Hi every body, I am in a bit trouble of finding out the processing time taken by main_tcpnet() function. As it is written in documents that this function must be called periodically but does not specify at how much rate i.e milliseconds. Secondaly since i have other work to do also during interrupt (timer) i wonder how to fix main_tcpnet() function in the same interrupt as doing this causes my hardware to reset. Plz help me Thanx in advance
Hello friends, Long time no see, Ok i am in the way of completing my project as i called main_tcpnet() from the while(1) loop. Now in my way i am suffering from hurdles as i asked earlier. My latest hurdle is as follows:
1) I have made 200 servers on LPC2300. A client (can be more then 1) will ask for running data from these servers.
2) I have allocated different IP address to each (Please suggest me a way to dynamically allocate these addresses)
3) Main hurdle is to allocate MAC addresses to each servers, Since the adresses are allocated by IEEE then what should i do to allocate it.
Please suggest me a way
Why not register with IANA?
What i have understood from surfing is as follows:
1) Hitex has purchased OUI (organization unique identifier) which is of three Most significant bytes which is 00-30-6C
2) Rest of the three bytes are empty
3) We have to apply for extension identifier that is assigned by the IEEE Registration Authority and then reserving an additional 12 bits for use by the assignee. The resulting 48-bit identifier uniquely identifies the assignee of the IAB and provides 4096 unique EUI-48 numbers for use by the organization that purchased the IAB.
Example of EUI-48 created within an IAB:
An EUI-48 identifier is formed by combining the 36-bit IEEE assigned IAB base value with a 12-bit extension identifier assigned by the organization â€" e.g., if the IEEE assigned IAB base value is FF-FF-FF-FF-F0-00 and the 12-bit extension identifier is hhh16, then the EUI-48 value generated by combining these two numbers is FF-FF-FF-FF-Fh-hh
