7.5 Using the uC/Probe Example Workspace
µC/Probe is a Windows program which retrieves the values of global variables from a connected
embedded target and displays the values in an engineer-friendly format. To accomplish this, an ELF
file, created by the user’s compiler and containing the names and addresses of all the global symbols
on the target, is monitored by µC/Probe. The user places components (such as gauges, labels, and
charts) into a Data Screen in a µC/Probe workspace and assigns each one of these a variable from
the Symbol Browser, which lists all symbols from the ELF file. The symbols associated with
components placed on an open Data Screen will be updated after the user presses the start button
(assuming the user’s PC is connected to the target).
To use µC/Probe with the example project (or your application), do the following:
 Download and Install µC/Probe. A trial version of µC/Probe can be downloaded from the
Micriµm website at
http://www.micrium.com/products/probe/probe.html
 Open µC/Probe. After downloading and installing this program, open the example µC/Probe
workspace for µC/OS-II LPC3250-Phytec-OS-Probe-Workspace.wsp, which should be located in
your project directory at:
\Micrium\Software\EvalBoards\NXP\LPC3250-Phytec\IAR\OS-Probe
 Connect Target to PC. You should connect a RS-232 cable between your target (upper RS-232
port) and your computer.
 Load Your ELF File. The example projects described in this QuickStart are already configured
to output an ELF file. (If you are using your own project, please refer to Appendix A of the
µC/Probe user manual for directions for generating an ELF file with your compiler.) This file
should be in
/<Project Directory>/<Configuration Name>/exe/
where <Project Directory> is the directory in which the IAR EWARM project is located
(extension *.ewp) and <Configuration Name> is the name of the configuration in that project
which was built to generate the ELF file and which will be loaded onto the target. The ELF file
will be named
<Project Name>.out
To load this ELF file, right-click on the symbol browser and choose “Add Symbols”.
 Configure the RS-232 Options. In µC/Probe, choose the Options
menu item on the Tools
menu. A dialog box as shown below, left, should appear. Choose the RS-232 radio button.
