6.1 Project s
6.2 Files
If you have used a high-end professional development system, you will be familiar with
the project concept. Essentially, this is a collection of details and data which are managed by the program on your behalf. In the AVR, you have both Program Memory and
non volatile Data Memory (EEPROM), with various security and device options. The
project manager keep s thi s information together for y ou so y ou don't hav e to remember
and reload all the various files every time you use the programmer.
The project manager will all ow you to store inform ation like the project nam e and the
project identifier. It also has a small notepad for you to store comments about the
project.
Before you can start a programming session, you must either open an existing project or
start a new project. You can op en a pr oject, or create a new on e, by e ither goi ng to th e
Project menu and selecting “New” or “Open”, or by using the “New Project” or “Open
Project” buttons on the toolbar.
Once a project is open, you can load the files that you need to program into the device.
Files may be loaded by either using the “Load” command in the File menu or by using
the “Open” icon on the toolbar.
The program will automatically decode your files whether they are in Intel Hex format,
Atmel Generic , Binar y o r Motor ola S rec ord . The file y ou c hoose wil l be loaded into the
window, then it is displayed on the top of the desktop. Therefore, if y ou have the
EEPROM Data Memory window on top, it will load the data into that window.

Programming Using the Board
7.1 Device Orientation
7.2 Voltage Selection
Before programming a devi ce using the prog ramming modul e, the device adap ter must
be inserted c orrec tly int o the pr ogramm ing un it. The a dapter itsel f has a c orner cut-off ,
which locates pin 1 of the device and matches the marking on the main uni t. This
adapter should be prefitted, bu t can be replaced if th e device programming life is
exceeded—refer to your supplier to obtain a new device adapter.
The orientation of the devi ce is vitall y i mportan t. If yo u put it in the wr ong way then you
may damage the device. DO NOT PLUG A DEVICE ADAPTER IN WITH THE POWER
SWITCHED ON or you ma y d ama ge i t. S imil arly , n eve r remov e t he d ev ice adapter with

The power supply 9-15V DC or 7-12V AC is plugged into the power connector 5.5/2.1
Barrel.
The Power On/Off switch is located next to the power connector. Insert the device
adapter before switching the power on. The power on LED should light when the power
is correctly applied.
Your hardware is now ready for programming. Refer to “How to Use the Software” on
page 6-1 for details of programming operations. A programming LED indicates programming is happening.

Brown-Out Detector
The brown-out detector cir cuit is used to detect vol tage drops . If a sh ort gli tch occ urs in

randomly.
The brown-out detector mu st be set to the sam e voltage a s the circuit voltage, V

Board Applications
9.1 Using Switches and LEDs
9.2 Using External Connections
The LEDs are connected through a 1K resistor network to Port B.
The switches are connected to Port D.
The switches an d LE Ds can be di sco nnecte d, if requir ed. To use them, ens ure that th e
jumpers labeled “Port B” and “Port D” are closed. The board is also marked with the port
pin connection for each switch and LED.
The ports must be correctly set in software as input or output. This is accomplished by
setting the direction control r egister s to 0 for i nput and 1 for output. Ty pica l set-up c ode
would be:
ldi r16,$ff ;move immediate into temporary store register
out DDRB,r16 ;set direction register to ones for output -
LEDs
out PORTB,r16 ;switch all the LEDs on
ldi r16,$00 ;move immediate into temporary store register
out DDRD,r16 ;set direction register to zeros for input
Switches
All the ports are brought out to headers on the edge of the boar d. In additi on to the port
pins, each header has a connection for ground and V
this voltage, V
and the brown-out detector will operate.
Note:
If your circuit is to draw significant current (>150 mA) then a heat sink will be
required on the on-board regulator—LM317. This device is rated at 1.5 amps
but it does need a heat sink to supply this current. If your circuit will draw more
than 1 amp, you may need a separate power supply. The ports on the device
are connected to the headers marked Port A, Port B, Port C, Port D, Port E and
Analog, Port F. The layout of all the headers is the same and is shown in the following diagram.

