Any chance my libraries could be added under the contributed libraries section of the Wiki?
Change Notification [url]https://sourceforge.net/projects/chipkitcn[/url]
I'd add it myself but it's a closed wiki :(

Can you give me a description to put in the wiki page as well?
They have been added here:

Can you give me a description to put in the wiki page as well? Jacob
Network Fully object oriented IP stack, currently supporting the ENC28J60 chip, but can be expanded to support other interface chips and methods. Multiple concurrent sockets, connections and chips supported.
GLCD Double buffered graphical LCD library for the KS0108 and similar 128x64 LCD displays.
Change Notification Access the Change Notification pins as standard interrupts with attachInterrupt() and detachInterrupt(). Supports RISING, FALLING and CHANGE. Also has the ability to attach different interrupts to different edges.
RTCC Real-Time Clock & Calendar. Access the internal RTCC of the PIC32 chips using a simple object interface. Can also drive an interrupt when alarms occur.

@majenko What version of MPIDE does your network library support? I'm having trouble getting it to compile, with error:
In file included from C:\Users\Chrissy\OLD Dropbox\mpide-0023-windows-20120429-test\.\hardware\pic32\libraries\Network/Network.h:34:0, from WebServer.cpp:2: c:\users\chrissy\old dropbox\mpide-0023-windows-20120429-test\hardware\pic32\compiler\pic32-tools\bin\../lib/gcc/pic32mx/4.5.1/../../../../pic32mx/include/sys/endian.h:54:22: fatal error: sys/swap.h: No such file or directory compilation terminated.
I've tried other version (all windows based) to no avail:\
Thanks in advance for any assistance.

I have the same error either with Network-r5.zip or Network-r7.zip using Linux MPIDE :
/home/martin/mpide-0023-linux-20120903/hardware/pic32/compiler/pic32-tools/bin/../lib/gcc/pic32mx/4.5.1/../../../../pic32mx/include/sys/endian.h:54:22: fatal error: sys/swap.h: No such file or directory
Could you explain how to fix that ?
Thanks in advance,

Attached is a copy of the missing swap.h file. Drop it into the sys directory as shown in the error message. We lost this file when we moved to the Newlib libc instead of the proprietary MIPS libc. Sorry for the inconvenience, we will see about getting it added back into the mpide distribution.

I worked around it by using my own htons() et al, but thanks for that.

If I understand, this missing file is should have been part of MPIDE. Thanks for the attachment, but unfortunately, although it get further, it lead to another error :
/home/martin/mpide-0023-linux-20120903/hardware/pic32/compiler/pic32-tools/bin/../lib/gcc/pic32mx/4.5.1/../../../../pic32mx/include/sys/endian.h:100:1: error: 'u_int32_t' does not name a type
Is there any plan for a new MPIDE release soon ?

Anything from Network-r7 and up has removed the dependency on endian.h (and thus swap.h). If you still see this error with r7 or r8 then there must be something else that is including endian.h as a requirement of its own - something not under my control.
If that is the case, you might try including <sys/types.h> first before anything else.

Thanks a lot ! I got it : there was another copy of R5 sitting in my library folder ... Now, it compiles fine.
Fri, 14 Dec 2012 15:10:44 +0000
That fixed my problem. Thank you!

Hi again Majenko,
I got your WebServer example working fine. I decided to start my own with a method that should stream a file located on a SD card. It worked fine if the file is quite small, but it seems that only the first block is transmitted when the file is bigger, probably the first TCP_BUF_SIZE. I've tried to insert a "c->flush()" on every 2000 bytes in my streaming loop, but no chance, only the first 4800 bytes seems to be transmitted, although the streaming loop continue to do its "c->print()" until the end of file.
Do you have any clues to make sure the whole streaming reach the client ?
Thanks in advance, Martin.

The print routine (utility/tcp.cpp) is supposed to queue the output in a circular buffer until it reaches the "mss" size (1440 bytes), at which point it should dispatch a packet. The same happens with flush(), it just forces the despatching of a packet with whatever is in the circular buffer.
The circular buffer code was pretty much lifted verbatim from the circular buffer of the HardwareSerial.
Unfortunately I don't have anything set up at the moment for testing, but if you can do a little testing for me that'd be great.
Can you confirm if the packets are actually not being sent, or if they are corrupted in some way? Maybe using some network sniffing software (I use tcpdump under linux) to see if there are packets arriving that are in fact being rejected, and maybe why, that'd be fantastic.

Thanks for the hints. The packets are actually transmitted, but for some reasons, the client probably reject some, I'm not very fluent with tcpdump. The client(s) are actually browsers, Firefox on Ubuntu, Firefox on Windows or IE, they all stopping showing the file, a JPG from the SD card, after few pixel's rows, only 1/10 of the picture shows up. But tcpdump shows that the remaining are actually transmitted. I've then tried a different image, same thing occurred, although the amounts of good pixels aren't the same between images, but they are across browsers for the same image. Also, I've discovered that after several "getfile", I have to reset the Max32 since it doesn't responding to any urls.
