Maybe you could give YUN a static IP in your LAN, then if you have your lan made with openwrt, you could add a package that would use dynamic dns services to give your online IP a name in the internet that would follow your changing IP.. Then there's the security issue- you could install VPN server and this way it should work..

A lot of work and reading, but can be done..

I also have custom software written in C that I'd like to include in my YUN..

Been there for awhile now for OpenWRT community, so I do know how to create packages when building new firmware, but I've always though that it's a great system if you have something that is ready.. It takes gigabytes of your harddrive and hours until firmware image is ready and package compilation begin, before all this, support systems, like toolchain is being built..

Yes, that's the official way.. But was just thinking if development on Yun would had been made simpler.. There once was a full gcc package available for openwrt as well, but no more- as they want to avoid native compiling for good reasons, but when making small changes, something similar would really speed up things while developing, after all, we don't all run linux here..

I would say that it is IPEX antenna connector, you need adapter like this: http://www.ebay.co.uk/itm/IPEX-to-SMA-Antenna-24cm-for-Mini-PCI-E-Wireless-WiFi-Card-RF-SMA-to-IPEX-U-FL-/261014214409?pt=US_Directional_Network_Antennas&hash=item3cc5a8d709

btw. before ordering, find one for you, adapters are available for all existing standards, SMA, RP-SMA, etc..

And if you want to add support for not currently by openwrt supported device- check out gentoo's ebuilds, most of them are relatively easy to concert to openwrt packages..

If Linux drivers exists- this should not be a problem as linino is heavily based on openwrt, a long time ago I added support for ms laptop webcam on my openwrt driven linksys nslu2.. Then made a script that took a picture and export it to web- so when ever I opened that page, it took a picture and displayed it on my browser. Also added auto update on that page later, so it streamed with 1fps..

And this was not hard- so if the kernel drivers are there, it's not that hard..

Just ordered a Yun-- and a USB-TTL 3.3v/5v convertor based on PL2303HX..

You  just keep talking about jtag camera.. I have 3 of these: http://www.adafruit.com/products/613
Might be that you found something better, but since I've already invested to these it's unlikely that I go the other way..
But because of the curiosity.. I might wanna have a look at the cameras you found too.. Got a url to your findings..?

But I have a serial ttl jpeg camera for arduino.

i suggest you to add an hub to Yun to have 4 usb ports, plugging a usb-serial in one of these to interface the jtag camera. This you you could have constant streaming in and enough power to decode the jpeg on a full libraries machine!

Another way would be to store data to sd card

this way is easy, you just put the final jpeg image into a file, and invoke "cp file /mnt/sd-somewhere/somewhere"


Actually, this might be a solution.. Didn't understood what you meant first, since you talked about jtag camera instead of serial jpeg camera.. If I don't add more devices- why a hub? For powering up? Camera is powered up by different power lines..

Thanks for answers- it seems it's a no go then..

Adding a hub and another kind of camera is not a good idea- I already bought 3 of these cameras, they have IR leds for night vision and packaging for outside use, so they weren't so cheap that I would give up on 'em too easily..

I thought using arduino YUN would make my system easier, but it seems I'm stuck using Maple Leafs for this (or I could use Arduino Due, it has 3 USARTs.. but maple's do the job, don't need so much space + are way cheaper..)..

And SoftwareSerial can handle 38400 atleast on UNO, but it doesn't matter, when I open up another software serial, for e.g. to send data over rs485, connection to camera is disconnected.
9  Products / Arduino Yún / Bridge and a constant serial link.. on: September 12, 2013, 04:57:56 am
Can I use bridge to transmit data between arduino and Linux while constantly keeping a serial open to another device? Using 2 serial devices with arduino Uno wasn't possible - when another serial was opened, previous port closed.

Where is this needed? Well, I can think numerous reasons, for example; hacking and forwarding serial data from another device- possibly parsing it.. But I have a serial ttl jpeg camera for arduino. (From adafruit) and even though jpeg data is very compact when comparing to raw image data, amount of bytes in a 320x240 jpeg image- is too much for arduino to store/process atk once. Idea is that you freeze the camera, and download it's view in jpeg format in blocks, store/process the block and download next block, until full file is received - now here's the problem. If serial link is interrupted, camera needs mee initialization before you can download a block, another problem is- initialization resets camera, so you cannot resume image downloading process. I'd like to make my own wifi camera, and with arduino yun - that is going to be easy- but only if serial link isn't interrupted while transmitting data to Linux side.

Another way would be to store data to sd card, but I was not sure if provided sd is connected to arduino side or to Linux side- also, this would slow things down if you first store image data to sd and then open file from there and send it to Linux side.

And one more thing- what is the baudrate used on the bridge and can it be manipulated? Camera uses 38400, it would be nice to have fast communication with the bridge as downloading a 320x240 jpeg with 38400 and storing as blocks to sd takes about 3 seconds..
10  Products / Arduino Due / Re: [Finally a working EMAC library] Connecting an Ethernet PHY to Arduino Due on: July 25, 2013, 01:44:45 pm
Took a look at it.  This hardware kit can't be used simultaneously with your CTE LCD shields. Bummer.  Split decision... lots of wires for the LCD or lots of wires for the Ethernet.  Oh well. The DUE platform will get there eventually.

Ehm.. What does this mean? Arduino Due cannot have SD+TFT+Touch+ethernet - or does this just mean that shields are incompatible if they are not being wired? I am interested in a project that has a tft with touch.. And Sd.. And would be connected with ethernet.. Currently I have a shield from aqualed source for 5.0" tft - and was thinking I could use a ribbon cable to take ethernet connection "outside" - but does this then work or not?

12  Products / Arduino Due / Re: Arduino due DS1307 RTC library on: March 16, 2013, 03:52:25 pm
And here's even better..

I've combined Henning Karlsen's library with RTClib and fixed day of week calculation as well. Library does not require wire.h and works just like RTClib except, you can set alternative sda and scl pins if you like.
Library is available here: https://github.com/oskarirauta/RTCdue

I have problems accessing DS1307(rtc) on pins 20(sda) and 21(scl). RTC renders un usable right after initializing UTFT.. :/

Any help appreciated..
15  Products / Arduino Due / Re: SdFat for Due posted on: March 15, 2013, 09:35:59 pm
Thanks!

Nice library - I've combined it and RTClib, as I think RTClib was better expect it was using Wire.h and I'd rather go without..

Anyway, my bad and my apologies - it seems after all not to be SdFat that causes this, it's UTFT which makes sure RTC is in accessible.. Investigating further..
