Hello, here is an example of how to parse the Ascii Data sent by the SparkFun WiTilt board. This runs on a Macbook Pro with Processing 0124. This example let you move a 3D cube in space according to the 3 axis of the accelero.

The code is not very well written, but it is a start ;) Any comments or improvements welcomed...

The .pde file here

my witilt config is ASCII mode (gravity mode) at 135 Hz...

On mac you can use Zterm to check that everything is ok. You can also program it in processing with port.write but it's not that convivial...

Also, at the beginning, i had a problem with the voltage... I was giving less than 4V to the board (3,3 v cell battery) and it was not working... Now i'm using either 4 AA or directly a modified USB cable that gives 5/6 Volts directly to the board. It's been two month and the board is still on

My friend leah buechley is also using soft battery, you can find them at Sparkfun i think...

I'm currently working on optical-inertial tracking and still struggling with Extended Kalman Filters, any help would be cool

cheers,
j*b
