I have LM3S6965 ethernet learner kit. Iam not sure whether this ethernet learner kit will support Microc osii. Iam new to this LM3S6965. I dont kno how to proceed....iam searching for tcp/ip for cortex m3. In the user manual of this kit, it s mentioned that it supports freertos..can anyone help me in working with this LM3S6965....i like to work with microc osii..how to prgrm,how to work with tcp/ip ???? how to send data thro ethernet of this controller?????
What kit, exactly, do you have?
If it's a "learner" kit then, presumably, it must come with explanatory documents, examples, etc for you to study?
"Iam not sure whether this ethernet learner kit will support Microc osii"
Why does that matter?
Do you mean this: micrium.com/.../os-ii ?
What does their documentation tell you about the requirements for µC/OS-II ? Does the board meet those requirements?
Do you have any experience with µC/OS-II ?
"Iam new to this LM3S6965"
Do you have any experience with any other microcontroller(s)?
Do you have any other programming experience?
"I dont kno how to proceed"
Why not start with the materials included in your "learner" kit?
"iam searching for tcp/ip for cortex m3"
TI provide several TCP/IP examples using the uIP and LwIP stacks - have you looked at them?
"can anyone help me in working with this LM3S6965"
You need to start by putting in some study of your own.
If you're new to microcontrollers and/or programming, then TCP/IP is not the place to start
"i like to work with microc osii"
Any particular reason?
"how to work with tcp/ip ?"
Do you understand how TCP/IP works in general? If not, that's the first thing you need to study!
"how to send data thro ethernet of this controller?"
Look at TI's examples.
You seem to have a tendency to start lots of threads, but not follow-through:

As noted on the TI thread,
"you should resolve your difficulties with SPI programming before moving on to Ethernet programming. The latter requires more skills"
If you couldn't manage SPI on a processor that you say you are "used to", it seems a bit of a leap to try TCP/IP and Ethernet on a totally unfamiliar chip!!
Actually my project is on sensor interfacing to a controller and then performing some simple processing like switching off the relay, alarm etc based on the data from sensor module. Then all the data from controller has to be sent to a pc and iam supposed to maintain a webserver. This is my project. I started with ARM LPC2148. I used micro c osii and completed sensor module..i could see the output in hyperterminal for uart program in which task will get the status of adc and display the cuurent value frm adc. Now iam supposed to send the data thro ethernet to a pc.For that i need an external ethernet controller. I planned to buy enc28j60 where i require to write spi code....But i dont have any idea about how to write spi code,what al files to include and how to proceed..so i thought to buy serial to ethernet converter which do not require any special coding...and data can be sent thro uart itself!!
And now al of a sudden, i got LM3S6965 ethernet kit with keil tools (Texas).Idont kno wat to do!!!!!!!!! i tried the sample prgrms given with this kit....No RTOS prgrms are given... i downloaded freertos code and compiled then tried to fuse it in to the kit, so many errors!!!!it s mentioning mismatch!!!!! Iam familiar with microc osii than freertos.i hav nil knowledge abt freertos....i hav worked with microc osii (..like simple codes) Now really i dont kno what to do!!!!!!!!!!! i really wanted to learn things and complete my project successfully...but i really dont kno how to proceed....................... Mr.Andy any suggestion???? can yo just guide me....please.....Also time left to complete my project is also less... its abt hardly 1 and half month to finish my project!!!!!!!!!!!!!!!!!!!!!!
"And now al of a sudden, i got LM3S6965 ethernet kit with keil tools"
Pardon?? What do you mean, "all of a sudden"?
These things don't just magically appear - they have to be ordered and paid for.
"Mr.Andy any suggestion?"
Sorry, but the only thing I can suggest is that you are in way over your head; you need to go and be honest with your teacher and admit that you have no idea how to complete this assignment.
Then you can discuss with your teacher how you can catch up with the learning necessary for a task like this.
i got that kit from my friend......this only i meant as al of a sudden
I agree. TCP/IP stacks on microcontrollers do require considerable skills. As I said elsewhere, the fact that SPI programming poses difficulties is very telling. How can anyone hope to put together an MCU-based web server before clearing the hurdle of SPI programming?
