Please assist me to interface  WVGA/LCD EI3 Extender  Board Rev 1.0  on EPPI 2 (i.e  connector P3A ) of ADSP-BF609 EZ-Board Rev 1.0. I have been trying to do this past 3 weeks with no results. I am not able to identify any problems and also possible solutions. I have already interfaced LCD module on EPPI 0 (i.e connector P1A) using example code "colorbar"  provided by Analog Devices website.

I appreciate the support from Analog Devices till this date but none has solved my problem. I would really appreciate if any one of you would put me on the right track to interface LCD module on EPPI2.

 

i made two changes in the following files of colorbar.c example code

 

  In colorbar.c file

if(adi_nl8048hl11_SetPPIDevice(hVideoOutDriver,

                                        PPI_DEV_NUMBER) != ADI_NL8048HL11_SUCCESS)// PPI_DEV_NUMBER=2 for EPPI2

        {

            REPORT_ERROR("Failed to set the PPI device number \n");

            return;

        }

In SoftConfig_BF609.c file

 

in SwitchConfig1 for port A i have passed  { 0x12u, 0x4Bu } values but still LCD module not working on EPPI2 (P3A) connector of ADSP-BF609 KIT
