I am currently successfully using igepv2 with linux framebuffer directfb driving a standard hdmi display monitor that plugs into a wall. I would like to purchase a small (4" to 10") display that can run off the hdmi cable (or use its own battery). Does anyone have any suggestions?

I see Lilliputuk.com has a 5" ($244) and 7" ($188) hdmi displays built for cameras and gechic on-lap has a 10" ($294) and 13" ($200) hdmi display for cameras and Windows. I am not sure if these will work with linux framebuffer directfb the same as a "plug in the wall" display. Has anyone tried these "camera" displays on igepv2?

If there is no suitable hdmi portable display that can "plug and play", does anyone have a suggestion of what I could hack together. I do not have any free gpio's without resetting defaults.... I see ISEE has a 7.0” SEIKO RGB 24 bits TFT Display as part of a kit, but I could not find instructions on how to wire that into igepv2 and what changes are needed to Linux to make it work with directfb.

Any suggestions are appreciated!

Peter

    Hi peter,

    You cannot power a display using the own HDMI cable, because HDMI 5V line has a low power profile. A quick search give me this result: http://www.adafruit.com/products/1666

    You can power up this display with 2 cell LiPo Ion battery

    I see ISEE has a 7.0” SEIKO RGB 24 bits TFT Display as part of a kit, but I could not find instructions on how to wire that into igepv2 and what changes are needed to Linux to make it work with directfb.

    Look the IGEPv2 Expansion board SCH, you will find how IGEP DPI bus is connected to Seiko display. For use directfb with Seiko display, you only need to configure igep.ini: http://labs.isee.biz/index.php/What_can_I_do_with_IGEP_BERLIN#How_to_use_TFT_and_Touchscreen
