INTERNAL ZERO SCALE CALIBRATION
First I am doing the reset on AD7193. Then I do the following
i)write x80 to communcation register
ii)write x080010 to Mode register
iii)write x10 to communication register
iv)write x000110 to Configuration register
I have done this part successfully and also verified by reading these register contents.
I am having problem with calibration part
After doing the above four steps I again write to mode register x880010 (for internal zero scale calibration)
And then I wait for RDY' bit to go low as it indicates that the calibration is done. But RDY' bit never goes low.
I had posted this question 3 days back. Some one answered it and it got marked as correct answer, I tried to unmark it but it didn't go. That's why I am posting it again
