1 Lab4 INTRODUCTION TO PICDEM NET2 DEVELOPMENT ENVIRONMENT EET 4730 By Dr. Ece Yaprak Dr. Ece Yaprak 1

2 Purpose The PICDEM.net 2 Development Board allows students to begin developing Internet connectivity applications over an Ethernet connection. Various configurations for Ethernet/Internet Communication Systems. Dr. Ece Yaprak 2

3 Network Precautions Development board demonstrates the possibilities of networking with embedded Microchip controllers over Ethernet and the Internet. As with any experimental system, however, some precautions needs to be taken before you start. Whenever new hardware or software is added to a network, it is always advisable to create a separate test network that is isolated from your LAN. This allows testing the new system in a controlled environment and minimizes the possibilities of network interference from the new equipment. Dr. Ece Yaprak 3

4 What is in the box The Development Kit contains the following items: 1. The PICDEM.net 2 Development Board 2. A standard serial cable (DB9, M/F connectors) 3. A standard CAT5 patch cord network cable for networking the board 4ACAT5 crossover 4. network cable for networking the board directly to a computer 5. The PICDEM.net 2 Development Kit CD- ROM Dr. Ece Yaprak 4

5 Using PICDEM.net2 with a Local Host System Although the PICDEM.net 2 Development Board is ready to communicate on a DHCP-enabled Ethernet network out of the box, you may have reasons not to do this. Besides those already mentioned, there may be others, such as: You don t have an Ethernet network available to experiment with Your network doesn t use DHCP and the Development Board must be configured with an IP address before it s allowed on the network Your network administrator forbids you to put the board on the network Dr. Ece Yaprak 5

6 Using PICDEM.net2 with a Local Host System For these reasons, the PICDEM.net 2 Development Board can also communicate directly with a properly configured desktop system, known here as a local host system. In this configuration, the host system can communicate and configure the board through its network connection; it can also configure the board through the serial port. When configured this way, the setup is referred to as a test system. Dr. Ece Yaprak 6

7 Using PICDEM.net2 with a Local Host System The Development Board can also communicate to a network and a local host system separately. In this setup, the board participates on the network through its Ethernet connection. At the same time, it is connected to the local host system through the serial port, from which it can be directly configured. Dr. Ece Yaprak 7

8 Dr. Ece Yaprak 8

9 PICDEM.net2 Development Board Features on the PICDEM.net 2 Development Board include: 1. MICROCONTROLLER: AMicrochipPIC18F97J60 microcontroller with built-in Ethernet controller and transceiver is directly installed on the board (U3). The device is clocked at 25 MHz and has been preprogrammed with the Demo Application firmware using the Microchip TCP/IP Stack. Jumpers, JP15 and JP3, can be used to measure the current consumption of the microcontroller. 2. ETHERNET CONTROLLER: In addition to the PIC18F97J60, the PICDEM.net 2 Development Board also features a Microchip ENC28J60 stand-alone Ethernet controller. This device provides Ethernet connectivity for microcontroller-based applications using a standard d SPI interface. Dr. Ece Yaprak 9

10 PICDEM.net2 Development Board 3. MEMORY: A Microchip 25LC256 serial EEPROM (U4) provides 256 Kbits (32 Kbytes) of storage for both web pages and nonvolatile configuration options. The 25LC256 is programmable via an SPI interface. 4. LCD DISPLAY: A two-line by 16-character dot matrix display shows diagnostic and error messages with the factory yprogrammed firmware. It may be used for other applications with appropriate reprogramming. Dr. Ece Yaprak 10

11 PICDEM.net2 Development Board 5. OPTIONAL EXTERNAL LCD CONNECTOR: Space is provided on the board for the installation of a 30-pin, bottom contact FFC edge connector (Hirose FH12-30S-0.5SH 0 or equivalent). This will allow the use of an external LCD character display module (such as one of the Optrex F series) to the board via a ribbon cable. Note that using an external LCD module will require appropriate changes to the application code, as well as the use of a ribbon cable compatible with the connector. 6. TEMPERATURE SENSOR: This analog temperature sensor, a Microchip TC1047 (U1), is connected to an analog I/O pin of the microcontroller. It can be disconnected by jumper. Dr. Ece Yaprak 11

12 PICDEM.net2 Development Board 7. USER-DEFINED LEDs: Eight LEDs are driven by digital I/O pins of the controller (PORTJ) and may be used to simulate a digital output to an embedded device. They may also be enabled or disabled by jumper selection on the board. 8. USER-DEFINED PUSH BUTTONS: These switches are connected to digital I/O pins on the microcontroller (PORTB<3:0>) and may be used to simulate a digital input in an embedded application. Dr. Ece Yaprak 12

