DEMOQE Serial Grapher Application
bar located in the top right corner of the DEMOQE Accelerometer Demo
Application.
This PC-based application is included on the DVD-ROM that accompanys the
DEMOQE, and may also be found at:
http://www.pemicro.com/fixedlinks/demoQEtoolkit.html.
This PC-based application is a more generalized version of the accelerometer
demo application. It may be used with the microcontroller based serial
accelerometer application or customer microcontroller code which transmits
data in the correct format. The serial graphing utility allows incoming data on
the PC serial port, or one of P&E’ s virtual serial ports, to be automatically
graphed in time or displayed upon a series of bar graphs. The virtual serial
port exists on several of P&E’ s embedded USB multilink designs including the
DEMOQE board.
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 the
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. The graphing of
data can be paused and the scale on the X and Y axes can be changed via a
tool bar located in the top right corner of the DEMOQE Serial Grapher
Application.
This PC-based application is included on the DVD-ROM that accompanys the
DEMOQE and may also be found at:

All data to be displayed must be in hexadecimal format. The data can be
accepted and displayed either as incoming byte values ($00-$FF) or word
values ($0000-$FFFF). The data format indicates whether the data is byte or
word data. The graphical components automatically size their range
depending upon the incoming data.
