    FX2LP descriptor for 2 UART on the same device

    SaTo_687856

      Hi !

       

      I need to implement 2 UARTs on my board with a single FX2LP device.

      One of them has to be bidirectional, the other one can be unidirectional (from device to host).

      I know that I have to use IADs (Interface Association Descriptor), but i did several attempts with no results.

       

      Can somebody tell me how to correctly define the USB descriptor (it would be useful to have an example...).

       

       

      Thank you !
