Hi everybody,

 

http://duinoserver.codeplex.com/ is a ready to use webserver, which enables you a full file management on your SD card. It sets the local time via NTP after starting, supports UDP discovery and implements a simple, easy extendable Json-handler for led status requests and switching the led state.

So with a browser you can browse all directories and download every single file. Much more comfortable is using http://duinoexplorer.codeplex.com/ (or http://duinofinder.codeplex.com/ on MacOS). With that tool you can up- and download files and directories (and mixed with multiselection), rename or delete them in a Windows Explorer (iOS Finder) likely style. It also supports UDP discovery and contains a Json editor for sending and receiving Json commands.

 

How all this looks like:

 WS_explore.png   70.22KB   124 downloads

 

 WS_discovery.png   26.86KB   93 downloads

 

 WS_led_js.png   34.02KB   73 downloads

 

 WS_blink.png   32.29KB   59 downloads

 

I want to share this with the community and hope, someone finds it usefull. I appreciate every kind of response.

Ah, the world's first Netduino NAS - very nice work!

 

About the Duinoexplorer - is that a fully custom made application or does it somehow integrate with windows?

 

What transfer speed can you reach when downloading a reasonably large file?

 

Does it support uploads too?

 

If you put a second SD card in there, you could have software RAID too

Thank you.

 Is it really the first one?

It is fully self made (the C# standard libs, like Windows.Forms and System.Net.WebClient are used, but I think it's not what you meaned?

in DuinoFinder I used the same code, but the GUI (there I took Gtk instead of Windows.Forms, what is also for Unix available))

 

 

What transfer speed can you reach when downloading a reasonably large file?

There the Netduino is the speed determinant. My device (N+2) sends and receives with ~ 40 - 45 kB/s, but I haven't made detailed analyses yet. It is maybe a good idea for further investigations and optimations.

Sorry, I don't know, I haven't made any investigations in that direction yet. My devices have only a single slot for SD card. Is there an extra hardware necessary?

...Is it really the first one?

As a web server I think not but as Networked Attached Storage, I suppose it is. In a data acquisition application you don't have to take the card out to examine the log which ought to be an appreciated feature.

I was thinking more in terms of whether you can access the files as kind of a network share like SAMBA (or something like that) using the standard Windows Explorer. I get that impression from looking at your pictures.

I didn't mean that seriously but yes, you would need an external SD card slot and drive that over SPI.

No, all file and folder accesses are made by http - commands (GET, PUT, DELETE), except renaming. That is realized with (non http, but WebDAV) MOVE and is implemented to have a really full file management (but probably only supported in DuinoExplorer an DuinoFinder on the client site).

A multi users access authorisation is not implemented yet.

I see. What are you using this for yourself?

Later that Json part shall be strongly enlarged. Commands and actions will be executed via json. And for that I can store ready to use js-files, additional data, images ... in a comfortable way and without installing another program or taking off the SD card. Then all actions can be triggered from any device in my local network (tablett, smartphone).

My second intention is learning by doing - it is my first Netduino project.

It's smashing project. I've tried it with my upgraded N+1 (4.2) with a success. But I've failed to do it with my N+2.... it's seems couldn't even deploy.. and finally error come up. Tilos may I know which firmware u use on your N+2 board.. thanks..

sorry for not answering until yet, I haven't been on this site for a while.

My N+2 runs with firmware 4.2.2.2 and works well. I can recompile and deploying without any problem.

But I must say I tried before with 2 different N+1 (4.2) and with one everything worked well, but with the otherone I only had problems. Even deploying the new firmware was big trouble and took many attempts (and time) and the responce varied. So I guess there was a hardware problem and I gave it back. Maybe it's something like that? Does on your N+1 DuinoServer works, or are there any problems?
