The official Arduino thread

maevius · 2011-08-24 23:06:53

So, I'm opening this topic to discuss about our favorite hardware platform. There is a wiki page to get you started [1], and of course there is the arduino-sdk in aur [2]. Feel free to talk about both the harware and software part.

I just realised this is more suitable for the Programming forum. Can someone move it there?

When reading the wiki page, I noticed the following:

I can not remember loading neither cdc-acm nor ftdi_sio. Is the module loading part of the "Installation" section still required?
I would directly link to the "arduino" package in AUR instead of a search with the keyword "arduino", as I recommend installing arduino instead of arduino-syslibs.
Is the "Running arduino for the first time" section still needed? I never ran into the problem described there, but I also never used the Two Wire Interface. If the problem still exists, I will try to add the .o-file to the package.
Multiple parts of the page recommend to edit the preferences.txt manually. Imho, the settings should be changed using the GUI.
I will merge the changes described in "Associate .pde files with the Arduino IDE" into the arduino package.

maevius · 2011-08-26 08:54:38

Grab a cup of coffee and read on! Here are my findings
I tried to install arduino in my desktop x86_64 in order to test your points, and that's what I came up with.

Arduino loads fine without cdc-acm and ftdi_sio. I don't know whether they are needed afterwards though.
+1 to link to arduino package in AUR. I'm on it.
I don't know about the Two Wired interface problem you describe. If that happens only on rare occasions and is not a universal problem, I say we move that to Troubleshooting section.
+1 about the removal of manual editing of preferences.txt. First time I installed arduino, I followed the wiki by the book so I don't really know which parts are redundant.
Cool.

Also I faced a problem with java. It might be a rare occasion but it would be ok if we added this to troubleshooting.
When I tried to run arduino as root I got this

No protocol specified
Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using ':0' as the value of the DISPLAY variable.

Anyway, I solved it following this guy's instructions.

Now, regarding the gcc-avr-4.6.1-1 that causes compilation errors, we have two solutions.

Either use this to patch arduino-headers.
Or install gcc-avr-svn which is confirmed to work.

I tested gcc-avr-svn but the same error occurs unfortunately... I applied the patch and compilation works without issue with latest gcc-avr/svn.
Could you try the svn solution to check if the problem came back so that we report it?

I just tried gcc-avr-svn (revision 178132) and was able to build a sketch successfully.
I also tried the patch and gcc-avr 4.6.1, which worked as well.
Compiling the digital_potentiometer example of the Wire library also succeeded (without running arduino as root), so I will move the twi.o section to Troubleshooting.

Could someone with an arduino please try if the modules (cdc-acm and ftdi_sio) are loaded automatically when the arduino is connected? (The output of lsmod before and after connecting the arduino would all I need to know)

I will try to release arduino-0022-6 this evening. It will include the progmem-patch (because it is easier to include the patch then to have every user install gcc-avr-svn) and will allow to pass arguments to the arduino executable.

SidK · 2011-08-27 14:32:15

I have an Arduino. My modules line in rc.conf is empty and just rebooted.
I did not start the IDE, just did an lsmod, then plugged the board in (USB) and did an lsmod again. cdc-acm and ftdi_sio appear in neither listing.

Edit: just to make it clearer, the changes in those listings are:

diff before after 
1a2
> cdc_acm                13412  0 
30c31
< usbcore               119644  4 usbhid,uhci_hcd,ehci_hcd
---
> usbcore               119644  5 cdc_acm,usbhid,uhci_hcd,ehci_hcd

Much later edit: I'm blind, cdc-acm is listed. the IDE successfully uploads with an empty modules line and no manual module loading.

@SidK: Great, then I will remove the instructions to load the modules manually from the wiki page.

I also just released arduino-0022-6:

uploaded 0022-6:
* includes patch for compatibility with the current (broken) gcc-avr 4.6.1
* allows to pass the sketch to open as a command line argument to /usr/bin/arduino
* reminds you to add yourself to the uucp group

Cilph · 2011-09-08 18:25:55

It might be a good idea to use the AVR plugin for Eclipse as the Arduino IDE is just horrible. I tinker with AVRs as a hobby and I just use the plain chips on a breadboard without the Arduino libraries. Main reason is that because they make stuff so ridiculously easy to use, it even takes 20 cycles to write a single output to a port.

