ADS8634: Request for spi dev test application

Part Number: ADS8634

Hi,

Please help me in reading 4 ADC channels raw data through spi register with test application. I have added spi dev driver for the same .

Regards,

Deeksha

  • Hi Deeksha,

    Can you please capture and share few timing plots for SCLK,/CS,DIN and DOUT with an oscilloscope according to the following procedure and configurations?

    1. Apply a precision DC voltage to one of four input channels or short it to the ground.

    2. Use Manual Mode to select the specific channel which has applied a certain input signal in step 1. See Register Write format in Figure 89 and Manual Mode Register on page 40 in the ADS8634 datasheet.

    3. Print the timing plot for frame 1 (register write), frame 2 and frame 3 which includes the conversion data for the specified channel.

    Your schematic will be very helpful to address the issue. Thanks.

    Best regards,

    Dale

  • Hi ,

    Is there any driver available for this module. Could you tell me how can I read

    output data from ADC with spi interface.

    Regards,

    Deeksha

  • Hi Deeksha,

    There is no example code for this mature device. As recommended in my previous post, please refer to the steps above. Note that the /CS signal is used to initiate a conversion and see the timing in Figure 1. All information are included in the datasheet, please check it here ADS8634 datasheet.

    Best regards,
