Pervasive Displays

Li Chen92
Expert 3040 points

Hi TI expert

I have the Tiva C Series launchpad evaluation kit. It has been many years since I have done MCU level development. I have an E2B98FS081 Pervasive e-ink desplay along with the EPD extension kit to interface with the development board.
Usually datasheets of displays come with pulse and command diagrams that outline specifications to initialise the display, send commands and otherwise manipulate what is being displayed; however, I do not see such things with this display. You do have smaller EPD displays that you have associated projects for on the your launchpad development boards, so I thought you might be able to direct me to resources on how to get started with this particular display? Any help, guidance or sample development project files would be highly appreciated.

Thank you in advance.

Thomas

    Hello Li,

    Unfortunately we don't have a lot to offer here. I was trying to see what sort of e-ink support we may have given before but I came up empty. It's not a display type we have put any resources around.

    From what I see, that particular display is controlled via SPI, so I would expect the commands needed are simply SPI protocol related which means you won't have as much issues with timing diagrams beyond sending commands quick enough to get your desired refresh rate for the display.

    As far as getting stated with the display, I would say that either you will need to acquire the documentation or find existing code projects online. Maybe someone else put together a library for another Arm MCU that you can try and leverage. You can also look to see how we handled the TFT display that we support for TM4C as well, the examples for the BoosterPack use the SPI interface to control the LCD. This will also show you how to leverage our Graphics Library for this application which will be useful for you I think.

    I know this isn't much for you to work with but unfortunately we just never put together collateral for an e-ink display before.

    Hi Ralph

    Can you please provide the link to the TM4C series SPI Graphics Library resources you mentioned? I'm sure it'll come in handy down the track.

    Best regards,

    Thomas

    Hello Thomas,

    They are part of our TivaWare SDK: https://www.ti.com/tool/SW-TM4C

    Look in the examples/boards golder for the 'Kentec-S1' example folders as that BoosterPack uses SPI for communication to the LCD. The drivers folder for the examples will have the SPI driver files.

    Best Regards,

    Ralph