13 PICDEM.net2 Development Board 9. USER-DEFINED POTENTIOMETER: One 10 kohm potentiometer is connected to an analog I/O pin of the microcontroller. It can be used to simulate an analog input in an embedded application. 10. RESET PUSH BUTTON: This switch is tied to the MCLR pin on the controller, and is used to reset the board. Dr. Ece Yaprak 13

14 PICDEM.net2 Development Board 11. RJ-45 (10Base-T) MODULAR CONNECTORS: The PICDEM.net 2 Development Board is outfitted with two Integrated Connector Modules (ICMs), one each for the PIC18F97J60 and ENC28J60. These ICMs provide the modular jack, as well as the necessary transformers, EMI suppression and status LEDs, for Ethernet connectivity. Each ICM has its own ACTIVITY and LINK LEDs on the left and right sides of the ICM, respectively (as viewed from the top). These show if an Ethernet application is transmitting or receiving a packet, and if the Ethernet connection is active. The LEDs for the PIC18F97J60 (on J1) can be disconnected by jumpers if the I/O ports, RA0 and RA1, are to be used for another purpose. Dr. Ece Yaprak 14

15 PICDEM.net2 Development Board 12. RJ-11 (Six-Wire) MODULAR CONNECTOR: This allows the Development Board to be connected to Microchip MPLAB ICD 2 systems for in-system programming, as well as advanced application debugging. 13. SERIAL PORT: The PICDEM.net 2 Development Board includes an RS-232 port with a DB9 connector (P1) and appropriate p level-shifting hardware (U5). This allows for the configuration of the board s IP and Ethernet address through a standard serial connection. This interface also allows users to download new web pages to the EEPROM. Dr. Ece Yaprak 15

16 PICDEM.net2 Development Board 14. I/O AND PICtail DAUGHTER BOARD ACCESS: A pair of female risers (J5 and J6) allow direct access to five of the microcontroller s I/O ports (PORTA through PORTE). The even pins of J5 also serve as a standard interface between the PICDEM.net 2 Development Board and any of Microchip s PICtail daughter board series. 15. PROTOTYPE AREA: A 9x20 grid with through-holes is provided for users to breadboard additional circuitry for development. Connections are provided for +3.3 VDC, +5 VDC, +9 VDC and ground. 16. ON-BOARD POWER: Two on-board regulators provide separate 5 VDC and 3.3 VDC at 500 ma common current, from the 9 VDC supplied at J POWER-ON ON LED: This LED (D9) shows the board is powered up. Dr. Ece Yaprak 16

17 PICDEM.net2 Development Board 18. ETHERNET ID STICKERS (TRACE SIDE): The numbers on the two stickers are used to form the unique Media Access Control (MAC) addresses used by the Ethernet transceivers to identify and filter packets. The number is the base10 version of the last 6 hexadecimal digits of the 12-digit MAC address. For example, the sticker number, 12345, represents h in the MAC address. One of these is assigned to the PIC18F97J60 and the other to the ENC28J60. These MAC addresses are provided for evaluation purposes; both addresses can be changed in software. Dr. Ece Yaprak 17

18 Microchip TCP/IP Stack pdf The Microchip TCP/IP (Transmission Control Protocol/Internet Protocol) Stack is a suite of programs that provides services to standard TCP/IP-based applications (HTTP Server, Mail Client, etc.), or can be used in a custom TCP/IP-based application. Dr. Ece Yaprak 18

19 Microchip TCP/IP Stack STACK ARCHITECTURE Many TCP/IP implementations follow a software architecture referred to as the TCP/IP Reference model. Software based on this model is divided into multiple layers, where layers are stacked on top of each other (thus the name TCP/IP Stack ) and each layer accesses services from one or more layers directly below it. Dr. Ece Yaprak 19

20 Microchip TCP/IP Stack STACK ARCHITECTURE A simple version of the TCP/IP Stack model is shown below Dr. Ece Yaprak 20

21 Microchip TCP/IP Stack STACK ARCHITECTURE The stack is written in the C programming language, intended for both Microchip C18 and Hi-Tech PICC 18 compilers. Depending on which is used, the source files automatically make the required changes. The Microchip TCP/IP Stack is designed to run on Microchip s PIC18 family of microcontrollers only. In addition, this particular implementation is specifically targeted to run on Microchip s PICDEM.netTM Internet/Ethernet demonstration board. However, it can be easily retargeted to any hardware equipped with a PIC18 microcontroller. Dr. Ece Yaprak 21

