السلام عليكم
وجدت هذا الكتاب لعله ينفعكم
وأنشاء الصفحات النت بدايه تهيئه لغرض ربط مايكروكنترولر بشبكه الانترنيت بأستخدام مكتبه sp_eathernet او wifi
http://up.top4top.net/downloadf-top4...ec5e1-pdf.html
وياريت من أي شخص لديه معلومات يضيفها لغرض نتعلم معا كيف نربط مايكرو بشبكه الانترنيت من شرح الكود او الاوامر او أي شيئ يساعدنا كلنا في تعلم هذا موضوع بشكل اوسع

* Project name:
ETH_click (Demonstration of mikroBUS ETH click board)
* Copyright:
(c) Mikroelektronika, 2011.
* Revision History:
20071210:
- initial release; Author: Bruno Gavand.
20071210:
- modified for PRO compilers (FJ).
20111215:
- modified for ETH click board (DA);
* Description:
this code shows how to use the ENC28J60 mini library :
the board will reply to ARP & ICMP echo requests
the board will reply to UDP requests on any port :
returns the request in upper char with a header made of remote host IP & port number
the board will reply to HTTP requests on port 80, GET method with pathnames:
/ will return the HTML main page
/s will return board status as text string
/t0 ... /t7 will toggle RD0 to RD7 bit and return HTML
* EP7 settings :
AN0 potentiometer jumper (J15)
PORTB : pull-down (PortB three-state switch) (board specific)
Jumper (J17) in Vcc position
the INT and WOL signals from the ENC are not used
* Test configuration:
MCU: PIC18F45K22
http://ww1.microchip.com/downloads/en/DeviceDoc/41412D.pdf
dev.board: EasyPIC7
http://www.mikroe.com/eng/products/view/757/easypic-v7-development-system/
Oscillator: HS-PLL 32.0000 MHz, 8.0000 MHz Crystal
SW: mikroC PRO for PIC
http://www.mikroe.com/eng/products/view/7/mikroc-pro-for-pic/
ext. modules: ETH click ac:ETH_click
http://www.mikroe.com/eng/products/view/794/eth-click/
* NOTES:
- ETH click board with ETHERNET controller ENC24J60 is placed to the mikroBUS socket 1.
Program uses SPI1 perpheral to comunicate with ETHERNET controller.
LED RB0 will always be ON since it is connected to INT pin of ENC24J60.
