Hi

I have a OLIMEX PIC-WEB which has a 18F452 + enc28j60 and also has a AT45DB011 1Mbit SPI flash memory.

I got example 15 (A webserver that accepts GET and POST commands) working and I now have a basic understanding of what is happening in the code, I can modify the contents of the page etc.

The question is how can I store the html page in the flash memory and have the PIC read from there?
The PIC program memory can not store big web pages.

Any suggestions?

Thanks!

If you look in the TCPIP source directory, you'll see something called MPFS support.

(Mine is located in: C:\Program Files\PICC\TCP-IP\PIC Examples Source\mpfs)

It allows compressing the webpages into a single file which can then be stored on an external memory like a FLASH or EEPROM.

Read up on it and it'll all make sense to you.

Cheers,

-Ben

Thanks for the tip, I will check it.

But what about the driver for the flash memory?
Both the memory and the enc28j60 are on the same SPI bus and I do not want to interfere with it.
Maybe at the time I use the SPI bus the pic wants to send/read to the enc28j60.
