Synchronous Parallel Interface between ADS8422 (or similar) and TMS320F2807x MCU (or similar): Example C code or drivers available?

Other Parts Discussed in Thread: ADS8422

I'm interested in interfacing two ADS8422 ADCs and the TMS320F2807x microcontroller. I've been unable to find any example's related to interfacing TI microcontrollers with external ADCs (many examples for using the internal ADCs). I'd like to read 8 bits of data at a time using the microcontroller GPIOs. Can anyone give me some high level advice about that interface, particularly the following:

-best method to generate sampling interrupt.

-how to efficiently read results into memory (possible to use the DMA feature on the MCU?)

Any high level advice appreciated! Or relevant example C code!

    Hi Matt,
    I have some example codes for our SAR ADC interfacing with TMS320F2833x MCU, please send a email to me so that I can send the code to you for a reference. TI.com also has some general example codes for interrupt and DMA and so on which can be download.

    Regards

    Hi

    Can you send me this example code please? My email address is " apfelwn@hotmail.com "

    What is the common solution to interface a TI MCU with an external ADC that has parallel data interface?

    Thanks
