Web SD File Browser (Up/Download)

ripper121 · Post by **ripper121** » Tue Jul 30, 2019 12:42 am

Hi,
this is a little File Browser for the OdroidGo via the Webbrowser.

You can choose between Accespoint mode or connect to an existing Wifi:

The Web File Browser will create an Access Point with,
SSID: odroidgo
PSK: odroidgo
Webadress: http://192.168.4.1 (if you connected to the access point)

or

it will connect to the Wifi which was defined in the WIFI.TXT in the SD-Card root directory.
Webadress: http://displayedIPonOdroidGo or http://ordroidgo.local

WIFI.TXT

Code: Select all

MyWifiName
MyWifiPSK

there you can connect and browser the SD Card via a Webbrowser.
You can create folders, delete and upload new files.

That code belongs in a repository, not code blocks

Also, there's no fw file...

ripper121 · Post by **ripper121** » Tue Jul 30, 2019 9:29 pm

First release in Git and with FW file

joshua.yang · Post by **joshua.yang** » Wed Jul 31, 2019 10:08 am

Great. A portable NAS?

ducalex · Post by **ducalex** » Wed Jul 31, 2019 12:19 pm

Very cool! I would suggest adding station(client) mode support, it's a bit annoying to have to open wifi settings on my phone/computer to connect to the odroid, and then back to my regular wifi every time.

ripper121 · Post by **ripper121** » Wed Jul 31, 2019 3:30 pm

Ok will do a Station version also

ripper121 · Post by **ripper121** » Wed Jul 31, 2019 4:39 pm

Update:
- added Wifi Station mode
- some little fixes

Download: https://github.com/ripper121/odroidgowe ... Browser.fw

Nemo1984 · Post by **Nemo1984** » Wed Jul 31, 2019 11:51 pm

This is great! I really like it! Now I can add games and firmwares on my Odroid Go from my phone!

Makromolekuel · Post by **Makromolekuel** » Mon Sep 02, 2019 1:07 am

I tried to compile the sketch but getting an error.
Is it necessary to change something at the standard installation?

ripper121 · Post by **ripper121** » Mon Sep 02, 2019 1:32 am

Without the error I can't help you.
Can you compile the odroidgo examples for arudino (like the hello world or button sample)?

Makromolekuel · Post by **Makromolekuel** » Mon Sep 02, 2019 3:10 am

The examples compile all without any errors.

ripper121 · Post by **ripper121** » Mon Sep 02, 2019 5:39 am

Again without any error info we can't help you.

Makromolekuel · Post by **Makromolekuel** » Mon Sep 02, 2019 3:42 pm

Attached you can find the error protocol.
Thanks for your help.

ripper121 · Post by **ripper121** » Mon Sep 02, 2019 3:47 pm

Please delete the Web folder in "C\YourUser\Documents\Arduino\libraries\ODROID-GO\"

Makromolekuel · Post by **Makromolekuel** » Mon Sep 02, 2019 4:33 pm

Thanks for the quick answer.

After deleting the folder the sketch compiles without any error.

Makromolekuel · Post by **Makromolekuel** » Mon Sep 02, 2019 8:53 pm

After being able to compile without errors I now get an error when starting the app on the Odroid Go.
I always get "Card mount failed". It's the same with the prebuild FW or my own compilation.
My SD card is fat formatted.
Any advice? Thanks.

ripper121 · Post by **ripper121** » Mon Sep 02, 2019 9:01 pm

repower after flashing (remove USB cable if connected and then repower the device)

Makromolekuel · Post by **Makromolekuel** » Mon Sep 02, 2019 9:16 pm

Even after repowering I get the error:

Initializing SD card...
Card Mount Failed

ripper121 · Post by **ripper121** » Mon Sep 02, 2019 9:18 pm

Then try another card.

Makromolekuel · Post by **Makromolekuel** » Mon Sep 02, 2019 10:14 pm

I tried another card and now it works
Thanks again for the help.
