program a router in microCfor PIC 16f887

[zemzela]

program the PIC to work as a Super Router, and reading the serial
port frame, forwards them to the standard, or rejected. The next message
format:

1. Destination MAC, 6 bytes fixed - variable value for each frame
2. TTL, 1 byte fixed - variable value for each frame
3.Length,1 byte fixed - variable value for each frame
4. Data, [1, 16] bytes - variable value, variable length for each frame
5. Error Code, 1 byte fixed - sum of all units in the field 1-4

And process the PIC as follows:
First Checking the MAC address.
- If it is rejected and the LCD display reads in two lines - "Receive
frame which is not for me ".
- If it is addressed, go to step 2

Second Checking the Error Code.
- If the frame is error, rejecting the LCD screen and write in two rows -
"Receive frame which is error".
- If the frame is not an error, go to step 3

Third Check the TTL.
- If the TTL is 0, the frame is discarded and the LCD display reads in two rows -
"Receive frame TTL = 0".
- If TTL> 0, go to step 4.

Hi, its great to see you visiting our forum. Why not try Proton Compiler for FREE? Download the FREE version of Proton Compiler, Its called Amicus18 and its available from HERE Already using proton Compiler??? Get rid of these pesky messages... get LICENSED USER STATUS

4th Creating a framework for sending.
- In the Dest. MAC value is entered as DestMac own arbitrary will
create it as a variable
- TTL field is reduced by 1 from the received frame
- Length field remains the same
- Data remains the same field
- Calculate new value for the Error Code field

After creating the frame, it sends the serial port, and write the first row of the LCD
- "Receive frame:", second row area Data

After sending, wait for a new framework. Assume that in the meantime not to arrive
new framework.

Any ideas how to solve this problem, It is very important for me, please help me...

Post up all the the PROTON BASIC code you have written so far and we will see what we can do

This seems more like a request for HOW to DO IT rather than a project.
Tim, you poo-pooed the tcpip stack post, and quite rightly imho - but this is similar but on under the counter steroids !!!!! JEEEZ ! - a router, by it's very nature, would be TCP-IP input and output on Layer 3 , after reference to layer 2, of the OSI ref model, MAC addressing would be Layer 2, Routing would be lay 3 - I would freeking platt sawdust and dance naked in Walmart's window if anyone wrote a 'super router' on an 8 bit pic !!..
AND it would need a full dedicated TCPIP stack, and also the above mentioned layer integration and control .... forget it !

My main point was that he is looking for code in MicroC and he probably posted the same request on every pic forum out there.

Agreed, another dumb single digit IQ uni student wanting someone to write his thesis with no actual understanding of ANY of the issues,
If what you say is correct, and I do agree, then it is bordering on spam... oh well.. ... life goes on... either a Walter Mitty or a Jack Sparrow, or possibly Walter Sparrow lol

Indeed he is all over Google trying to locate a source code. He has nothing to offer or a legit user of PDS.
