2 Hardware Features

2.1 Evaluation Board Features

The EVBQE128 board features:

1. An “MCU” section containing:

 An 80-pin LQFP socket accepting either the MC9S08QE128 or the MCF51QE128

microcontroller;

 A crystal oscillator, a provision for a clock module, a provision for a connector for

providing an external clock source, together with jumpers to select the clock
source;

 A BDM connector for in-circuit debugging/programming with an external

instrument;

 A female header connectors with all of the MCU signals.

2. A power supply section containing:

 A 12 V DC barrel input connector (2.1 mm);

 A four-way micro terminal block for providing specific power supplies and voltage

references to the microcontroller;

 A jumper to select the power supply source (USB bus or barrel connector);

 A power on/off switch.

3. A built-in “microDART INTERFACE” section (with the main circuitry mounted on the
back of the board) which allows the host PC to communicate with the microcontroller
through a standard USB interface. Jumpers are present to configure this module.
Thanks to the microDART in-circuit debugging firmware, BDM commands are sent to
the target microcontroller through the USB bus. Additionally, a virtual COM port is
automatically available over the same USB connection. This virtual COM port can be
used by standard terminal programs, like HyperTerminal, to send/receive serial
characters to/from the target microcontroller.

4. An “I/O” section containing:

 A Reset push-button;

 Four additional push-button;

 One potentiometer;

 Eight dip-switches;

Page 7

Hardware Features

 A piezoelectric buzzer;

 A light sensor;

 A temperature sensor;

 Ten user LEDs;

 A circuitry for driving and external LCD;

 A series of jumpers to connect/disconnect the above controls to/from the

microcontroller.

5. An “RS-232” section containing two RS-232 connectors together with a jumper to enable
the RS-232 communication.

6. A “SERIAL SETTINGS” section containing jumpers to select communication options.

7. A prototype area.

2.2 microDART Interface

Thanks to the microDART in-circuit debugging firmware, CodeWarrior can send BDM
commands to the target microcontroller through the USB bus.

Page 8

EVBQE128 User's Manual

Additionally, when you plug the USB cable into the PC, a “virtual” COM port is automatically
created and, through this port, serial data can be transferred to/from the target microcontroller.
In other words, a terminal application such as HyperTerminal is able to use the virtual COM
port as if it were a normal COM port and send and receive characters normally.

This serial communication and BDM communication work simultaneously: CodeWarrior can be
used to work with the target microcontroller while HyperTerminal sends and receives
characters.

2.2.1 Hot Plug-In

The “Hot Plug-In” feature gives you the possibility to connect to a target microcontroller that is
running an application and to trace and debug the current running code without the need of a
complete erase and re-program of the flash memory.

9 Troubleshooting

9.1 USB Driver Problems

If you connected the Evaluation Board to the PC before installing CodeWarrior, the Evaluation
Board’s USB drivers may not have been correctly installed on your system. Unplugging and
replugging the USB cable is of no use, since Windows has marked the devices as “disabled”.
As a consequence, the PC cannot communicate with the Evaluation Board.
To restore/upgrade the USB drivers (provided CodeWarrior has been installed), perform the
following steps under Windows XP:

1. Connect the Evaluation Board to the PC.

2. Open the Control Panel (Start > Settings > Control Panel).

3. Open the “System” options.

4. Select the “Hardware” tab.

5. Click the “Device Manager” button.

6. Two “EVBQE128” devices will be shown with an exclamation mark next to it.

7. For each device, double click on it and, in the “General” tab, click the “Reinstall

Driver” button. Follow the on-screen instructions.

9.2 Communication Problems between the PC and the
Demo Board

1. Make sure that the “BKGD” and “RESET” jumpers in the “USB” section are inserted.

2. Make sure that the microcontroller is powered:

 Make sure that the “ON-OFF” switch in the “POWER SUPPLY” section selects the

“ON” position;

 Make sure that the “POWER SEL” jumper in the “POWER” section selects the

appropriate power supply source.

9.3 Problems with RS-232 Communication

The Jumper J205 allows the user to control the state of the RS-232 transceiver: when the
position 1-2 (“ON”, default position) is selected, the RS-232 transceiver is enabled (with the
aid of an external pull-up), but the user has the option to turn the transceiver off (on) by driving
the PTG0 line of the microcontroller low (high).
When the position 2-3 (“OFF”) is selected, the RS-232 transceiver is powered off via

Page 31

EVBQE128 User's Manual

hardware, without the need of any microcontroller action, in order to minimize the power
consumption of the board.

In order to communicate via the RS-232_2 COM port, you must remove the “ACMP2-ENA”
and “ADP0/ACMP1+ ENA” jumpers. These pins are shared with other I/O functions that can
generate hardware conflicts with the RS-232 communication.
