This question isn't really Arduino specific, but sparkfun's user forums don't seem to have a "general help" area - so I figured you would be the best folks to ask.
I have a MMA7260Q accelerometer breakout
from Sparkfun, but I can't seem to get it working properly. I checked out the datasheet, and Tom Igoe's
tutorial. I was originally trying to use the acc. with my arduino, but when I wasn't getting the results I had hoped for, I hooked up the device by itself.
Below is how I connected the device to my breadboard:
VCC - 3.3V
GND - GND
GS1 - GND # for 1.5g
GS2 - GND # for 1.5g
SLP - UNCONNECTED OR GND #tried both
I then checked the output voltages for X, Y, and Z based on the common ground. No matter how I move, shake, or tilt the device, I only see a maximum of 1mV change (which appears random).
I have double, and triple checked my connections.
Is there something that I am missing here, or is it possible that I have a bad unit?
