    Hi liu billy,

    We don't have ADS1251 example code to share

    However, please note that the ADS1251 does not have any registers to program and has a read-only interface. You just need to set an interrupt in your MCU that waits for DRDY to transition high to low, then send 24 SCLKs to read out the data. It really is quite simple

    Hi liu billy,

    Additionally, I will point out that the ADS1251 is an older ADC, and we have many newer devices that might work better for the customer. We also have example code for many of these newer devices

    If you can tell us more about what signals the user is trying to measure, what data rates and resolutions they require, how many channels, etc., we can provide a short list of new devices to choose

    For example, the 24-bit ADS127L11 is a much more recently-released delta-sigma ADC that offers excellent AC and DC performance, data rates up to 1 MSPS, multiple filter options, and low power. And we have example code for this device + an evaluation board.

    Let me know

    -Bryan
