ST7-EMU3
series emulator
Introduction
Thanks for choosing ST7! This manual will help you set up and start using your ST7-EMU3
emulator.
The ST7-EMU3 emulator is the latest generation of ST7 emulators. In combination with the
ST7 debugging and programming software, it gives you unprecedented control of
application development - from building and debugging your applications to programming
your ST7 microcontroller.
The ST7-EMU3 emulator gives you start-to-finish control of application development by
providing you with emulation and in-circuit communication (ICC) configurations. The ST
Micro Connect box is your common hardware interface for emulation and in-circuit
debugging and programming.
In the emulation configuration, your emulator’s probe and ST7 Visual Develop (STVD7)
software allow you to build and debug your application software. This configuration gives
you the most complete range of debugging features, including advanced breakpoints and
performance analysis.
In the in-circuit communication configuration, the ICC Add-on and STVD7 allow you to
debug your application while it runs on your ST7, and to program your ST7 microcontroller
with ST7 Visual Programmer (STVP7).

3 Connectivity
The ST Micro Connect box provides three possible connections to the host PC:parallel port,
USB and Ethernet. The type of connection that you use will be determined, in part, by the
configuration you choose for your EMU3 emulator.
In the in-circuit communication configuration, you can use either the USB or the parallel
port. Ethernet is not supported in this configuration. In the emulation configuration you can
use the Ethernet, USB or parallel port.
When you start your emulation, in-circuit debugging or in-circuit programming sessions, you
will have to set the connection type in STVD7 or STVP7. In STVD7, set the port in the
Debug Instrument Settings window (Debug Instrument>Target Settings). When
programming your ST7 with STVP7, set the port in the Configuration window
(Configure>Configure ST7 Visual Programmer). For more information refer to your
software's online help.
The following sections provide you with information about supported connections, as well as
how to connect your PC via:

3.3 Ethernet connection
Your EMU3 emulator supports 10 MHz Ethernet connections when set up in the emulation
configuration. When you program with the ICC Add-on, use the parallel or the USB port.
For Ethernet connections, you must first give your ST Micro Connect box an IP address in
order for it to be recognized as a device on your network. If your ST Micro Connect box has
not been assigned an IP address, refer to Section 3.3.1 on page 12 for detailed instructions.
Figure 10. Ferrite for Ethernet cable
Once you have assigned an IP address to the ST Micro Connect box, connect it to your
network using the Ethernet connector on the rear panel. To reduce signal noise, you should
attach the provided ferrite to your Ethernet cable as shown in Figure 8. The ferrite should be
placed as close as possible to the end that is plugged into your ST Micro Connect box. The
Ethernet cable is not provided with your EMU3 emulator.
3.3.1 Assigning an IP address
To give your ST Micro Connect box an IP address do the following:
1. Connect the provided serial cable between the serial port of your ST Micro Connect
and a serial port on your PC (either COM1 or COM2).
Note: To set the IP address, you must use a direct serial cable like the one provided (i.e. the PC-
side Receive Data pin (Rx) connects directly to the emulator-side Rx pin and the PC-side
Transmit Data pin (Tx) connects directly to the emulator-side Tx pin). You cannot use a
serial cable with an inverted connection (Rx pin connected to Tx pin).
2. From Windows, open a Hyperterminal window. This is done by selecting
Start>Programs>Accessories>Communications>Hyperterminal.
3. If the Hyperterminal software is not installed on your system, you will have to install it
from your Windows®CD-ROM, by selecting Start>Settings>Control
Panel>Add/Remove Programs>Windows Setup, and clicking on the Hyperterminal
option.
4. The Connection Description dialog box will open. Type in the name you wish to give

●emulator status LEDs,
●26-pin ‘Ext Link,’ for ICC connection,
●ports for two 80-pin flat cables that connect the ST Micro Connect box to the EMU3
probe.
The three emulator status LEDs on the front panel of the ST Micro Connect box indicate the
state of the development tool during emulation:
●Reset (Red)—indicates that the ST7 emulation chip is being reset. In addition, there is
one LED on the EMU3 probe, near the ST Micro Connect connectors, that lights when
data is being communicated between the ST Micro Connect box and the EMU3 probe.
●Wait (Yellow)—indicates that emulator is in halt or wait for interrupt mode.
●Run (Green)—indicates that the ST7 application is running (the ST7 is not in RESET,
WFI or HALT mode).

4.3.2 Probe connection cables
The ST Micro Connect box connects to your EMU3 probe via the two 80-wire flat cables
coming from the front panel. When you receive your emulator, the ST Micro Connect box
and the probe should already be connected (see Figure 19).
Figure 19. Connecting the 80-pin cables to the EMU3 probe
To disconnect or reconnect the cables, do the following:
To disconnect the probe
1. Power off your application board and the ST Micro Connect box.
2. Unplug the long, 80-wire flat cable that is connected to port number 2 on top of the
probe. Grasp the sides of the plug, squeeze to release the two metal locks and pull
upwards, unplugging the cable from the port.
3. Unplug the short, 80-wire flat cable that is connected to port number 1 in the same
manner.
To reconnect the probe
Plug the 80-wire flat cables back into their ports.
●The short 80-wire flat cable (bottom) always plugs into port number 1.
●The long 80-wire flat cable (top) always plugs into port number 2 (see Figure 19).

4.3.3 Power supply
The power supply for your emulator connects to the rear panel of the ST7 Micro Connect
box (see Figure 18). When you connect the power supply be sure to:
1. Ensure that the operating voltage (110 Volts/220 Volts), which is indicated on the label
on the power supply, matches your mains supply. Contact your dealer if this voltage
does not correspond to your mains supply.
2. Connect the external power supply provided with the emulator to the rear panel of the
ST Micro Connect box using the 5-pin DIN connector.
3. Plug the power supply into the mains using the supply cable provided.
AC voltage: 100 V to 240 V
Frequency: 50 to 60 Hz
4.3.4 Output and Input triggers
Your ST Micro Connect box has two output triggers (OUT1, OUT2), and one input trigger
(IN), which are available via SUB-click connectors located on the front panel (see
Figure 17). Both input and output signals are at TTL level.
Advanced Breakpoints in STVD7, allow you to define an event based on input signals (see
also Section 4.4.3 on page 22), and program signals to the output triggers.
The following trigger output modes (schematically represented in Figure 20) are supported:
●Output a pulse—where a signal of value 1 is sent during exactly one memory cycle.
●Toggle—where the signal value is changed from 0 to 1 or from 1 to 0.
●Set the output high —where the output signal is set equal to 1.
●Set the output low—where the output signal is set equal to 0.
Several examples of how to program Advanced Breakpoints to control the sending of signals
to the output triggers are given in STVD7’s online help and user manual.
