Magnetometer and Temperature never change #12

Closed scramble45 closed 7 years ago

scramble45 commented 7 years ago

Any ideas why the Magnetometer and the temp sensor values never change?

Results:

Accel: { x: -1.9, y: -1.9, z: -1.9 }
Mag: { x: 0, z: 0, y: 0 }
Non-Tilt-Comp-Heading: 270
Temp: { temp: 18 }
Accel: { x: -1.8, y: -1.8, z: -1.8 }
Mag: { x: 0, z: 0, y: 0 }
Non-Tilt-Comp-Heading: 270
Temp: { temp: 18 }

Only modifications I made to the module was changing the location of where my lsm303c lives on the i2c.

'1d' is the accel '1e' is the mag

'20' is a GPIO expander
