General information
This E-block board is a development tool for the powerful
AT91 SAM 7 microcontroller from Atmel. The SAM 7 is
a 32 bit RISC device running at an interval frequency of
36MHz, and having 128k ROM and 32K static RAM as
well as 2 USARTs, 4 x 10 bit A/D converters and a native
USB bus. This incredibly powerful microcontroller can
be used for a range of advanced E-blocks projects. The
board has ve E-blocks ports and the processor itself
is housed on a removable daughter board (Atmel ARM
processors are only available in SMD technology) so that
the ARM can be incorporated into custom PCBs.

Circuit description
The ARM board solution is made up of two parts:
• A mother board (ARM board EB031) that allows ARM
devices to be programmed and the program to be
executed ‘seamlessly’.
• The ARM daughter board (EB034) that houses the
ARM device on a simple to use board. This allow the
user to program the device using the ARM board
(EB031) and then either use this daughter board in
either the ARM board (EB031) for development, or
to easily use the ARM daughter board in another
project.
1. Power supply
The board is normally operated from an external
regulated DC power supply of 6V - 9V. This allows full
operation including programming.
The board has two modes of power supply; either from
an external regulated DC power supply or powered
using the computer via the USB port. The external
power supply is specied as 6-9V regulated DC power
supply. When using the USB port to power the board,
the user must be aware of the limitations for the use of
this USB port - for example the limited current that can
be supplied via USB (approx. 100mA).
The jumper link system, J16, allows the user to decide
on the source of the power supply. If using an external
power supply the jumper should be positioned to the
left hand side of the jumper system labelled ‘PSU’. If
using USB power place the jumper on the right hand
side of the jumper system. LED1 indicates that power
is supplied to the board from either the external power
supply or the USB cable.
Please note that both USB and the PSU cables should
be removed for the ARM board before changing the
position of this jumper.
Remember that other E-blocks will have to receive 3.3V by
placing a connecting wire from the +V screw terminal of
the ARM board to the +V screw terminal of each E-block
that requires a voltage. Also the user should ensure that
all the E-blocks that they are using are 3.3V compatible.
2. Programming (hardware)
The ARM board connects to a personal computer via
the USC socket. Any USB socket on the PC can be used.
The host ARM device is set-up to communicate with the
USB bus and the programming circuitry. The board uses
MOSFET transistors to detect the USB bus, which allows
the board to be programmed.
The board has a connection (10 +10 DIL PCB header pins)
that allows the ARM device to be programmed via an
external programmer using the JTAG pins available on
the ARM device. This is a standard JTAG connection.
DIL sockets and I/O ports
The ARM board uses an external ARM daughter board.
This daughter board enables the ARM board to be both
a development board and a programmer. This means

5Copyright © Matrix Technology Solutions Ltd.
that the user can either use the ARM daughter board in
the ARM board for development, or for programming
the daughter board which can then be used in other
projects.
The ARM board connects to the ARM daughter board
(EB034) via four DIL PCB sockets (10 + 10). These connect
all the ARM device signals to the ARM daughter board,
thus allowing programming and use of all the functions
available on the ARM device.
The ARM board has ve I/O ports, in the form of 9-way
D-type connectors. These allow the ARM board to be
fully compatible with the E-blocks range. The rst four
D-type connectors (J5-8) connect all 32 general-purpose
I/O from the ARM device. Most of these general-purpose
I/O pins have multiple functions - such features as SPI.
USART communication and analogue to digital
converters. Please see the datasheet of the actual ARM
device that you are using for complete list of functions
(www.atmel.com).
The ARM device has four dedicated analogue to digital
converters and four general-purpose I/O with analogue
functionality. Therefore all these either signals have
been grouped together, on the fth D-type connector
(J9), which can be used as a fully analogue port.
Please note that the four general-purpose I/O are also
available on the another D-type connector (J8) and
care must be taken to ensure that these signals are not
connected to any other device whilst using them on these
fully analogue port (J9).
A full table of I/O connections is provided on page 7.
3. Programming (software)
There are two ways of getting the ARM board into
programming mode:
With the power to the board on press and hold down the
PROG button switch. Then quickly press and release the
RESET button switch. If your drivers are set up then you
will hear Windows give a double tone to indicate a USB
device has been discovered.
If you have used D4 or B5 as an output then you may nd
that the driver gets disassociated. In this case you can
use this alternate method:
Turn power to the ARM board o using SW 1. Press and
hold the PROG button switch down. Turn power on with
SW1, and less than half a second after release the PROG
button switch.
4. Reset push button
PB1 provides a reset by pulling the NRST pin low. This
will reset the ARM device thus enabling any program to
restart.
Please note that the NRST can be programmed so that the
reset pin will not function as a reset. See the datasheet
for the ARM device that you are using for more details on
disabling the NRST as a reset.
5. Frequency selection
The clock signal for this board is generated from either an
internal RC clock signal or the on-board external crystal.
The on-board crystal is set to 18.432MHz as this enables
the USB synchronisation speed to be correct - as stated
by the software specication.
The device can also use an internal PLL to set the
frequency for the device. Please see the datasheet of the
device for further information regarding using the PLL.

