How do I access EMIF between ADC and OMAP-L137/C6747 ?

Hi everyone,

    I don't know how to access EMIF between ADC and OMAP-L137/C6747. The followings are my related questions.

    Environment : [AD Converter]---------------(16 pins)----------------[OMAPL137/C6747] 

                               ====> I use the Spectrum Digital's OMAPL137. And I'll connect ADC and DSP board by wire. And slot the wire in the port P13 on OMAPL137.

   (1) How do I access the data sent from ADC to my board ? Does it use the asynchronous devices to access (like NOR,NAND flash and SRAM) or not ?

   (2) What are the setting and configuration manners ?

   (3) Are there any example codes to demo these ?

Sincerely,

Yang

    Yang,

      You're best bet is to connect the ADC to the Universal Parallel Port (UPP) and retrieve data from reading the UPP registers.  The settings will depend on the configuration of the ADC, and the hardware wires you have connected to the DSP.

      I'm not aware of any example code for a parallel ADC.

    Hi Drew,

        If I use the peripheral of uPP, what will EMIFA do ? I don't know these peripherals very well.

        And where is the corresponding port of uPP on OMAPL137?

        Any reply will be appreciated. Thanks.

    Sincerely,

    Yang
