I've been trying to interface ADC CS5532 to P89V51RD2. I have reset the ADC, written configuration bits to the configuration registers. I am trying to use the single conversion mode.
However, while reading, I either get a sequence of 24 0s or 24 1s. One thing that does happen is that the overflow bit is set whenever the input is above the reference voltage. This has got me confused very much now. If the ADC is reading the data and is acknowledging the overflow, why won't it give the the value? What seems to be the problem?
Thanks in advance.
I also am not understanding the role of the A0 and A1 latch pins. I'll be trying meanwhile.
