    Hi house,
    please im still stucked on this project, trying to make an electronic billboard that will read in its data from a flashdrive instead of connecting it to a PC via the COM PORT, if it is possible, how do i go about it?

    2) If the above is not possible , how do i use the USB PORT instead of the COM PORT to stream in data.

    Thanks
    Manuel

    If it's going to use a flash drive, then USB will have to be the choice. Does the display have a processor in it that can use the USB interface, import files, and display them?

    Reading USB can be expensive, there's a hack to allow simple GPIO to read an SD card in SPI mode. It just so happens that an SD card can fit in a floppy disk connector. Just hook up the right pins and something as lowly as an arduino can play with them. (atmega168)

    Tada!
