ADS7830: ADS7830 I2C reading information

user4979899
Expert 3080 points

Part Number: ADS7830

Hi Sir,

We use ADS7830IPWR as HW monitor to monitor Baseboard power rail status.
And we access this chip via I2C and get below byte back:
Could you please guide us how decode below info? and can we set threshold on it?

I also attached the schematic as below for reference,

Thanks

    Hello,
    Another method to debug your ADC is by using an oscilloscope. Using an oscilloscope shot you can visually see what is happening at the digital communications lines. You can then compare what you expected to see based on your code and what is happening in reality.
    I would suggest connecting to the digital communications lines, and making sure that what your code is outputting is correct.
    This will also help confirm your timing.

    Also, use known DC values at your inputs. This way you know what to expect when you are reading your output. You can also use different DC inputs at each channel to confirm that the ADC is reading the correct input. i.e. Ch0 = 1V, Ch1 = 2V and so on.
