omap4460 15 inch touch panel

Hello Ti

omap4460, Android:ICS

I need to port 15 inch touch panel  with DSS

Display controller (DISPC)
• Remote Frame Buffer Interface (RFBI)
• Display Serial Interface (DSI)
• NTSC/PAL video encoder (VENC)

The first goal is enabling the LCD
Except board-44xx-tablet-panel.c I need to revise. Are there any files I need to revise?

Thank you.

  • Hi Bernie,

    That is correct, you start from the panel file but mind that some driver specifics may require you to modify the interface drivers.

  • Hi Ti

    I would port step by step, but we need Ti's support...


    I have revised something below, what else sections we need to ? Thank you.

    static struct omap_dss_device tablet_lcd_device

    {

    ...

    .panel = {
            .timings = {
                .x_res        = 1024,
                .y_res        = 768,
                .pixel_clock    = 65000,
                .hfp        = 24,
                .hsw        = 136,
                .hbp        = 160,
                .vfp        = 3,
                .vsw        = 6,
                .vbp        = 29,
            },
        },

     ....

    }

     

  • Hi Bernie, 

    I have a couple of questions before I start guiding you through the process.

    Have you achieved communication with the display ? Which interface did you intend to use?

  • Hi Boyko

    Thanks your reply.

    I have solved this issue, but I get confuse now. We will discuss with you and post patch tomorrow.

    BestRegards

    Bernie

  • Hi Boyko

    I post part of patch.


    What is confusing  me is  TRM tell me LVDS  is consisted of DSI interface, but I revised the code with DVI interface it is can be work. What is the deference between them? Thank you.
