I am using the LSM9DS0 library and simple example found here: https://github.com/sparkfun/LSM9DS0_Breakout
and followed the hook up guide listed on the sparkfun product page found here: https://learn.sparkfun.com/tutorials/ls … okup-guide
I followed the wiring diagram under the Basic Arduino Example tab in the hook up guide with a few small changes because I wanted to use an SPI configuration instead of the I2C example they listed. Firstly, I hooked up the CSG and CSXM pins to 9 and 10 pins(respectively)on the UNO as it said in the arduino example code and grounded them. Next, I hooked up the SDOXM and SDOG pins to the MISO pin on the arduino UNO.
On the first upload of the simple example I got a bunch of gibberish on the serial monitor so i tried different baud values saw that 9600 worked but that only revealed more problems.
The first being that on every upload, the LSM9DS0 WHO_AM_I returned a different response every run with no changes to the code
The second was the readings on the sensors all alternated between two values that never changed (example below).
LSM9DS0 WHO_AM_I’s returned: 0x8004
Should be 0x49D4
G: 99.56, 2.87, 6.79
A: -2.00, -1.81, 0.06
M: 0.02, 0.06, 0.81
Heading: 67.08
Pitch, Roll: -47.71, -42.17

other examples of random WHO_AM_I values are
0x6031
0x6D2
0x1A01
All help is appreciated, thanks a bunch
