ENC28J60 compiler problems

[cruzxia]

I am just trying to setup and use the ENC28J60 component for the first time, but I am having a few compiling problems.

If I use Bens WebserverwithpingECIO it compiles, If I change the micro to PIC18F2455 it compiles ok.
If I start a new project using PIC18F2455 and try to Initialise the ENC28J60 component, it fails to compile.
I have checked the compiler and linker settings and they are identical.

Here is the error
Test_Code.c(190): error: total number of array elements can not exceed 0x100 (use -idx 2 compiler command line argument to remove this restriction)

I added "-idx 2" to the compiler and linker but it still had an error.

Has the ENC28J60 component been updated or modified?

Check the ENC28J60 component properties to make sure arrays/buffers contain max 255 elements. The BoostC compiler limits array sizes.

Thanks for that, it is compiling now.

didn't know that V6 had this component now , does it work with this module ?

does it work with this module ?

Yes, it should work with that module.

I have the ENC28J60 connected and working. I am using a Pic 1825K20 @ 16mhz with hardware SPI.
It will respond to the ping in about 3ms.
When I type in the IP address In the browser, it does not receive the webpage data from the webserver (FILLTcpDATA).
I just get - "This page can’t be displayed"

I have tried using software spi - same results
I bumped my clock speed to 64mhz with the PLL, I had to then slow the SPI down to Fosc/16 to get it running in hardware, no change
I then tried it in software mode at 64mhz with the SPI Fosc/4, no change.

Any suggestions on how to get it to respond.

Please post your flowchart.

I use the LCD for a few Debug markers. When I try to access the IP in my browser, the code make it to the reply (marker "4") but there is no data on the web page.
The ping looks like this.

I managed to get the 8 bit pic sort of working, it would reply with half the webpage data. Having read the forum I decided to move to a 16 bit pic to try to get it working.

I setup the component using a DSPic33EP64MC206, because I had one from another project.
The SPI ports for channel 1 did not match the actual ports on the pic so I used channel 2 and remapped the ports to the ones I selected.
The SPI is now working, I can initialise the ENCJ60 and control the LED's, read the version etc.


The compiler did give me a whole heap of warnings relating to the ENC28J60 component.
Do I need to rectify some of these warnings?

Here are the compiler warnings.

I have encountered a problem in the example software that I am having trouble getting passed.

The Readstringfrombuffer only ever seems to return "GET"

When it tests for data with this

Compare$ (CompareString,"/page2.htm",0) = 0

there is no data (other than GET) in the comparestring so it wont go to Page 2 or to the Root Page in the example software.
I can only ever display Page X

Please advise what is wrong?

[cruzxia]

I found the problem.
The CompareString=TCPIP_ENC28J60::ReadStringFromBuffer(DataPointer, 10)
must be changed to
CompareString=TCPIP_ENC28J60::ReadStringFromBuffer(DataPointer + 4, 10)
To read from the correct buffer
