Other Parts Discussed in Thread: OMAPL138

Hi,

     We are working in OMAPL138 Processor which have inbuilt LCD controller.In LIDD mode,it supports hd44780,6800,8080 family interfaces.But here we are using winstar 128x64(MODULE NO.:WG12864F-TMI-V#Y) LCD.

Whether is there any possibilities to directly interface inbuilt OMAPL138 LCD controller with our 128x64 LCD  display.

If that is not possible please let me know some work-arounds or suggestion, coz changing LCD display a this stage is not possible.

Expecting your valuable suggestions  ASAP.

Regards,

Thavamani

    Hello Thavamani,

    The WG12864F appears to be a 8-bit interface. Our LIDD is 16-bit. I believe what you are asking is how to interface the two. Am I right?

    If so, what you can look into is to pad every byte of data (in memory) with one bye of dummy data. Basically, you are still outputing 16bit data, but only the valid byte goes to your display.

    Please let me know if I am answering the right question.

    regards,

    Paul
