Network connections and data transfer with tiva-c

Nicolas Demonty

Hello,

I already posted some posts to get info about how doing a telnet server or tftp client. However I never got any clue how to achieve this. As the info I found and as all examples are not documented I don't even see how to start.

My project is like a frequency analyzer. I would like to convert an analog signal with the ADC, then do a Fourier Transform and send the result to a computer through the ethernet connection. I m able to do the ADC and FFT but I really don't see how to send data (1 file wit all result or displaying the result via a telnet prompt for example). All example I found in CCS or on the web are not documented. Apparently I'm not the only guy looking for such info in this forum but no post does provide a clear example.

I also found some info about RTOS. Do you think I should go in that direction or has anyone a concrete working example of a telnet or tftp application ? Please give me a hint, I m totally lost ...

thanks in advance

Hello Nicolas

Why a telnet or tftp program to transfer the data. Can't a UDP packet with a custom protocol work? To what end device/system do you plan to send the data to?

Actually I would like to interact with the board. I would like to open a prompt from a computer through the Ethernet connection with putty for example. Then I would like to interact with the board via a menu that the board will provide (launch the application, stop it, display info and results). I also would like to send data in a files fox example.

The issue is that I don't find how to start. Each similar post doesn't provide any concrete example.

Hello Nicolas

Do you mean something on a line of an IoT device but with command prompt?

Yes a kind of. I need to connect on the device and retrieve the result on the screen or in a file. Everything in real time.

So where can I find a concrete and documented code which I can base my application on.

Thx

Hello Nicolas

Then why not use the qs_iot example which connects with Exosite Cloud server

Will have a look if meets my needs especially for the interaction aspect

Thx

Hello again. The example sounds good except that it behaves like a client which initiates the connection. It is interesting in the way it provides how to sends data but don't you have any example or hint how to configure the board as a telnet server ?

Hello Nicolas

No, I do not have an example nor is there any in TivaWare or collateral that I am aware of.
