4.2 Required items:

Items required (Hardware):

• EB031 ARM board

• EB034 ARM daughter board attached to EB031

• USB Cable

• EB004 LED boards for testing port outputs.

Items required (Software):

• mLoader ARM programmer sof tware (mLoader_Setup.exe):

• mLoader ARM programmer

• Matrix ARM board USB Driver

Items required (Programs):

• Test program (Test.bin)

4.3 Initial Software Set-up.

If C for ARMs is installed then the mLoader files will have been installed already.

If not run and Install mLoader_Setup. exe which will install mLoader, the Ma trix ARM board USB driver, and the Test.bin file.

4.4 Initial USB Driver installation

When first plugged in the board will be detected by the USB bus and reported as a Matrix board. The Add new hardware wizard will then start asking for the USB drivers for the board. The ARM Boar d USB drivers are preinstalled as part of C for ARMs and the mLoader setup. Select automatic and the drivers should be found automatically. If not then point the driver installer to the ‘USB Driver’ folder installed as part of mLoader (C:\Program Files\Matrix Multimedia\mLoader\ USB Driver by default).

4.5 The Test program

1) Run the ‘ARM Test Program’ shortcut from the Matrix Multimedia\mLoader program group.

The ARM Test program will then appear ready to download the test program.

2) Alternatively open the File ARM_TEST.BIN from the mLoader\ARM_TEST folder in m Loader and send the

program.

3) Whilst pressing down the PROG butto n switch (PB2) tap the RESET (P B1) button switch.

This will put the ARM board into programming mode. Release the PROG but ton switch.

4) The LEDs, if attached, will alter to signify programming mode – usually all on.

5) Once the program is sent press the RESET (PB1) button to leave Programming mode and run the test program.

6) Close the ARM_TEST program.

4.6 ARM Test program details

ARM Test program has two stages which are repeated continuously.

1) LEDs on each port light in alternate pairs creating a 1-0-1-0 to 0-1-0-1 pattern.

The pattern repeats 5 times

2) The entire port flashes on and off.

The pattern is repeated 5 times.

3) Check on each port to see that both the alternating pattern and the flashing pattern are correct.

(Excluding B5, D4 and E4-7 – see notes below).

4.7 Important Notes:

• Pins B5 and D4 are used with caution (they are USB pins and using them causes USB issues).

• Port E only uses pins 0-3. Pins 4-7 are analogue only ports which are not used in this test.

• The User test requires the ARM board to have the Matrix OS program loaded onto the ARM device.

If the Matrix OS program has not been loaded, or has been overwritten please refer to the Re-flashing the EB185 ARM Board section in the EB185-30 Technic al datasheet.

If the board is listed as a Matrix board in Hardware manager, and when first plugged in, then the Matrix O S is correctly loaded.

5 Circuit description

The ARM Board solution is made up of two parts:

• A mother board (ARM Board EB031) that allows A RM devices to be programmed and the program to be

executed ‘seamlessly’

• The ARM daughter board (EB034) that houses the ARM d evice on a simple to use board. This allows the user

to program the device using the A RM Board (EB031) and then either use this daughter board in either the A RM board (EB031) for development, or to easily use the ARM daughter board in another project.

The ARM Board (EB031) acts as a programmer and a development board allowing the powe rful A RM process or to be used with other E-Blocks. The following is a description of the features that make up this board.

5.1 Power Supply

The board is normally operated from an external regulated DC power supply of 6V – 9V. This allows full operat io n 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 specified as 6 – 9V regulated DC power supply. When using the USB port to power the board, the user must be aware of the limitati ons 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 b oard 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 ar e 3.3V compatible.

Document code: EB185-30-1

5.2 Programming (hardware)

The ARM Board connects to a personal computer via the USB 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 program m ed via an external programmer using the JTAG pin s available on the ARM device. This is a standard JTA G 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 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 program ming an d use of all the functio ns available on the ARM device.

The ARM Board has 5 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 first 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 multi ple functi ons – such feature s as SPI,

USART communication and analogue to digitial converters. Please see the datasheet of the actua l 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 genera l-purpose I/O with analogue functionality. Therefore all these eight signals have been grouped together, on the fifth d-type connector (J9), which can be used as a fully analogue port.

Please note that the four general-purp ose I/O are also available on the another D-type connector (J8) and care must be taken to ensure that these signa ls 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 below.

5.3 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 find that the driver gets disassociated. In this case you can use this alter nate method:

Turn power to the ARM board off 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.

5.4 Reset Push Button

PB1 provides a reset by pulling the NRST pin low. This will reset the ARM device thus enabling any pr ogram 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.

5.5 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 enab les the USB synchronisation speed to be correct – as stated by the software specification.

The device can also use an internal PLL to set the freq uency for the device. Please see the datasheet of the device for further information regarding usi ng the PLL.

6 Re-flashing the ARM Board

6.1 When to re-flash

Re-flashing is only required if the Matrix ARM OS has been deleted or overwritten, or if an updated Matrix OS file has been released. Re-flashing should o nly be carried out when specifically required a s errors and complications may cause the ARM board to stop functioning until properly re-flashed.

In our experience the device can need re-flashing if you reset the ARM half way through a programming cycle – to prevent this please ensure that you give the PC sufficient time to download your program. The symptoms here are that the ARM board appears to be dead and a PROG 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-flashing. Please refer to the mLo ader documentation for general programming instructions.

If the ARM is a new device it may r equire the default ARM drivers. These drivers are installed by SAM-BA. Please install SAM-BA before installing the USB drivers for the ARM Board.

7.1 Notes:

• The ARM has a 32 bit IO register and 8 Analog ue 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.

• Four of the analogue lines use pins in the 32 bit digital IO port. Four of the analogue lines are separate analogue

• Port E contains the 8 Analogue input lines.

• Pins B5 and D4 are used in USB Communications.

The pin to port allocation does not correspond directly 0-31 with Ports A-D due to the ne ed to place serial communications pins on the same port (Port C). Please refer to the above Port and Pin list when worki ng with the 32 bit IO register.

only lines.

This means that Port E Pins E0-E3 duplicate those of P ort D pins D0-D3. Pins E4-E7 are analogue lines only, not gene ral IO.

Signals on these lines may affect 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 IO position whilst running the program (move it back to USB for programming).
