General HID class device with Jungo

Other Parts Discussed in Thread: OMAP-L137

Hi

I'm working with OMAP-L137 EVM and I want to adapt the HID keyboard example code to general HID. Unfortunately, this is not very easy since the Jungo documentation is very poor and the HID keyboard example is by far not self explanatory (nor is the Jungo API). Could you please give me some hints on how and where to begin (to adapt the code)?

By the way (I'm quite new to USB): with the HID keyboard example I'm limited to USB low speed - is it true that I can go for full speed with a general HID device, i.e. transfer 1023 bytes/ms?

Thank you very much for your help and advices.

Andreas

    You would have to assemble the related USB descriptors that specify the capabalities of your device.  Beyond that the HID Keyboard/Mouse example can be used as reference to construct your own apps.  If you are new to USB I would suggest that you either read about USB from say a book  or from the net. 

    What are your USB application needs from functionality and throughput perspective ?

    You can advertise your device as Full/High speed device.  Low speed device is not support.

    regards
