Question
I have a project about measurement weight and inertia. I have used ad7730 3
items in the project. I couldnt calibrate them. I read PDF file many times. I
check it. Can you send me short pseudo code for calibrate it.
Answer
First check that you really have established communication with the AD7730 by
attempting to read the power on default values from the status register (CX
Hex) and the gain register (59AEE7 Hex). If you don't read back the default
values you need to review your digital interface and try to correctly establish
communication with the AD7730. Then you can start looking at how to calibrate.
Pseudo code for calibration is included in table XIX on page 37 of the
datasheet.
