Hello,
I want to use the sensor with an OpenCM9 and libMaple.
I downloaded the libraires l3g-arduino and lsm303-arduino from your github.
I updated the code to make it work with libMaple.
I can initialise the magnetometer and the accelerometer but not the gyro.
I put trace logs in bool L3G::autoDetectAddress(void) but readReg(L3G_WHO_AM_I)
contains 0x00 after each try.
Any hints ?

Have you checked if the slave address is correct?
Hello.
I am sorry you are having trouble working with that gyro. Can you try manually initializing the gyro with a call that both specifies the device and SA0 state? For example, if you had the L3DG20, you could type init(L3GD20_DEVICE, L3G_SA0_HIGH).
-Jon
It’s fixed now. I found that the libMaple Wire.h was flawed.
Here are the different test with Arduino:

What are those values??? Did you move the IMU??
No. I have to calibrate it
