How to access data from TIVA to local data format like csv(excel) or other format?

Hi All,

I m using TIVA C series board TM4C1294XL for current project. i could get to display the data from the uart port to Teraterm using serial communication. Now, next is to display that data with GUI at HTML level. for that as per my current  understanding , i need to keep my data somewhere( much better if local) and HTML page will access data linked to those rows and columns. my current data is hang 3 columns and 19 Rows. and the data is refreshed at rate of 1 secs in tera term. and i want to show it in the same way at HTML.

I got some suggestion to get data in CSV format and then do the html coding. and the second suggestion is to use MySQL to store data. but still i dont understand how can i copy the data from the microcontroller registers to some file or some server.

Please help me here.

And so sorry to community members, in rush, I asked this question in wireless connectivity, not a suitable forum for this question.

Thank you so Much!

    Hello Sachin,

    Did you check the ethernet web server example (enet_io) in which TM4C hosts a web page. Considerable work on the html aspect would need to be done to get it in a format of columns and rows but that would be possible.

    Does not your post's "body" steer (hard & long) "away" from its "title?"   That confounds assistance - does it not?

    You move on to, "Copying data from the MCU "Registers" to some file..."    Would it not prove far more effective to copy such data from the MCU's RAM - which greatly outnumbers the Registers - and where such data proves far more, "persistent?"

    There exist commercial products which enable the direct loading of "raw data" - received via the PC's serial port (usually) - directly into "Excel!" 

    Now anything you do "live" (@ the MCU during (one suspects) Data ACQ) tends to slow the rate and reduce the size of your, "MCU data capture."   Thus - to my mind - such is better handled @ the PC.

    The data stored w/in MCU RAM - to my best knowledge - is not stored in any (normal) Excel compatible format.   Thus our group simply routes that data to the PC - for "post processing" and then presents (that) data directly to Excel.

    It would seem possible to employ a fast, external MCU (or cluster of MCUs) to receive this ram data - and "massage" it into CSV format.

    Absent any (usual) performance specifications - further guidance reduces to guesswork...
