    Is it possible that you are seeking an LCD?      (unsure as we may have "missed" one (or more) of your duplicative posts - included in today's barrage...)

    You have started several threads requesting information about a 7 inch LCD display. I am going to link the other threads to this one and try to put answers here.

    TI does not make LCD displays. We do make the TM4C1294 microcontroller and the EK-TM4C1294XL Launchpad. The TM4C129 has a parallel interface (EPI), an SPI interface (SSI) and an I2C interface. All three are commonly used to interface to displays. A 7-inch 800 x 480 display can require a lot of data transfer. In general the parallel interface is fastest, the SPI second and I2C is third. However, the parallel interface requires the most connections (wires) and the I2C the least. Don't get a display that requires VGA or HDMI input as those interfaces are not directly supported on the TM4C1294. The signals from the TM4C1294 are 3.3V so you are better finding a display that has 3.3V signals, although most TM4C1294 pins are 5V tolerant.

    We do not have a canned example using a 7-inch display. We do have examples that use a Kentec 3.5-inch display. The graphics library that comes with TivaWare can be customized to different size displays. Do some WEB browsing and read about the different peripherals I mentioned in the datasheet. Also, download Code Composer Studio and the TivaWare library if you have not already, and play with some examples. Let me know what you choose.
