EK-TM4C1294XL: interface Tiva with DLP6500

Part Number: EK-TM4C1294XL

Hello team,

at one of my customers, they are implementing the Tiva with a DLP6500. Namely they've testing the ek-tm4c1294xl and DLP6500 evaluation boards. With help of “TivaWare™ USB Library” software and one of the evaluation board example – usb-host-keyboard- they succeeded to connect with and disconnect from DLP device, but when they try to send a data, they did not get a response.

I’d like to know how to configure the USB host library in a right way in order to communication with DLP6500 evaluation board.

Any suggestion is much appreciated.

Thank you and best regards,

Adrian

    Hello Adrian,

    I looked through the documentation for the DLP6500 and from what I can tell it enumerates a HID device and uses USB 2.0 so our host library should be able to support it. That said, I am not familiar with that device and the commands required to communicate with it and from what you are describing to me it sounds like the command is just not being recognized. That would be an application specific problem to the DLP6500 at that point, and I would suggest reaching out to the DLP team as we have never interfaced a Tiva device to a DLP EVM before and have zero knowledge on what the setup would require - including if there are any specific USB host configurations required.

    If you find out details about needing a specific configuration but don't know what API's to use in order to configure the USB library correctly, then please reach out to us again and we can definitely offer support for that aspect.

    Hello Ralph,

    I'was in contact with Adrian regarding DLP6500 control via Tiva usb library. I'd like to specify the problem.

    DLP team said DLP6500 support standard HID interface.

    Tiva usb library has keyboard, mouse and mass storage devices examples.

    So my question is how to configure the "TivaWare™ USB Library" to work with "standard HID interface" device?

    Do you have any examples?

    Thank you,

    Maxim