22 Connecting the PICDEM.net2 Development Board There are two basic network configurations for the PICDEM.net 2 Development Board: Direct connection to a network and connection to a local host system through a crossover cable. If DHCP is not enabled on the network, the board will need to be configured before a direct network connection can be used. If you are connecting the Development Board to a DHCP- enabled network, follow the steps in Section Connecting to a Network. Dr. Ece Yaprak 22

23 Connecting the PICDEM.net2 Development Board If you are using the board for the first time on a network using fixed IP addresses, follow the steps in Section Connecting Directly to a Host System. Once the IP address is configured the first time, you will be able to connect the board directly to the network as described in Section Connecting to a Network without using a local host. Dr. Ece Yaprak 23

24 Connecting the PICDEM.net2 Development Board If you are connecting the board to a local host in a test system configuration, you will also follow the steps in Section Connecting Directly to a Host System. If DHCP is enabled on the local host, the board will configure itself. Otherwise, you will need to configure both the host and board IP addresses according to the directions in Section 2.5 Configuring the PICDEM.net 2 Development Board. Dr. Ece Yaprak 24

25 Connecting the PICDEM.net2 Development Board All of this assumes that the Development Board is running the preprogrammed ddemo Application firmware. The general principles p for hardware discussed in the following sections still apply and may be used as a guideline. Dr. Ece Yaprak 25

26 Connecting the PICDEM.net2 Development Board Note: This section assumes that an Ethernet card has already been installed in the host system and is working properly, and that the TCP/IP protocol has been installed and bound to the card. If this has not been done, or if you are uncertain if this has been done, please contact your Information Systems support person for further assistance. Dr. Ece Yaprak 26

27 Connecting to a Network To set up the board for direct networking (Figure 2-1 from the User s Guide): 1. Connect the straight-through (patch) Ethernet cable to the board at Ethernet connector J1, then to the Ethernet network. This can be at a network port or an available port on a network device (such as a hub, switch or router). Note: Do NOT use the provided crossover cable if you are directly connecting the board to a network or network device. The crossover cable is intended only for connecting the board directly to a computer. Dr. Ece Yaprak 27

28 Dr. Ece Yaprak 28

29 Connecting to a Network 2. Apply power to the board (9 VDC) at J7. Note: The Development Kit does not include a power supply. If an external supply is needed, use Microchip part number AC Dr. Ece Yaprak 29

30 Connecting Directly to a Host System This option is used under the following situation: Evaluation of the Development Board as part of a test system; Operation on an isolated network is desired or; Connection to a deployed network is not possible. To set up the board for connection to a local host (Figure 2-2 from the User s Guide): Dr. Ece Yaprak 30

31 Dr. Ece Yaprak 31

32 Connecting Directly to a Host System 1. Unbox and unwrap the board, and set it on a nonconductive surface near the host computer. 2. Connect the serial cable (supplied in the kit) to the board, then to the available serial port on your computer. 3. Depending on the network connection to be used, do one of the following: For connections through an Ethernet hub or switch: Connect a standard Ethernet cable to the board, then to a port on the Ethernet device (Option A in Figure 2-2). The computer should already be connected to the hub or switch by a straight-through cable. Dr. Ece Yaprak 32

33 Connecting Directly to a Host System For direct connections to a host system: Connect the Ethernet crossover cable (supplied in the kit) to the board, then to the computer (Option B in Figure 2-2). 4. Apply power to the board (9 VDC) at J7. (See Section Connecting to a Network for power supply requirements.) Dr. Ece Yaprak 33

34 Confirming Operation Once the PICDEM.net 2 Development Board is properly connected and powered up, you should see all of the following: User LED D8 (tied to RJ0) is blinking User LEDs D1 through D7 are dark The green LINK LED on J1 is lit The LCD display shows the message: TCPStack v4.18 If the network uses DHCP, the display should change after a moment to: TCPStack v4.18?.?.?.? where?????.?.?.? is the board IP address as assigned by your network server. Dr. Ece Yaprak 34

35 Confirming Operation If your board does not show all of these things, check all connections with the power supply and the board. For additional assistance, refer to Chapter 5. Troubleshooting. If you are using a configuration with a local host system, power the system up now. If the board and/or local host require IP configuration, proceed to the next section. Otherwise, skip over to Section 2.6 Establishing Communications. Dr. Ece Yaprak 35

36 Test set up To accomplish the exercise requires the use of several development tools, such as, HyperTerminal for serial communication when assigning IP addresses programming EEPROM additionally DOS C> prompt environment for running Microchip File System (MPFS) utility to build Binary files of the multiple web page modules and lastly the MPLAB IDE AND ICD 2 Debugger used to program the microprocessor. Dr. Ece Yaprak 36