If you want you can still import the Arduino libraries and use them anyway.

I'm using the AUR arduino package and still getting errors when I try to compile. From what I've been able to tell this package *should* fix the gcc-avr bug, but I get the exact same error.

Furthermore, I thought 4.6.1-1, the latest version of gcc-avr, was supposed to be fixed to begin with? Is this true?

I'm trying to compile the reprap Sprinter firmware found here (https://github.com/kliment/Sprinter) for an arduino mega 2560. I am reasonably sure the code is not bugged - I was able to compile it on windows fine, and hundreds of people worldwide use this same code.

I have tried downloading the IDE from the arduino site, I've tried the AUR IDE package, and I've tried compiling the gcc-avr-svn package from the AUR. I get the same error every time. WTF am I doing wrong?

The error I get is the following:
SdFile.cpp: In static member function 'static uint8_t SdFile::make83Name(const char*, uint8_t*)':
SdFile.cpp:259:17: error: variable '__c' must be const in order to be put into read-only section by means of '__attribute__((progmem))'

maevius · 2011-12-26 18:31:47

With the latest arduino 1.0, the menu list isn't shown. Does anyone else have this?

Edit: That seems to be a problem of X, I have the same issue on v.022.

Now in v.1 I can't write in the ide. The keyboard doesn't work. I'll try in desktop too. These issues are seen on my netbook.

I have this problem as well, on two different laptops. For a while I used the scons build system from cli, but today (with an arduino update) it started complaining about 'build/core/pins_arduino.h' being missing. I hear this is due to housekeeping by the devs, and have yet to find a readily available fix for either of these problems.

mandos · 2012-06-12 12:09:55

I've been using the arduino software in my system for a long time. Lately I did a re-installation of arch. I believe that I managed to communicate with it on my new system.

Then I updated to arduino 1.0.1. Since then I cannot select a serial port as a user.
I can as root.

I am in the uucp group however, and I can send data to the port from the command line (echo) as a user.
I've been trying to solve this for two days now. I'm officially stuck on this!

maevius · 2012-06-13 06:53:19

There is an arduino-git package in aur [1], did you try that?

[1] https://aur.archlinux.org/packages.php?ID=57079

mandos · 2012-06-13 09:06:00

I tried this solution by tirezo:

I had the same exact problem, I was able to fix it by changing the permissions of the lock folder. Try:
sudo chmod 777 /run/lock
and see if it fixes your problem

and it worked. He wrote it last night here https://aur.archlinux.org/packages.php?ID=8388

haven't tried the git version of the package yet

lesto · 2012-06-15 17:36:34

I have to use chmod every reboot!! every times it return to default value!

Make sure you are a member of the uucp-group and that uucp is the group who owns the Arduino-device.

lesto · 2012-06-19 23:27:37

dunz0r, can you expands you explanation? how i set the owner of arduino devices, with UDEV rule?

Problem -
When I upload to my Arduino on my x86_64, it gives me this error - avrdude: stk500_recv(): programmer is not responding
Any suggestions?
I've googled this quite a few times, but they were not relevant to my issue.

That error doesn't really mean anything --- it just says that the uploader program (avrdude) couldn't find a programmer.

Did you change the port in the tools->Port list? What board do you have?

The board should show up as /dev/ttyACM0 if you have an uno/recent mega, or /dev/ttyUSB0 if you have an older version. Make sure you have read/write permission to it.

Hm.

I set it to /dev/ttyACM0 and the board is the Arduino UNO R3.

And I don't know, when I did in the wiki the stty thing, when I ran cat (all of them as sudo), it did not work. I added myself to uucp and I readded root to uucp. Nothing worked.

Also, it did show up as /dev/ttyACM0 (as stated before), and I really don't know how I can make it have read/write permisson.

EDIT: I am now trying to uninstall arduino, and install arduino-git. Let's see how this will work.
EDIT: Again, nothing. It's giving me the exact same issue.

bump for help, read previous post

Technicolor · 2012-10-02 13:01:09

Fixed.
Evidently the arduino package from the AUR with the "patched librxtx package" does not work without rxtx (not lib) from the AUR.
