Trouble reading load cell into Arudino Due using 16-bit ADC
Sorry to hear you have a problem, but I suspect more information is required for anyone to have a reasonable chance of diagnosis. In particular, describing your hardware setup in more detail, as well as attaching a software listing.
As a first stab in the dark, I note you say the load cell power is 24Vdc, which leads me to wonder what the output voltage going to the ADC is.
You don't describe the ADC, but most chip ADCs expect voltages to be quite low ... typically 1-3V max. Obviously, your system may include intermediate circuitry to deal with this situation.
Is there any chance the voltage going to the ADC is causing it to hang up?
It is common for a simple program to start an ADC conversion, then wait for the ADC to report that a new conversion result is available. If the ADC 'hangs' and fails to indicate the new conversion for some reason, a simple program may wait forever.
Good luck. Dave
