Hello
(Warning: I’m relatively new at this)
I am trying to read values from a MMA7361L accelerometer through my mini maestro 12 channel however I’m starting to think there’s more to it than connecting the wires. Here is what I’ve done so far (no soldering and for now, using the Maestro control centre):
Wiring
- Mini maestro connected to pc through mini usb cable
- External power source(+/- 5V) connected to servo pins
- Channel 4 is set as an input and connected to the x-axis of the accelerometer.
- VDD of the accelerometer is connected to the 5V pin on my maestro
- Channel 5 is configured as an output and connected to the sleep pin on the accelerometer (it is set at high input signal)
What happens:
When this is set the reading on the input channel 4 jumps around 233-236 and is totally unresponsive as I tilt the accelerometer. When I connect the ground to the accelerometer it just reads the value 0 unchanging. I can’t manage to get any readings with a multi meter at the accelerometers x-,y- and z-axis pins.
Now could you please tell me what is wrong here and how to fix it, or just how to interface the MMA7361L.
It will be greatly appreciated!!
