CC3200 Filesystem (SD and Flash)

Hans Zimmer

Other Parts Discussed in Thread: CC3200

Currently we are designing a data logger with cc3200. Therfore we made a file system on an sd card to store our logged data. Now, we want to get this filesystem on a website. So we want to post those files to the website on which we can download the files to our pc. Is there an example of this? Or anybody has worked on this too?

In a second step we want to Post some look up tables from the website to the external flash (please look my other post: http://e2e.ti.com/support/wireless_connectivity/f/968/t/402455)

How is this working? Which library should i use and are there any examples?

Thanks a lot and best regards!

Hans,

Downloading a file using a web browser can be done if you use CC3200 file system (i.e. if the file is stored on the serial flash). You can look at the following E2E post: http://e2e.ti.com/support/wireless_connectivity/f/968/t/400566

If you implement your own file system (e.g. on an SD card), the internal HTTP server is not aware of the files as it is not the file system it directly uses.

Hi
So if I want to download some files from SD card, I could copy them from SD to SFlash, right? Is this possible?

Thanks

yes, you can. It would need to go through the host MCU.

And is there a API for this? So I can copy a file directly from SD to SFlash? Or do I have to read the content on SD and write it to a new file in SFlash? I'm sorry that I ask all these things, but its the first time I work with this :S

Thanks

Unfortunatelly, you would have to read it from SD card and write it to the serial flash. There is no other way.

Alright, thank you.
Another question: I created a file on the sflash with the demo application file_operation. I named it "www/log.txt". If I implement it in my webserver, I can access the file with mysimplelink.net/log.txt, right? And how can I download it? I want to press a button which opens a save as dialog.

Best regards

Yes, you can test it by writing such file to SFLASH and type from your browser its URL.

Regarding implementing it via a button, it is HTML design which I'm not expert on so I cannot assist.
