| TCP-IP stack, how to? |

Hi, I'm planning to make a project which involves connecting a PIC to a remote location via WWW.
So the TCP-IP stack will be used.
Microchip is releasing new revisions of their C18 stack, i'd like to use them into CCS.
Have someone already ported the C18 stack by himself?
Can you confirm that the last CCS ported stack is version 3.02? |

The last stack converted by CCS was 3.75.
The latest Stack from MCHP is 5.1. It has not been "CCS-ized"...
Using the stack requires the usual required learning according to code size. I think I got the stack up and running in a day or two so that I could use it on a PICdem.net2. From there playing with the webserver was immediate.

Looking the examples it's simple to play with, but porting surely is a big work. I'd like to know the reason CCS don't port the stack anymore. As said before it's a huge work but having it usable with their compiler would be a nice feature no?  |
The last stack CCS made available was 3.75.
From Microchip, 5.1 is the current version available. I'm working on "porting" it for a client.
I heard a rumor that CCS is making efforts to make 5.1 PIC-C friendly without a lot of re-work.
This would allow MCHP to release whatever and it would compile readily under CCS without the headaches.
It sounds like time better spent.

Pardon but I'm making confusion with version numbers...
You mean that CCS C compiler version 5.1 will 'eat' Microchip stack -as is- or that CCS is porting microchip stack v. 5.1?
I think/hope the first hypothesis, it would be very nice! At this point just one question remains: when? |
Not a problem.
Current version of CCS is 4.099. This includes PCM, PCB, PCH PCD... (according to my version information)
The Current version of the CCS compilable TCP/IP stack is microchip's v3.75 that CCS "fixed" to make PIC-C friendly.
If you go to Microchip's website and download their latest TCP/IP stack, that version is 5.1.
It does not compile with PIC-C "out of the box".
CCS can do one of two things:
1. Port MCHP TCPIP 5.1 to compile with PIC-C.
2. Change PIC-C so that MCHP's TCPIP will compile "out of the box".
#1 is not a long term solution.
#2 is long term solution.
My understanding is that #2 is the present course of action.
