Hi,

Thanks for the help with setup of the board. I'm now trying to use the EVM to read a load cell output to a microcontroller. Mine is an arduino uno. I made the connection as you explained, but I'm having trouble finding code that can support simple reading of the ADC. I can't find sample code with addresses etc. If you know of such, that would be very helpful. 

Thanks

    Hi Eitan,

    There should be some base I2C Arduino code examples that you can use from within the community.  Below is some code that perhaps can get you started:

    #include <Wire.h>

Wire.begin();                                   // join i2c bus (address optional for master)
  Wire.beginTransmission(device);                 // start communcation with device (48...4B)
  Wire.write(0B00000001);
  Wire.write(highByte(setupdevice));              // Set I2C address to device (48...4B)
  Wire.write(lowByte(setupdevice));
  Wire.endTransmission();

  Wire.beginTransmission(device);                /// start communcation with device (48...4B)
  Wire.write(0B00000000);
  Wire.endTransmission();

  Wire.requestFrom(device, 2);                  // request 2 bytes from slave device #2
   byte a = Wire.read();
   byte b = Wire.read();
   word code=(a*256)+b;

    Best regards,
