Other Parts Discussed in Thread: EK-TM4C1294XL, EK-TM4C123GXL

Hello,

I am trying to implement an application to download the serial port data in pendrive using TIVA c series launchpad USB access. First I want to access pendrive using TIVA Launchpad. After googling the web pages, I am trying to download the usb_host_msc example into my tiva c series launchpad. I have made the hardware corrections as in the following link https://e2e.ti.com/support/microcontrollers/tiva_arm/f/908/t/390526.

How can I see the output for usb_host_msc example. Anyone can help as soon as possible. Please let me know is there any other corrections to be done.

    Hello Keerthana,

    Which Launchpad are you planning to use?

    The EK-TM4C1294XL LaunchPad does not require any hardware changes and the example "./examples/boards/ek-tm4c1294xl/usb_host_msc" can be used without any changes to the hardware or software.

    The EK-TM4C123GXL LaunchPad requires hardware changes. Also the example "./examples/boards/dk-tm4c123g/usb_host_msc" must be modified to work with "EK-TM4C123GXL" board.

    Thanks,
    Sai

    Hello sai,

    Thank you. I am going to use  EK-TM4C123GXL launchpad. Please let me know the corrections in usb_host_msc example. What is the alternate for LCD display library in usb_host_msc.

    Hello Keerthana,

    The forum post that you linked in your first post, already has the necessary connections.

    Since EK-TM4C123GXL does not have an LCD, you can use UART0 to send and receive data. This way you can interact with the board using a terminal window. TivaWare has a utility, called "cmdline" (in the folder "./utils") that makes it easy to send commands to the board. The example "./examples/boards/ek-tm4c1294xl/usb_host_msc" can be used as a reference.

    Thanks,
    Sai