71 Loading the WebPage Occasionally, it may be necessary to reload the default webpage to the EEPROM memory. To do this, first launch your web browser with the Picdem.net 2 board connected via Ethernet cable. In the address bar of your web browser, type mchpboard/mpfsupload Dr. Ece Yaprak 71

72 Loading the WebPage You should see the following screen. Click Browse and navigate to C:\Microchip Solutions\ TCPIP Demo App\MPFSImg2.bin. Hit ok. Then click Upload. You should receive a message acknowledging the successful upload. Then type in mchpboard into the web browser s address bar. This completes this task. Dr. Ece Yaprak 72

73 Experimenting with Demo WebPage The Microchip Demo WebPage shows off the many features of the new Microchip 4.18 TCP/IP stack. These features utilize current and future web based technologies. We encourage you to experiment with these features. The features are as follow: 1. Dynamic Variables 2. HTML Form Processing 3. Authentication 4. Cookies 5. File Uploads 6. Gzip Compression 7. MPFS2 Uploads 8. SMTP server Dr. Ece Yaprak 73

74 Experimenting with Demo WebPage Dynamic Variable Substitution Consider dynamic variables the output of the application. This feature allows data such as system variables to be displayed within web pages. To create a dynamic variable, simply enclose the name of the variable inside a pair of tilde (~) characters within the web pages' HTML source code. (ex: ~myvariable~) The MPFS2 Utility will automatically index these variables in HTTPPrint.h, and will instruct your application to invoke the function HTTPPrint_myVariable when this string is encountered. For more information, see the Dynamic Variables page in the demo application. Dynamic variables also support parameters to be passed to your callback functions. Place the numeric value you want passed inside of parenthesis after the name of the variable. This value will be passed to your callback function as a WORD value. You can separate multiple values by a comma, but all variables of the same name must have the same number of parameters to function properly. If you have constants defined in your C code, those will also be parsed. Dr. Ece Yaprak 74

75 Experimenting with Demo WebPage HTML Form Processing HTML forms are the input to the application. This allows applications to process forms submitted via either the GET or POST methods. When data is submitted, the HTTPExecuteGet or HTTPExecutePost callbacks will be invoked. For more information, see the Form Processing page in the demo application. Authentication The Microchip HTTP2 server supports basic authentication. Applications can require a user name and password for access to any or all pages in an application. Multiple users and protected areas are supported, and all processing is handled d in the HTTPAuthenticate callback function. For more information, see the Authentication page in the demo application. Cookies By design, HTTP is a session-less and state-less protocol. User sessions can be tracked by setting and retrieving cookies in the user's browser. The Microchip HTTP2 server supports setting cookies, and data returned in a cookie is processed as a GET form argument. More elaborate authentication ti ti systems can be built using cookies, or they can be applied for many other purposes. For more information, see the Cookies Dr. page Ece Yaprak in the demo application. 75

76 Experimenting with Demo WebPage File Uploads Since the Microchip HTTP server supports POST requests, it can also process file uploads. This feature can be used to quickly load a batch of configuration settings into an application. An example of this functionality is provided on the File Uploads page in the demo application. GZIP Compression All modern web browsers can receive files encoded with GZIP compression. For static files (those without dynamic variables), this can decrease the amount of data transmitted by as much as 60%. The MPFS2 utility will automatically determine what files could benefit from GZIP compression, and will store the compressed file in the MPFS2 image when possible. This HTTP server will then seamlessly return this compressed file to the browser. Less non-volatile storage space will be required for the MPFS2 image, and faster transfers back to the client will result. No special configuration is required for this feature. Dr. Ece Yaprak 76

77 Experimenting with Demo WebPage MPFS2 Uploads When using EEPROM, MPFS2 BIN image files can be directly uploaded to the board using the web server. This eliminates the need for the FTP server, and therefore conserves two TCP sockets and about 1KB of Ethernet buffer RAM. To use this feature, access in a web browser (replacing mchpboard with the board's host name). The MPFS2 Utility accesses this feature internally to perform integrated uploads. This feature can be disabled for production devices if desired. Comment the macro for HTTP_MPFS2_UPLOAD in TCPIPConfig.h to turn it off entirely. Alternately, authentication can be used to require a user name and password to access this feature. Dr. Ece Yaprak 77

78 WebPage Experiment 2 For the first experiment, we will show how to store temporary data on the demo webpage by using cookies. First, on the demo webpage //mchpboard, click on cookies on the left side of the screen Dr. Ece Yaprak 78
