    Hi Tex,


    FYI that currently we don't have exact example design for 24-bit adc as Intel's board mostly in-built with 12-bit adc.

    May be can try to get the example design from the vendor of 24-bit adc.


    Thanks,

    Regards,

    Sheng

    Hi Tex,

    Max 10 ADC are line-in ADC. Usually Modular ADC Core IP is used for that. Check these two links http://gogofpga.blog.fc2.com/blog-entry-182.html and https://www.youtube.com/watch?v=0oO1RFa-4Xk&t=1s

    The SPI RTL design example can be found had been shared to you before. Can't find any VHDL one. Btw, the design store example design https://www.intel.com/content/www/us/en/design-example/715016/max-10-serial-peripheral-interface-master-an-485.html I had been tested on DE-10 Standard (Cyclone V) ADC since Max 10 ADC are line-in ADC. Check the attached design folder and STP waveform. The function as below:

    Control Register Write: CS high, WR high

    Transmit through MOSI: CS high, WR high, addr "10"

    Status Register Read: CS high, RD high, addr "01"

    Received (MISO) to data_bus: CS high, RD high, addr "11"

    Thanks,

    Best Regards,

    Sheng
