ADS8507: Interacting with the ADS8507. How to get started?

Part Number: ADS8507

Hi,

I would like to use an ADC to collect and process signal data with a Linux mini-computer. The ADS8507 fulfills my needs, though I have no experience how to interact with the chip programmatically.

Any hints on how to get started will be highly appreciated,
Anjo

    Hello,

    The ADS8507 support both parallel and serial data transmission. which will you be using?

    As a parallel interfacing device, this means that each of the output measurements are transmitted through the D0 to D7 pins.

    These pins will each need to be connected to your processor. Note that two data transmissions will be needed to collect the full 16 bit measurement.

    As a serial transmitting device, all output data will be provided on one pin, SDATA, one bit per clock pulse provided.

    I suggest looking at the timing diagrams provided for the interface you will be using. Also, use oscilloscope probed on the digital communications lines to confirm the firmware is behaving as expected, and check timing. This will provide a visual check.

    Regards
