DEMO9S08SC4 User Manual 13
Figure 5-3: DEMO9S08SC4 Unsecure Application
This PC-based application is included on the CD-ROM that accompanies the
DEMO9S08SC4, and may also be found at:
http://www.pemicro.com/fixedlinks/DEMOQEtoolkit.html.
5.4 DEMO9S08SC4 Serial Grapher Application
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
DEMO9S08SC4 board.
This PC-based application is included on the CD-ROM that accompanies the
DEMO9S08SC4 and may also be found at:
http://www.pemicro.com/fixedlinks/DEMOQEtoolkit.html.
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.
5.4.1 Visual Components
The Bar Graph has four separate bars A, B, C, and D. On each bar a
14 DEMO9S08SC4 User Manual
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:
Figure 5-4: Serial Grapher Bar Graph
The graphing component shows four waveforms X, Y, Z, and W. The
magnitude axis either has a range of $00-$FF (if byte values are incoming 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 move 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 limited size,
so older samples will eventually fall off the left part of the graph. As can be
seen in Section 5.4.2 - Data Format, each incoming data command affecting
the graphing component must have new data for all four waveforms. An
example graph is shown here:
DEMO9S08SC4 User Manual 15
Figure 5-5: Serial Grapher Graphing Component
5.4.2 Data Format
The data format is broken into two sections depending upon whether the
incoming data is in byte format or word format.
5.4.2.1 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 displayed on the
following graph lines : W, Z, Y, X.
AnnBnnCnnDnn
The nn values are 00-FF and correspond in order to the data displayed on the
following bar graphs lines : A, B, C, D.
5.4.2.2 Word Formatted Data
There are three commands which may be accepted. All commands must end
16 DEMO9S08SC4 User Manual
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 follows: X, Y, Z, W.
nnnn=nnnn=nnnn=nnnn
The nnnn values are 0000-FFFF and correspond in order to the data
displayed on the bar graph component as follows: A, B, C, D.

8.2.1 Product Features & Implementation
P&E’s USB Multilink Interface (USB-ML-12) connects your target to your PC
and allows the PC access to the Background Debug Mode (BDM) on
Freescale’s ColdFireV1, HCS08, RS08, and HC(S)12(X) microcontrollers. It
connects between a USB port on a Windows 2000/XP/Vista machine and a
standard 6-pin debug connector on the target.
By using the USB Multilink Interface, the user can take advantage of the
background debug mode to halt normal processor execution and use a PC to
control the processor. The user can then directly control the target’s
execution, read/write registers and memory values, debug code on the
processor, and program internal or external FLASH memory devices.The
USB Multilink enables you to debug, program, and test your code on your
board.
8.2.2 Software
The USB Multilink Interface works with Codewarrior as well as P&E’s in-circuit
debugger and flash programmer to allow debug and flash programming of the
target processor. P&E’s USB Multilink Development Packages come with the
USB Multilink Interface, as well as flash programming software, in-circuit
debugging software, Windows IDE, and register file editor.

HCS08, RS08, and HC(S)12(X) microcontrollers. The Cyclone PRO connects
your target to the PC via USB, Ethernet, or Serial Port and enables you to
debug your code, program, and test it on your board. After development is
complete the Cyclone PRO can be used as a production tool on your
manufacturing floor.
For production, the Cyclone PRO may be operated interactively via Windowsbased programming applications as well as under batch or .dll commands
from a PC. Once loaded with data by a PC it can be disconnected and
operated manually in a stand-alone mode via the LCD menu and control
buttons. The Cyclone PRO has over 3Mbytes of non-volatile memory, which
allows the onboard storage of multiple programming images. When
connected to a PC for programming or loading it can communicate via the
ethernet, USB, or serial interfaces.
8.3.2 Software
The Cyclone PRO comes with intuitive configuration software and interactive
programming software, as well as easy to use automated control software.
The Cyclone PRO also functions as a full-featured debug interface, and is
supported by Freescale’s CodeWarrior as well as development software from
P&E.

9 TROUBLESHOOTING
9.1 DEMO9S08SC4 Is Undetected
Q: The connection assistant indicates that my DEMO9S08SC4 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
DEMO9S08SC4 hardware. If this dialog indicates that the DEMO9S08SC4
hardware is not connected to the PC, the first step is to make sure that the
DEMO9S08SC4 hardware is connected to the PC via a USB 2.0 high-speed
28 DEMO9S08SC4 User Manual
cable. If it is connected, unplug and then plug in the USB cable on the
DEMO9S08SC4 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 DEMO9S08SC4 interface prior to installing P&E’s
Embedded Multilink drivers, Windows will not have been able to find the
appropriate driver and may have disabled the device. The DEMO9S08SC4
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 DEMO9S08SC4 interface is connected to the computer:
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
If the Multilink device does not show up in the device manager, use the driver
installation utility located in the DEMO9S08SC4 Resources CD-ROM. After
driver installation, unplug the DEMO9S08SC4 from the PC and reboot the
PC. When the reboot has completed, connect the interface 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 DEMO9S08SC4
Resources CD-ROM to make sure all files were properly installed. This may
give some indication of what the problem is.
(D) Using a USB Hub
DEMO9S08SC4 User Manual 29
The DEMO9S08SC4 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
self-powered the DEMO9S08SC4 will not work. In general, USB ports located
directly on the PC are high-power (self-powered) ports.
