ADS7809 interfacing with MSP430FG4618

Other Parts Discussed in Thread: MSP430FG4618, ADS7809, ADS8509

Does anyone have any experience with ADS7809 A/D converter with MSP430? I’m trying to use MSP430FG4618 to control ADS7809 (external clock, internal reference), but has no success. Can someone provide a hint or code? Here’s the datasheet.

P.S. I do have a level shifter in between MSP430 and ADS7809.

 

Thank you for your help.

    First, teh ADS7809 is flagged NRND, which means not recommended for new design. Which is obviously what you're doing (a new design).
    You should go for the ADS8509 instead.

    Anyway, teh transfer protocol of the 7808 seems to be SPI, either master or slave. Slave mdoe is easier to handle with MSP, but requires polling of data.
    It is, however, mostly straight away and there are several threads in this forum which deal with SPI transfers of different kind.

    There may be even threads which directly address the 7809. At least I dimply remember that interfacing external 16bit A/Ds was topic of one of the threads I responded to in the last year.

    May I point you to the search funciton (it is in teh uppe rright area of the browser window. You can identify it by the 'Search Community' tag in the search topic input window.
