ADXL372 with Arduino Due

Hi there,

I’m using a grove 3D accelerometer (200g) with a base shield on arduino Uno. It works fine but the sampling frequency is limited to 1.8kHz, because reading the accelerometer and writing to the serial port is time consuming for the Uno. Then, I bought an Arduino Due, and it seems that the adxl372.h library doesn’t work. I can’t “begin” and obtain the device ID in the setup part of the code.
The shield is on 3.3V and the card works fine with other program, the wire library is well documented and seems OK for the Due. An idea to run the ADXL372 library on DUE?

Thanks!
Etienne

The only difference is 5V level communication on Arduino UNO, but 3.3V level communication on Arduino DUO.
