Hi,
I saw several questions in various forums about using the INA125 for an amplifier interface between a load cell and an Arduino to get faster response than with the HX711.
The problem was that using the 5V single supply from the Arduinio to the INA125 would only achieve positive load data.
You can solve this by using the excitation from the HX711 and tie the psuedoground (INA125 -PIN5) to the -E excitation of the HX711.
This will give Tension and compression data output from the load cell.
The INA125 pins: 16, 15, 14, 13, & 4 would not be attached.
To get milli-sec data you cannot use an LCD as it slows down the Arduino's response time.
This basically fixes two problems I have seen in forums - slow speed of the HX711 and single supply voltage (5V) Tension and compression from the load cell using an Arduino.
I used the INA125UA
Was going to post an Eagle Cad diagram, but there is no means to do so.
