I am evaluation the AD7190 for a weight scale application. Everything works nice, except the calibration. No matter what I do, the calibration does not work.
- I am resetting -> works
- I am setting channel, gain and other parameters in mode and config register
- I am setting mode to Internal Zeroscale or Internal Fullscale
- The ready-signal goes high in the middle of the register setting, but never returns low. The offset register is never changed, neither the calibration register.
Is there anything, I forget to complete?
I appreciate any help, I already lost days on that...
