here is our code. We're not sure why our accelerometer outputs zeros. Is it initialized right? Is there a better way to get the axis values?

We're calling it from RobotTemplate, where the accelerometer is initialized as:adxl = new ADXL345_I2C(1, ADXL345_I2C.DataFormat_Range.k2G);



We're wired to the I2C on the sidecar using a pair of double-female wires (0V,SCL,SDA,5V) so we're pretty sure we don't have wiring issues.
