Merhaba
ben web üzerinden mikrodenetleyici kontrol etmek istiyorum. buna ait örenk çalışma yapan arakadaşalr var. özellikle html dosayası kodları ve mikrodenetleyici kodlarıyla beraber verebilriseniz sevinirim. yardımcı olursanız sevinirim.
Hocam hoş geldiniz. ;D
Bu konuyla ilgili açtığım konulardan ve yaklaşık 1 yıldır ara ara yaptığım çalışmalardan edindiğim tecrübeyle cevap vereyim. Bulabileceğiniz en kolay yol mikroC nin içindeki örnek kod.
Eğer içinden çıkabilirseniz Türkçe bir kaynak olarak size Barış SAMANCI'nın yazdığı kendi ekitabına bakın. Ben içinden çıkamadım. Ama bu sizinde anlayabilenlerden olma ihtimalinizi yok etmez dimi..
mikroC nin örnek programı aşağıda. Microchip stackı kullanacak olursanız inanın çok daha karışık, Yada ben daha basit olanı bulamadım...
Bu kodu mutlaka mikroC ile derlemeniz gerektiğini hatırlatmak isterim.
saygılar...
edit : kodun uzunluğu sizi korkutmasın, neredeyse yarısından fazlası açıklama satırları....

* Project Name:
enc28j60Demo (Ethernet Library demo for ENC28J60 mcu)
* Target Platform:
PIC
* Copyright:
(c) mikroElektronika, 2006.
* Revision History:
20060810:
- Initial release. Author: Bruno Gavand.
*
* V1.0 : first release
* V1.1 : bad MIME type for / path request, changed to HTML instead of SCRIPT (thanks Srdjan !)
*
* description :
* this code shows how to use the Spi_Ethernet 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 main page
* all other requests return also HTML main page
*
* target devices :
* any PIC with integrated SPI and more than 4 Kb ROM memory
* 32 to 40 MHz clock is recommended to get from 8 to 10 Mhz SPI clock,
* otherwise PIC should be clocked by ENC clock output due to ENC silicon bug in SPI hardware
* if you try lower PIC clock speed, don't be surprised if the board hang or miss some requests !
*
* EP settings :
* RA2 & RA3 pots jumper : closed
* PORTA : pull-down (place jumper J1 to lower position) (board specific)
* PORTB : pull-down (place jumper J2 to lower position) (board specific)
* PORTC : pull-up (place jumper J3 to upper position) (board specific)
* BUTTONS : pull-up (place jumper J17 to upper position) (board specific)
*
* mE Serial Ethernet board on PORTC
* RC0 : !RESET to ENC reset input pin
* RC1 : !CS to ENC chip select input pin
* the ENC28J60 SPI bus CLK, SO, SI must be connected to the corresponding SPI pins of the PIC
* the INT and WOL signals from the ENC are not used *
* Test configuration:
MCU: PIC18F4520
http://ww1.microchip.com/downloads/en/DeviceDoc/39631E.pdf
Dev.Board: EasyPIC6
http://www.mikroe.com/en/tools/easypic6/
Oscillator: HS-PLL4, 08.000MHz
Ext. Modules: mE Serial Ethernet board
http://www.mikroe.com/en/tools/serialeth/
SW: mikroC PRO for PIC
http://www.mikroe.com/en/compilers/mikroc/pro/pic/
* NOTES:
- Since the ENC28J60 doesn't support auto-negotiation, full-duplex mode is
not compatible with most switches/routers. If a dedicated network is used
where the duplex of the remote node can be manually configured, you may
change this configuration. Otherwise, half duplex should always be used.
- External power supply should be used due to Serial Ethernet Board power consumption.

microchip stackleri çıkalı bi kaç sene oldu sanırım. ve 18f ailesi ve üstü desteği var.
peki ccs c nin böyle bir kolaylığı var mı? ya da bu konuda yazılmış kütüphane falan? var mı duyan?
web kontrol için .net dillerinden biri ile arayüz programı yazarsınız, bu program verileri internetten çeker, pic kısmı kesinlikle değişmez, usb veya rs232 kullnabilirsiniz.
hocam ben bu iş üzerine ugraşıyorum ve en kolay yol adres satrından veri göndermek ve veri tabanına yazmak ve verileri diger bir sayfadan çekmektir yine veri tabanından online olarak kontrol de biraz sıkıntı çıkabilir fakat 5 saniye yada 10 saniye gibi zaman dilimlerinde veri tabanına girip verileri tekrar okuyup degişiklikleri picte yada veri tabanında gerçekleştirebilirsin bu söylediklerim DİREK ETHERNET baglantıyla degil gsm modül kullanıyorum internete baglanmak için uygulaman için basit gsm modüller kullanabilirsin. kolay gelsin.
