1. You don't need to install any driver. The SensorStick will be recognized as a modem. Download the Mac Standalone Control Program. Unzip it, a program called "SensorStickMac" should be created. It is located now at Download folder. You can move it anywhere else at your convenience. Before you can run the program, you need to install mono and X11.
   

2. Now you can double click the  "SensorStickMac.command" in Finder. The rest is the same. Notice the this release on Mac is not as stable as it is on Windows. If some error occur, just close it and unplug the SensorStick. Then double click the  "SensorStickMac.command" to start over .

   This GUI offers full control of our SensorStick. A list of available COM ports will be given in the dropdown list. When the right one is chosen, a "device connected" message will be shown at the bottom. All six types of sensors can be turned on/off and the sampling rate can be adjusted. Two modes are available: * Multimeter: time averaged data will shown directly in the box on the GUI.  Users may find this mode most convenient while recording data from experiments.  * Time series: a new window will pop up exhibitng sensor data versus time plots. Users may find this mode most useful when only qualitative behavior is required (like demonstration) .

   
   
3. After the correct communication port is selected. Control buttons will be enabled. Click "Config&Run", the sensorstick will start collect data which will be displayed depending on the chosen mode. If time series mode is chosen, the following data plots will be shown on the screen. These are real time sensor data.
   
   
   
   
   Users can interact with these plot intuitively. For example, if users drag a mouse on each axis, it behaves as a zoom in/out. The plot region can also be dragged to move up/down/left/right. Further, you can manually set the min/max value of each y axis.
   If users want to save data in a file, click the "save" button before clicking the "Config&Run" button. In "Duration" mode, the file will be closed automatically after the preset time runs out. In "Load&Go" mode, however, users could close the file manually if they decide to stop saving.

Notes

Note that there is a text file "calib.txt". This file contains calibration information for accelerometer and magnetic compass. All the other sensor outputs are raw 10 bit digital values. Users can calibrate all the sensors themselves. For suggested calibration values, please refer to the Excel file "calib.xls".  

The format of the file "calib.txt" is as follows:
The first line is the offset of accelerometer in three directions (x y z in sequence): meaning the output value representing true zero.
The second line is the scale needed to adjust the output to units of acceleration owe to gravity, g
The third line is the offset for magnetic compass
The fourth line is the the scale to adjust the compass output
Users can measure these calibration values themselves. The default input file is as follows
0 0 0
1 1 1
0 0 0
1 1 1
In this case, the file values result in no calibration and the output is the raw sensor digital data.

Or, you can use the calibration values in the Excel file calib.xls. Refer to the serial number on the SensorStick to look up the appropriate values.

If you decide to use the calibration data, the default display range (0~1024) may need to be adjusted to show the calibrated data. For example, the value given in the calib.xls will calibrate acceleration data to vary from about -2 to 2 with unit g (gravity). So you should adjust the min/max value of y axis accordingly.
