Champs,

AM5728 is required to drive 2 LCDs simultaneously and from the wiki article (http://processors.wiki.ti.com/index.php/Processor_SDK_RTOS_VPS_DRIVERS

    ok, looks the new post page somehow swallowed the second half of my message - here is the rest: from browsing the doxygen and VPS sources I can clearly see that VPS library supports driving any of the 3 LCDs available on the SoC but it is not quite clear how to create two LCDs to run in parallel. Any guidance will be greatly appreciated!

    thanks
    Michael

    Michael,

    Our AM57x GP or IDK EVM can only connect to one LCD at a time, so the provided examples are based on one LCD display.

    To support 2 LCD in parallel, is this some customized board? There needs many changes for these customized platform:
    1) pdk_am57xx_1_0_5\packages\ti\drv\vps\src\boards\src\bsp_board.c this is the top level board file, user needs to add their own board definition

    2)pdk_am57xx_1_0_5\packages\ti\drv\vps\src\devices\lcdCtrl\src\bspdrv_lcdCtrlApi.c here they need to add their own LCD driver

    3)pdk_am57xx_1_0_5\packages\ti\drv\vps\vps_component.mk. If they use our make process, this file need updated to build the example for their board.

    Regards, Eric

    Eric,

    From the initialization perspective - Browsing through the display example it looks like 

    numInst used in pdk_am57xx_1_0_5\packages\ti\drv\vps\src\vpsdrv\dispdrv\src\vpsdrv_dispAPI.c actually defines number of display drivers in the system, so for 2 LCDs it should be 2 . Is this correct understanding?

    thanks,

    Michael
