so you implemented sw/airborne/peripherals/l3gd20_i2c.[ch] analog to the SPI implementation?
Can you share those files and the imu implementation? A bit hard to check anything without seeing the new code..
If you have it on github, a link to it is easiest...

Also which i2c bus are you using?

Cheers, Felix

my altimu10 makefile:  imu_altimu10.makefile

I'm just using i2c_submit fuction to read WHO_AM_I register of the chip.

If you can assist me, I'll be very glad.

Thanks for help!