9.4.1 RAM Recommendations
9.4.2 RAM Socket Pin Layout
To use the A/D converters with an external Voltag e Reference, the li nk marked “LK1”
must be cut. The voltage is applied to the pins marked “Analog Ref” and “Analog Gnd”
on the Analog header—see previous diagram.
The ATmega103 can be used with external SRAM. A socket is provided for a 28-pin
RAM chip and for an address latch chip. These are next to the device adapter at the top
of the board. There is also a he ader for furt her mem ory expan sion, whi ch is conn ected
through the address latc h. The pin functi ons are marked on the board, includi ng chip
select (CS).
A low power 62256 SRAM is suggested with an access time of 70 nS. If a very fast RAM
is required, the crys tal frequ ency may nee d to be incre ased. If a muc h slower SRAM is
used, the SRAM Wait State bit must be enabled in user software–—see data book. The
layout of the 28-pin RAM socket is shown below, and any RAM with this pin-out could
be used.
9.4.3 Address Latch
The board connections ar e for a 74HC573 device. This dev ice will ope rate reliab ly with
the 4 MHz cr ystal su pplied but i f a faster crystal is ins erted, a f aster ver sion of th is
device may be required—74AHC573 or 74FHC573. Note that this option will alter the
EMC characteristics of the board and the CE mark will no longer be valid
without retesting.
9.5 Using LCD Connections

The board is designed for use with a LCD with a Hitachi driver chip built-in, with a contrast pin voltage of 0 to 5 Volts. The pot next to the LCD connector is used for contrast
adjustment.
If you use a different LCD driver, it may have a different voltage contrast range. In order
to accommodate this, add a resistor to the board (shown on board) and cut track on
underside of board—marked cut.
This board is not designed for use with back lit LCD modules , so the extra c onnections
needed are not included and the power supply will not supply the current required.
The LCD must be driven in Memory Mappe d Mode as Read and Wri te are descite pins
on the Mega parts—see data sheet. If the crystal has been changed to a faster crystal
frequency, memory mapped operations will not work.
9.6 Using RS232
9.7 Programming InSystem
The connection supplied is a 9-way female D-type, so a straight-through lead is
required, not a null-modem cable.
The Jumpers in the middle of the board, marked PE0 and PE1 must be set to RS232,
not Port or RXD and TXD will be disabled.
As this board has a 4 MHz crystal , the percentage error on the Baud Rate will be
between 0.2 and 7.8%. Replacing the crystal with a 3.6846 MHz or 4.608 MHz crystal
will reduce this error to zero but may have EMC implications.
A standard (straight-through) lead is required, NOT a null-modem cable.
Devices can be programmed in your circuit rather than on the board.
For In-System Programming , ISP, the 10- conduc tor ribbon cable is co nnecte d to a dual
row 10-pin 0.1" pitch header on your circuit.
You will need to use either a multiplexer chip, such as a 4053, or wire directly to the pins
of the device. Without a multipl exer chip , Serial Co mmunications and SPI por t will b e
unusable.
In addition, the syste m 5 Volts an d Ground nee ds to be connec ted to the pr ogrammin g
lead.
DO NOT EXCEED 5 VOLTS ± 5% (4.75V TO 5.25V). YOU MAY DAMAGE YOUR
COMPUTER. THIS WARNING APPLIES TO ANY ISP SYSTEM.

USER
CIRCUIT
Typical resistor values would be 1K. This circuit is fine if ports PB7, PE0 and PE1 are
used as inputs in your circuit and no communication is required. If Outputs are needed
or RS232 connections , especiall y higher than a few mill iamps, th en the multipl exed circuit is preferable.

CONNECTOR
TO USER
CIRCUIT
The multiplexer select can be driven from the LED connection on the programming lead,
as can a low power LED with its cathode connected to the LED connection via a suitable
resistor. 1KΩ is fine. If you use this connectio, then the output will be low 0 during programming and a 1 at all other times. Note that it will float if the programmer is not active,
i.e., the software is not running, so you may need to use a pull-up resistor.

9.10.1 Using Real Time Clock
Note:
A 32.768 kHz crystal is connected to TOSC1 and TOSC2 pins—Pin 18 and Pin 19. This
can be used to generate a 1 second pulse—see data book for details.
All the pins except ground will float if the programmer is not active. The device
may then be programmed in the normal way.
