Good morning, I have bought several NAU780X boards (24-bit ADC for Weight Scales and Precision), which work fine for me on an Arduino Mega, but since the project requires more power we have an Arduino DUE, but the library does not work for me: SparkFun_Qwiic_Scale_NAU7802_Arduino_Library .h
This is very important for us since we changed the ADC HX711 cards for these NAU780X, this is a prototype machine that we must deliver for evaluation.
Can you tell me where I can find a library that works with the Arduino Due or indicate what I must change in the library to make it work for me?
The Due has some funky stuff with its i2c if I remember correctly; I believe it needs to use TwoWire instead of the regular Wire (adjust the code to match; ‘sda1’ or similar)
If that doesn’t work you can also try disabling the pull-up resistors if they are still in-place…any change?
I’m looking for someone I can hire to figure this out. I have two load cells with NAU7802 and a multiplexer to be able to read each cell at the time required, the cells are read individually, not at the same time.
Hello, I am trying to get the NAU7802 scale board connected to a strain gauge to plug into an Arduino MEGA2560. I am connecting four wires from GND, 3V3, SDA and SCL solder points on the scale board to the Arduino and attempting to use the example1_basicreadings, and it is not working. Depending where I put the clock and data pins on the Arduino it will display something like this:
11:00:45.151 → Reading: -565371
Where is the correct place to put the data and clock pins? I have seen other posts mentioning using jumper wires to different points on the Arduino. Is that necessary? Do I need to modify the example Arduino code at all?
Thank you for any assistance you can provide.
