6.4 Serial Grapher Application
This PC-based application is a generalized version that may be used with
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 DEMOEM board.
To start using this application, please choose COM or virtual USB COM
settings from the drop-down Port menu. By doing so, you ar e sp ecif yin g th e
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 J7 and J8 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 buttons. The graphing of data can be
20 DEMOEM User Manual
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.
This PC-based application is included on the DVD-ROM that accompanies
the DEMOEM and may also be found at:
http://www.pemicro.com/fixedlinks/demotoolkit.cfm.
6.4.1 Visual Components
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
50% as would a word value of $7FFF (max is $FFFF). As can be seen in the
data formatting section, all four bars must be written at the same time. The
bars are shown here:
DEMOEM User Manual 21
Figure 6-4: Serial Grapher Bar Graph
The graphing component shows four waveforms, X, Y, Z, and W. The
magnitude axis either has a range of $00-$F F ( if b yte value s are in co ming on
the serial port) or $0000-$FFFF (if word values are incoming). Each new set
of values which comes through the serial port is added to the far right side of
the graph and the rest of the data values are moved to the left. The vertical
axis displays the incoming data as the magnitude of each waveform, and the
horizontal axis displays the number of samples. The graph has a lim ited size,
so older samples will eventually fall off the left part of the graph. As can be
seen in Data Format, each incoming data command affecting the graphing
component must have new data for all four waveforms. An example graph is
shown here:
22 DEMOEM User Manual
Figure 6-5: Serial Grapher Graphing Component
6.4.2 Data Format
The data format is broken into two sections depending upon whether the
incoming data is in byte format or word format.
6.4.2.1 Byte Formatted Data
There are two commands which may be accepted. Both commands must end
in the special characters #$0D and #$0A which are CR (carriage return) and
LF (line feed). The accepted commands are:
WnnZnnYnnXnn
The nn values are 00-FF and correspond in order to the data di splayed on the
following graph lines: W, Z, Y, X.
AnnBnnCnnDnn
The nn values are 00-FF and correspond in order to the data di splayed on the
following bar graphs lines: A, B, C, D.
DEMOEM User Manual 23
6.4.2.2 Word Formatted Data
There are three commands which may be accepted. All commands must end
in the special characters #$0D and #$0A which are CR (carriage return) and
LF (line feed). The accepted commands are:
nnnn,nnnn,nnnn,nnnn
The nnnn values are 0000-FFFF and correspond in order to the data
displayed on both the graph and bar graphs as follows: X/A, Y/B, Z/C, W/D.
nnnn:nnnn:nnnn:nnnn
The nnnn values are 0000-FFFF and correspond in order to the data
displayed the graphing component as follow s: X , Y, Z, W.

10 TROUBLESHOOTING
10.1 DEMOEM Is Undetected
Q: The connection assistant indicates that my DEMOEM is undetected even
though I have connected the hardware to my USB port. What should I do?
A: The connection assistant, which displays in either Codewarrior or P&E’s
development software, is a dialog which allows the user to connect to the
DEMOEM hardware. If this dialog indicates that the DEMOEM hardware is
not connected to the PC, the first step is to make sure that the DEMOEM
hardware is connected to the PC via a USB 2.0 high-speed cable. If it is
connected, unplug and then plug in the USB cable on the DEMOEM board
and click refresh in the connection assistant. If the hardware still does not
show up, try the following remedies:
(A) Re-Enable the USB driver
If you connected the DEMOEM interface prior to the installation of P&E’s
Embedded Multilink drivers, Windows will not have been able to find the
appropriate driver and may have disabled the device. The DEMOEM board
shows up in Window’s device manager as a “P&E Multilink,” since it contains
P&E’s Embedded Multilink circuitry. If you unplug and then plug in the device,
Windows will automatically disable it even if you have installed the drivers. To
force windows to try to load the driver again, perform the following steps while
the DEMOEM interface is connected to the comp ut er :
1. Open the Control Panel (Start Button->Settings->Control Panel)
2. Double Click the "System" Icon
3. Select the "Hardware" tab
4. Click the "Device Manager" Button
5. The "P&E Multilink" device will be shown with an exclamation mark
next to it. Double-click this device.
6. Click the "Reinstall Driver…" button and follow the dialog instructions
to have Windows automatically install the driver.
(B) Re-Install the USB driver
DEMOEM User Manual 39
If the Multilink device does not show up in the device manager, use the driver
installation utility located in the DEMOEM Resources on the DVD-ROM. After
driver installation, unplug the DEMOEM from the PC and reboot the PC.
When the reboot has completed, connect the interf ace to the PC with the USB
2.0 cable. Run the software again to see if the interface is now detected.
If you have an error attempting to install the drivers, please view the
installation troubleshooting FAQ on P&E’s website at:
http://www.pemicro.com/faqs/faq_view.cfm?id=89.
(C) Test for installation of the USB driver files
To test the driver installation, use the driver test utility in the DEMOEM
Resources of the DVD-ROM to make sure all files were properly installed.
This may give some indication of what the problem is.
(D) Using a USB Hub
The DEMOEM is a high-power USB device. If a USB Hub is used, it must be a
self-powered hub (i.e., with its own power supply). If the Hub is not selfpowered the DEMOEM will not work. In general, USB ports located directly on
the PC are high-power (self-powered) ports.
10.2 CodeWarrior Installation Fails (WinDriver Error)
