Today I received my accelerometer from Dimension Engineering, I was so excited and couldn’t wait to start making something w/ it. So I figured I could follow the app note on their web site for making a G-meter.

I figured that I could just do it with the CB220 module and a Plug-N-Play LCD from Comfile in matter of minutes.

The following is the accelerometer’s pin outs from the product data sheet:

The accelerometer has a 3.3V regulator so we can use the 333mV/g as sensitity for our G-meter.

Since the CUBLOC CB220 module has analog inputs, we can simply connect X, Y, Z analog outputs of the accelerometer to the AD pins on the CB220.

Make connections like shown below:

Then, you can connect the LCD using the connectors.
When done, you should have something like above.
Simply download the Accelerometer.zip and download to your CB220 module using CublocStudio.

Now you should be able to get 1G on your LCD readings when you move your study board vertically and horizontally.

Now go to your car and strap the study board on to your center console like this:

And then place the LCD on your dashboard.

When you accelerate, you should see Y increasing and when you decelerate, you should see Y decreasing.

When you turn left or right, you will see X changing.
