hi all,
my 9 dog imu on arduino 1 r3 doesn't work.
I followed your direction in setting ll components, I did it more time on different IDE versions.
i tryed on 1,5,8 and 1.6.0, both compile and load correctly, but program hangs in the first begin of any application.
i'm using only your sketches but I can't get any result in any test.
if I disconnect the IMU board I got the correct message 'no LSM303 detected ... Check your wiring!' So the wiring seems to be ok, I checked it more and more time.
any suggestion are welcome!
thank you

Post a photo of your hardware and connections and we'll take a look.

Re: imu 9 dof do not work
here a view of my prototype. I used a flat cable to wire boards.
consider that hw works fine with other sketches, but it's my first experience with i2c
thank you

Re: imu 9 dof do not work
I can't see the points of connection for the SDA and SCL wires to be sure, but it looks like you have them soldered into the holes for a pin-13 LED.

mike,
attached here a detail of arduino 1 board solder side, as you can see the 2 pin that I connected seem SDA and SCL....
or labels are referred to pins below?
Best regards

Re: imu 9 dof do not work
Check the resistance between the solder joints in the photo above and the SDA/SCL pins on the breakout.

Re: imu 9 dof do not work
Mike,
all seems ok. maybe problem is sw, I don't know why but i have more then one Wire lib on my PC, at least 3 with different size...
In wich way can I put system in a normal operating scenario?
consider that I installed IDE 1.6.2
Thank you

Re: imu 9 dof do not work
The Wire library comes as part of the Arduino IDE, but each version of the IDE should find the library it needs.
It sounds like you might have a dead LSM303 on the breakout. Send a note to [email protected] with a link to this thread and the folks there will get you a replacement. (#1714)
