DEMOJM User Manual
Serial Grapher Application
Visual Components
This PC-based application is included on the DVD-ROM that accompanies
the DEMOJM, and may also be found at:
http://www.pemicro.com/fixedlinks/demotoolkit.cfm.
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 custom 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 as a series of bar graphs. The virtual serial port
exists on several of P&E’s Embedded Multilink designs including the
DEMOJM 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
jumper J4 is 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 buttons. The graphing of data can be
paused and the scale of the X and Y axes can be changed via a tool bar
located in the top right corner of the Serial Grapher Application.
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.

The Bar Graph has four separate bars A, B, C, and D. On each bar a
percentage value is displayed which indicates the current value relative to the
full range. A byte value of $7F (max is $FF) would show up as approximately
