    Hi, I'm working with the sh7727-20 kit, and the display doesn't seem to be working. The LCD is getting power, however windows CE will not load a display. I can't test the display using video-open, since the display quickstart guide says that the LoLo doesn't support the LCD-3.5-QVGA-20 display mode that this lcd uses, and I haven't found any updated information on this. All connections seem to be good, any suggestions?

    Thanks,
    Pete

    Pete,
    Have you made sure you are using the correct video mode in the display driver registry file?

    If using the LoCE_SH7727-20_beta_002 BSP with the LoCE_SH7727_beta_002 display driver, you must set the following Platform Builder enviroment variable to 1:

    LCD_QVGA_16BPP_LQ035Q7DB02

    If you take a look at the .reg file for this display driver (SH7727_LCD.reg), you will see what this variable specifically does.

    Hopefully this helps,
    Mike A.
