Heb je de library DCF77 gedownload en op de juiste plaats gezet?
Indien wel kan je de library DCF77 toevoegen via de arduino ide; indien niet is dat je probleem.

Als de library goed geinsalleerd is kijk dan eens in de file DCF77.h
daar moet iets staan als
class XXX
struct XXX
en vervang de lijn
DCF77 myDCF=DCF77(DCF77Pin);

I think they are really close (at least if you have a the latest version of both)
What I know what arduino did is
1) adding functionality that is needed because you are no longer talking about a hacked device but a preinstalled version. (for instance the web site to connect to a wifi AP)
2) Selecting existing packages to make it all work. Like avr dude, php, sd card, bonjour .....
3) adding the bridge functionality
4) adding specific arduino commands/packages (like reset wifi that resets the wifi when wifi can not connect or reset-mcu )
5) Wrap it all up in a nice "package"

Best regards

That will be lots quicker and easier

I can hardly imagine this question has not been asked before but I don't find anything. So here I go:

Can I reset the leonardo with a command from the linino? I currently reupload the sketch but there must be better ways to do so.

Best regards

Thanks @sonnyyu.

Do you know where I might find instructions for installing them, or for finding the versions that work on the Yun?

surf to the yun
log on
clcik configure
click advanced configuration panel
select system->software
click update list
type what you are looking for in the field filter and click find package
Click on the packages you want to install.

Best regards

There is also the arduino eclipse ide which support (officially) all boards supported by arduino IDE and the whole Teensy Family.
Many people use it to program other boards.
You can download version V2.2 which works best with arduino IDE 1.5.2 and play at

I'm really trying to find out if I should spend money on a Yun just out of curiosity. If it is really only practical as a Wifi webserver for programs running on the Arduino side I don't think I will bother.

I guess it all depends on what you want to run extra.
You simply cannot compare the memory usage and footprint of you linux with the linino. This because the linino code is written with the size limitation in mind.
Basically you can run any -non gui- program (as long as you do not run out of memory) but it will take longer.
I think the yun excells in mobile aplications. This because you have the wifi and a linux all in one allowing you to have the robot wireless from day one with the confort of arduino as you are used to.
I would prefer a mega yun for robots though as the leonardo is limited in memory and program space and pins. ( @ arduino core team: hint hint hint  smiley-grin )
For my robot I plan to use a yun and a arduino mega. I'll connect the arduino over usb to the linino. This works perfectly but I still have some minor issues to do the switch).
Note that some people attach a web cam to the linino.
So I think the linino is not only a wifi to a leonardo.
However I don't know where it stops.
Maybe someone can help you out by connecting his yun to the internet and allowing you to have a play with it.

I am a Windows user, so I use Putty to connect but there are similar programs for Unix.
I'm on unix and I use putty as well.

Linino = openwrt.
openwrt = Linux without GUI
Linino has quite some memory and storage.
Some differences I'm aware of (after using openwrt for 2 years)
Bash = ash
ash is similar to Bash but has less functionality. However I never found anything that didn't work for me or had an acceptable alternative.
Storage is flash so as erni says avoid writing to much. /tmp is a memory drive so you can write as much as you want there.
The SD card is auto mounted on /mnt/sda1 (yes automount works)
As you know linux is a collection of packages. Openwrt has as little packages as possible. Linino has far more packages by default and lots of room to add packages.

As to programming. You can use the toolchain that is used to build linino to make packages and install them on linino. I would call that advanced programming.
You can use any of these scripting languages to program "out  of the box": php, ash, bash, lua (and probably more)
The static web site is located at /www and the dynamic web site is at /www/cgi-bin.
A word on LUA from nick gammon

To me the most important thing is that you do not have a gui on linino and it is very likely you will add packages when stepping outside the standard arduino usage.

BTW, do you know someone official from the Arduino Team that would be able to address this above concern?

I wish I know. Federico Fissore from team time to time post here and hope he will address this issue.
Why not ask Massimo himself?;u=13

Ok, so were are the schematics and layout for the Hornet (AR9331) MOST important parts?

Where are the schematics and layout in editable format? smiley-mr-green
I'm concerned with Arduino being open or not.
I on the other hand don't understand the importance of AR9331 being open. Are the AVR chips open? I guess not (I really don't know)
For me Arduino is open if they tell you which components they use and how they are being used. It does not mean they have to use all open components (I assume they never did)

Or am I missing something?

Why not sign up for an account with an ISP?
I use these guys for my fencing club,, very inexpensive.
I use to upload files via ftp.
mine is at which starts at 1.25 euro a month for 5Gig (cheaper than startlogic). I recently upgraded to 30GB for 2.60euro/month to host the nightly builds. before that I don't think I ever hit 3Gig so there is room.

418  Products / Arduino Yún / Re: Using Serial and Bridge at the same time on: February 06, 2014, 04:17:50 pm
I have my serial port connected to linino and use serial and bridge at the same time.
I guess if you have a USB to ttl converter you can simply use serial as you did before.

Hi Duane
I'm quite willing to let you use my server to store data. But if it is about open source code why not use github?
That gives you version control and not hassle with third parties for free (github is free for open source projects)
There are quite a lot of Arduino libraries on Github The Arduino code is on github so is my arduino eclipse plugin (and the lib I made from your rc code  smiley-grin ).

for instance the rc lib can be found here and if you want to link to the code you can to

But if you prefer not to. I have room  on smiley-grin
Best regards
420  Using Arduino / Programming Questions / Re: How to find out what is to big (for both data and program) on: February 05, 2014, 12:42:29 pm
I found a good reference.... the AVR data sheet. More specific the AVR CPU core chapter and the AVR ATMega61U4/ATmega32U4 Memories section.
Now I understand the relation between memory allocation and source code I've been able to drop below the 32K again :-)

Program:   32356 bytes (98.7% Full)
(.text + .data + .bootloader)

Data:       2467 bytes (96.4% Full)
(.data + .bss + .noinit)

Thanks for all the input.

PS I finally understand why PROGMEM is a good thing. For those who don't I'll explain
When having a standard char[]="blabla" he is in the .data section and .data is counted in both Program and Data.
If you use char[]PROGMEM="blabla" the load will move from .data to .text. This makes no difference for program but it does decrease the Data size.
