUT EndPOINt 1 of the type interrupt. I see the uSB packets going from the host to the device over the USB wire through the USB software analyzer but then I do not get the USB Interrupt on the device instead it goes into the Fault ISR while 1().

Is there any specific initialization needed to be able to use OUT Endpoint 1?
