... Connecting and testing the board The PIC-WEB comes with a default code and web server that you can test in a couple of simple steps. First of all you have to configure the Ethernet port to be able to work on your local network. That is possible trough the MCHPStack Configuration Console. ...

Page 17

... File->Properties->Settings->ASCII Setup. Then save the connection for later use. After this setup the connection with the PIC-WEB should be ready, but the console will not show anything!. That’s because the board is not running on configuration mode. To run on that mode you just need to push the “ ...

... DHCP to get the configuration from your router. The first and the second options are not used in this manual. At this moment we will only use the on-board default page. The last option saves the configuration and restarts the PIC-WEB. For testing purposes you can connect the board directly to your computer with a crossover ethernet cable , configure the board with 192 ...

Page 19

... Test WEB page was mentioned above, the PIC-WEB board has an embedded web server and a demo page. The page shows some of the features of the board and it have a link to Olimex’s PIC-WEB information page. To access the demonstration page, the server must be accessible from the computer. The default IP address of the board is 192 ...

... BUT, the value of the potentiometer, the status of the LED and so on. To toggle the status LED of the board (PIC-WEB) you can click on the green dot under the caption “LEDs:”. By clicking on this dot you are changing the state of the pin, see how the led switch on or switch off ...

Page 21

... At the page you can also see some values of the PIC-WEB sensors and buttons: • Buttons: • Potentiometer: • Temperature: “Potentiometer” shows a measurement from the PIC A/D connected to a 10KΩ potentiometer on the board, you can freely change that potentiometer position and check how the measurement changes. “ ...

... TCP/IP protocols included in the Microchip Stack. In this manual we will explain how to create a dynamic web page, but this isn’t the limit of the PIC-WEB and the TCP/IP Stack, you can get further to reach the full capacity of this platform and manage other protocols of network communication between the PIC microcontroller and any client or server in the network ...

Page 25

... You can upload programs to the PIC-WEB with any programmer and software compatible with PIC18 like Olimex’s PIC-ICD2-POCKET programmer. MPLAB Integrated Development Environment MPLAB IDE is free software distributed by Microchip that includes a toolset for development of PIC microcontroller applications for windows OS ...

Page 26

... There are several ways to program a PIC, but the easiest and proper way to program the PIC- WEB is using a compatible programmer with an ISCP connector and compatible with MPLAB IDE. For this purpose it will be used an USB programmer compatible with MPLAB ICD 2 sold by Olimex, the PIC-ICD2-POCKET. ...

Before compiling check that the necessary include directories are well configured to use C18, those are: • Include Search Path: MCC18\h • Library Search Path: MCC18\lib • Linker-Script Search Path: MCC18\lib Page29 ...

Page 30

Now is time to compile! If there aren’t bad configuration the compilation must be successful, that means that you have to get the “BUILD SUCCEEDED” message on the output window. Note: the version of the MPLAB IDE that you are ...

... After you have load this “*.hex” file, you should open .\PIC_WEB_RevB_Patch\pre- built\Microchip Ethernet Discoverer.exe. Click on the button “Discover Devices” and the IP address of PIC-WEB will be discovered (for example - 192.168.0.238). Note that your LAN has to have DHCP server. In your browser type the IP of the board with the following path: http://192 ...

Page 32

... Click on the button “Choose File” to select the “*.bin” file you are about to upload. Select the image file in directory .\PIC_WEB_RevB_Patch\pre-built\MPFSImg2.bin and press 'Upload'. Sit back and relax while the upload takes place and then navigate to the home page to behold the page just uploaded. Now your PIC-WEB is with Olimex's original software. Page32 ...