Re-ashing the ARM board
1. When to re-ash
Re-ashing is only required if the Matrix ARM OS has been
deleted or overwritten, or if an updated Matrix OS le has
been released. Re-ashing should only be carried out
when specically required as errors and complications
may cause the ARM board to stop functioning until
properly re-ashed.
In our experience the device can need re-ashing if you
reset the ARM half way through a programming cycle
– to prevent this please ensure that you give the PC
sucient time to download
your program. The symptoms
here are that the ARM board
appearstobedeadandaPROG
button with RESET button
activation does not work, and
neither does a power up PROG
button activation work.
General programming is performed without requiring
re-ashing. Please refer to the mLoader documentation
for general programming instructions.
If the ARM is a new device it may require the default ARM
drivers. These drivers are installed by SAM-BA. Please
install SAM-BA before installing the USB drivers for the
ARM board.
2. Required items:
• SAM-BA ARM re-ash software. Available on ELSAM
2.0 or later and from ATMEL (www.atmel.com).
• Re-ash programs (ARM_MM.bin and test.bin)
3. Set-up
The ARM board requires re-ashing to put the Matrix
ARM OS onto the ARM board.
1. Re-ashing can be done with USB power only.
2. Check J16 power selector set to USB.
3. Check J18 programming jumper set to USB.
4. Check J15 TST jumper set to Default.
5. Plug the board into the PC and turn the power
switch SW1 to ON.
6. Check that the Green Power LED is lit.
4. Re-ashing process
1. Place the TST jumper (J15) to test position - i.e.
the bottom pins, straddling the Default box
border. Leave for at least 8-10 seconds.
2. Move SW1 to OFF and replace the TST jumper to
the Default position.
3. Move SW1 to ON.
4. Open SAM-BA.

1. Notes
• The ARM has a 32 bit I/O register and 8 analogue
input lines
• On the E-blocks ARM board the 32 bit register
has been broken down into four ports - Ports A,
B, C and D. The pin to port allocation does not
correspond directly 0-31 with Ports A-D due to
the need to place serial communications pins
on the same port (Port C). Please refer to the
table on the left when working with the 32 bit
I/O register.
• Four of the analogue lines use pins in the 32 bit
digital I/O port. Four of the analogue lines are
separate only lists.
• Port E contains the 8 analogue input lines. This
means that Port E pins E0-E3 duplicate those of
Port D pins D0-D3. Pins E4-E7 are analogue lines
only, not general I/O.
• Pins B5 and D4 are used in USB communications.
Signals on these lines may aect the USB bus
causing erroneous activations of the USB
New device added wizard. To prevent this
either do not use Pins B5 and D4, or move the
Programming Pin Select jumper (J18) to the I/O
position whilst running the program (move it
back to USB for programming).
