In a project I'm working on at school I could only get static acceleration from the 3-axis accelerometer I have (MMA7361L). I used a simple set-up (4 pins: Tx, Rx, power and ground). As far as I understand, accelerometers are able to detect both types of acceleration but I don't know why I only get variations of data only when I tilt the sensor, not when I move itf from point A to point B. Can anybody point me in the right direction? what am I doing wrong? thanks a lot.
