2. PC System Set-up

Note that the details here may vary from Operating System to Operating System. If the PC has been configured for use on a Local Area Network you may need to configure the PC to have a set IP address, and to not use Proxy server s.

Page 6

To find the IP address of a PC do the following:

1) Go to START -> RUN and type in ‘CMD’ and click on OK.

2) A black DOS prompt window will appear.

3) Type in ‘ipconfig’ and press Enter.

4) The IP address will be listed in the data provided.

5) Type in Exit and press enter to close the window.

Document code: EB023-30-1

The IP address can be set up in the Network Connections dialogue. Open the Network Connections icon in the Control Panel. Select the Local Area Connection item and right click and view its properties. Select the TCP/IP entry in the list and click on the Properties button. Go to the Alternative Configuration tab, select ‘User configured’ a nd enter the IP address obtained from the ipconfig program into the IP address. Click on the Subnet mask and the default 255.255.255.0 setting should appear. If not you can add it manually.

Here we have set the IP address for this PC to 192.168.0.16.

The LAN proxy server setting can be found in the Internet options control panel. Ensure that Use a proxy server is not ticked.

3. Test Procedure

This test routine will test the functionality of the three main protocol layers (MA C, IP, TCP).

The program will send an HTML webpage from the PICmicro® to the computer via the Internet board and the connecting cable.

Visual clues will appear on the LCD display to ensure that the program is running.

1) Set up the Internet system as outline above

2) Apply power to Multiprogrammer board.

3) Download the test pr ogram .

4) Press Reset bu tton o n Mult ipr ogra mmer

1. LCD display will display “Starting up…” and then “Complete” once the TCP/IP connection is established.

5) Open up your Web browser

1. Note: Your home page may not open properly as it is not connected to your network

6) Type the following IP address in to your web browse r: htt p:// 192.1 68.0. 2

1. The LCD display will show “Sending HTML” during transmission.

7) To ensure that the page is vali d and curren t (i.e. not stored in yo ur compu ters memor y) you need to refresh the page. Press the “Refresh” button in your Web browse r

8) The “page request” number will increment when the page is refreshed (with a rollover back to 1 upon

reaching 9)

This will confirm that the Internet Board is fully functional. If you have problems with the refresh sequence repeat from step three above.

Troubleshooting

1) LCD fails to display “Starting up…”

1. Check power, connections, chip and check tha t the correct program has been downl oaded to the device.

2) Displays “Startin g up…” but not “Complete.”

1. TCP/IP connection not established

2. Check Internet board has power.

3. Check cross-over cable.

3) Are the Internet board and Ethernet connection LE D’s flashing at all?

1. If they are then there is an IP Address or socket issue.

2. Check if PC has IP Address 192.168.0.2 and this m ay cause a conflict with the one assigned to the Internet board.

4) Can you Ping the Internet board?

1. Use the Command prompt and enter “Ping 192.168.0.2”.

2. Check the onboard jumpers are set correctly

3. If using the patch system verify that the patch connections have been set up correctly.

5. Circuit description

The circuit as can be seen in the circuit diagram below (See Appendix 1 – Circuit diagram), made up of three main components: the Hardware TCP/IP sta ck I C, the volta ge regu la tio n and select ion s yst e m, and the Patc h system .

1. Hardware TCP/IP stack IC

The Hardware TCP/IP stack IC used is the Wiznet Internet Module NM7010A (formally IIM7010A) IC. The TCP/IP stack IC is an all-in-one network module, ideal component to develop Internet enabled systems. The module communicates via a standard I communicate with the module, enabling a quick development time.

The I

C connection uses a 7-bit address to identify each specific target. The three Least Significant Bits of the address for the Internet module are set using the three jumpers J8, J9 and j10. This allows the use of up to 8 individual Internet boards on the same network system. For further information on the TCP/IP stack IC please see the datasheet provided on the CD.

2. Voltage regulation / selection system

The TCP/IP stack IC requires a core voltage of +3.3Volts. However the I/O lines are +5V tolerant allowing the board to run from either a +5V system or from a +3.3V system. The board can be used with a +5V system (i.e. EBlocks PICmicro Multiprogrammer) or a +3.3V system (i.e. E-Blocks FPGA Board). An on-board voltage regulator is used to generate the +3.3V required by the TCP/IP stack IC.

The board is supplied with a jumper link (J5) which allows the user to select which voltage system they ar e using. The user must position the jumper link in either the “+5V” or the “3.3V” posi tion as labelled on the PCB.

C compatible bus. This means that most processors ca n easily and rapidly

3. Patch system

The Internet Board, like all E-Blocks , is designed with flexibility in mind. Therefore the Internet Board can be used with any ‘upstream’ processor board. To facilitate this a patc h system has been pr ovide d on th is boar d. This patch system allows the use to either select the default setting of the board (gene rally used for PICmicro® microcontrollers) or to wire the connectors to any pins of the D-Type connector that they require.

The communication between the Internet board and the ‘Up-stream’ processor board is via an I

C compatible bus

(SDA and SCK signals).

4. Default settings (A or B)

To use the default setting of the Internet board, the jumper links should be placed on hea der pins J6. Jumper setting A and B are used for selecting the appropriate pins for SDA and SCK, the dedicated I these jumper settings route the interrupt line from the Internet board to bit 0 of the ‘Up-stream’ device.

Headers pins J3 are provided to allow the use the patch settings.

The microcontroller that is being used determines which port and which jumpers are used. For example, if a PIC16F877A is being used, the Internet board must be connecte d to Port C, with the jumper settings to A. The following tables illustrate the c orrect jumper settings.

C compatible lines. Both

Note: The TCP_IP Flowcode component requires MI2C (Master I

C). If you wish to use standard I2C devices, such

as the PIC16F88 you may need to create your own C/ASM code.

5. Using splitter cables

Splitter cables can be used to connect more than one Internet board to a single programmer. The SDA and SCK lines need to be the same for each board connected to the spl itter ca ble. However each board requires a separate interrupt line. Due to this constraint you will need to use the pa tch system when using more than one Internet board on a splitter cable.

• SDA – patch to same Pin (C4 or B1 etc.)

• SCK – patch to same Pin (C3 or B4 etc.)

• INT – patch to different Pins
