Figure 6-4: Accelererometer Demo Application
The data that is graphed may come from either the PC serial port or the virtual
serial port on the DEMOQE board. The serial port of the microcontroller on
the DEMOQE board is routed to either serial port hardware or the virtual COM
port based upon the setting of jumpers J6 and J7. To properly configure
accelerometer and potentiometer resources on the DEMOQE evaluation
board, please make sure that these headers are populated with jumpers in
the following manner: J16 (Z/PTA7 -populated, Y/PTA6 –populated, Y/PTC7
-populated, X/PTA1 –populated); J14 (set to 0); J16 (set to 0); J15 (set to 1);
J21 (PTA0 –populated, PTC6 –populated).
To start using this application, please choose COM or virtual USB COM
settings from the drop-down Port menu. By doing so, you are specifying the
port on the evaluation board that will be used for transmitting captured
accelerometer data via a COM or USB serial port. Please make sure that
jumpers on headers J6 and J7 are set accordingly. Prior to starting serial data
capture, please specify the Baud setting to reflect the parameter at which your
serial communication interface is operating. Once your port settings are
configured, please plug a USB or DB9 serial cable into the evaluation board
and click on the Open Serial Port and Start Demo button. After the serial data
is captured by the application you will see raw data in the Terminal Window.
In the meantime, the Data Snapshot window will display the accelerometer
and potentiometer data levels in the form of a bar graph. The graphing of data
can be paused and the scale of the X and Y axes can be changed via a tool
