4.3 Programming the AT90S1200
Testing the Atmel AVR® Board – 90S1200.hex
The following instructions explain the steps to test and use your Atmel AVR® Board. The
instructions assume that AVR® Studio is installed and functional. It also assumes that the test
program 90S1200.hex has been downloaded. This test routine is a step-by-step guide to loading a
programming into the Atmel AVR® Board.
Follow these instructions to test the Atmel AVR® Board
1) Ensure power is supplied to all the Atmel AVR® Board via the power connector J4.
2) Insert EB-004 LED board into Port B of the Atmel AVR® Board
3) Ensure that the Almel AVR® is in correct configuration for programming
- Jumper links for J9, J10 and J11 are in the position marked “DEFAULT”
- Ensure that a 11.052MHz crystal is inserted in the Atmel AVR® Board
4) AVRISP connected to PC and J3 of AVR Board
- Connect RS232 style cable (cable provided) to PC and to AVRISP box (grey
box)
- Connect grey header socket (6-way) to J3 of AVR Board
Ensure the cable is placed with the tab to the outside of the AVR board (this
orientation of the header is shown on the AVR Board silk screen)
For details on AVRISP connector see ‘Programming – Hardware’ in chapter 5
5) Open AVR studio Software
6) Cancel the pop-up window to open any project / files
7) Click on the AVR programming symbol
8) Select AT90S1200 device form “Device” pop-down window
9) Select the “…” button in the Flash section as shown below
10) Navigate to the program 90S1200.hex
11) Press the program button. This will program the AT90S1200 with the test program
90S1200.hex
12) Press the “RESET” button (PB1) on the AVR Board
13) Check the illumination of all LEDs
This should satisfy that the Atmel AVR® Board is fully functional!

Ensuring correct polarity for power supply
Positive Inner/Positive Outer polarity
To set up the correct polarity the connection symbols on the jack need to match those shown
below.
Connector dimensions
The PSU is supplied with a number of connectors.
The correct connector for Matrix Multimedia products
is:
Type D
5.0mm external diameter
2.1mm internal diameter
“D” is marked on one side, down by the pins, and
“5.0x2.1” is marked on the other side.

Positive Outer power supply
The two arrows – one on the connector socket and one on the connector pin, help you select the
correct side of the power jack, and the symbol shows the correct outer connection.

The AVR® Board solution is made up of two parts: A circuit board that allows various slave Atmel
AVR® devices to be programmed, and the program to be executed ‘seamlessly’, and the Windows
based programming utility AVR® Studio.

Power Supply
The board can be powered from an unregulated 14V supply. The regulation circuitry will withstand
unregulated 20V as a maximum input voltage and 7V as a minimum. If you are using a DC power
supply then you should use a 14V setting. Power can be connected using the 2.1mm power jack
(positive outer), or the screw terminal connectors J1, J2. The two “+V OUT” screw terminals are
supplied for powering other E-blocks™, supplying approximately +5V. The regulator will supply up
to 400mA via all outputs. LED D3 will indicate that power is connected to the board and that the
voltage regulation circuitry is fully functional.
Please note connector J4 is directly connected to the J1 screw terminal pin 1 labelled ‘+14V’,
therefore any voltage input to J4 will also be available direct from pin 1 of J1. This means that
‘+14V’ will not necessarily be +14V
Note
Remember that other E-blocks will have to receive +5V by placing a connecting wire from the “+V
Out” screw terminal of the Multiprogrammer to the “+V” screw terminal of each E-Block that
requires a voltage.
Programming - Hardware
The AVR® Board connects to a personal computer via the AVRISP or compatible device. The
AVRISP requires +5V and ground connection these are all provided on the board via the
programming header J3.
The following diagram shows the pin-out of the connector J3. The pin-out is the standard pin-out
as used by AVRISP.

By default the pins RB5, RB6, and RB7 are used to program the slave AVR® device. These are
the pins that provide the programming functions MOSI, MISO and SCK respectively. Due to the
nature of programming it is recommended that programming pins have clean signals when
programming, therefore there are 120-Ohm resistors between these pins and the associated Port
B pins. This is achieved by placing the 3-way link block in the “DEFAULT” mode for J9, J10 and
J11. This provides the adequate protection whilst programming.
If problems occur in the programming sequence we recommend completely removing the 3-way
jumper link on J9, J10 and J11. This allows MISO, MOSI and SCK to be completely clean whilst

programming. This removes the link to Port B, so pins RB5, RB6 and RB7 are only used for
programming.
It is possible to get 100% clean signals on RB5, RB6 and RB7 by placing the 3-way jumper link in
the side opposite to that labelled “default” on J9, J10 and J11. Please note that the AVR® devices
can NOT be programmed when in this state – this state is only recommended if problems with
attachments in Port B occur.
Programming - Software
The CD ROM includes a range of development tools including an Integrated Development
Environment for code writing in assembly and debugging, a professional C compiler, and the ISP
programming software.
DIL Sockets and I / O Ports
The slave AVR® DIL sockets are wired in parallel (see table of connections below) and the ports
are fed out to 4 D-type sockets grouped in ports. These signals are also available on a 40-way
header for expansion purposes. Some of the ports will be inactive. This reflects the pin outs of the
various AVR® devices themselves. For example, the AT90S1200 only has Port B and Port D,
therefore Port A and Port C are inactive. Please refer to device datasheets for availability of port
outputs on each device.
NOTE – Only insert ONE Atmel AVR® device at a time!
Reset Push Button
PB1 provides a reset by pulling the /RESET pin low. PB1 is pulled normally high through a resistor
so that the device will not be reset during normal operation. The programming software has
control over the reset line during programming.
Frequency Selection
By default the board is fitted with a 11.0592 MHz crystal. The crystal fits into a small socket, which
allows the crystal to be easily changed. These frequencies are chosen as they divide down by
AVR® pre-scalers to give suitable frequencies for clock systems and for facilitating serial
communication using standard baud rates.
USB circuitry
In the future there may be a possibility of this device being USB compatible. The PCB has been
manufactured with the circuitry on board to enable quick development.
Note this circuitry is not suppose to be populated

Appendix C - Bus connections
Expansion bus
The pin connections on the expansion bus exactly mirror the pin numbering on the 40-pin DIL socket. Note that the pin numbering on the IDC socket
is slightly different to that on a DIL socket which results in the seemingly odd arrangement of pins on the IDC pin chart.
