Thank you for your reply, so mine RX pin isn't damaged! 

Hello everyone,

The + lead of my 6 AA batteryholder with 6 AA NiMH batteries in it (a total voltage of 7.2 V) accidently has be connected to my Arduino' s Digital pin 0 (the RX Serial pin) . Is it damaged now? I didn't connect the - lead to the Arduino Board.

Kind Regards,

Superpelican 

I get same error on my Lubuntu 10.10 installation and also v.21!

It seems to be a problem with the new USB chip. RX (Receive), TX (Transmit) are Serial pins. Earlier the Arduino team also had problems with the RXTX. That was in v.20 when there was no version for Linux avaible. In v.21 the problems had to be fixed. May be the fix didn't have impact on your installation .

(I use Lubuntu 10.10, the LXDE version of Ubuntu, http://lubuntu.net/)

I hope you now understand the things a bit more,

Superpelican

Thanks, I thought I had AVR GCC installed. I'm gone a try to install AVR GCC again.

Thanks, for the help,

Superpelican

[edit]I checked AVR GCC = installed. It has to be an other problem...
 
[/edit][edit]I reinstalled the AVR GCC, the situation don't changes. The error shows some files in the Arduino IDE software folder. I found the files in the software folder. That means that al those"expected:...." are not in the examples or my programs, but in the Arduino IDE files!
Hope that people now have more info about my problem,

Hello, everbody I am new at this forum. Today I received a Arduino Uno. I use Lubuntu Linux. I tried to upload  both my own program and the LED blink example. Both times I get this error:

I don't have any experience with Arduino or electronics. Is this just a IDE error?

Thanks, for any help,

Superpelican

Yes, I already heard that when you feed your Arduino with a 9V they don't last long. But it is only until I have a 6 AA holder.

Thanks,

Superpelican  

So I also can power my Arduino with a 9V battery+clip instead of the 6 AA the same way? Without blowing my Arduino of course!
,

Superpelican  

So, @smeezekitty, I can safely power my Arduino with my 6 AA  batteryholder, wich delivers 7.2 V (as I am going to use 1.2 V NiMH rechargeable batteries)?

Thanks for all the help everyone,

Superpelican  

So, that means that the Powerpins are connected to the Voltage Regulator, so I won't damage my Arduino?

Hello, everybody

Can I use the VIN and GND powerpins on my Arduino Uno to power my Arduino (with a 6 AA batteryholder)? Otherwise I'll have to buy a 2.1x5.5 mm powerplug and solder this to my batteryholder.

Thanks for any help,

Superpelican  

So, you mean that I'm now running my Dfrobot LCD Keypad shield on 4bit with the Liquid Crystal library as well? With the customization ,mentioned in the topic I linked to in my older post, of course!

Thanks, Superpelican  

Hello,

I got my Dfrobot LCD keypad shield working with the Liquid Crystal library thanks to a little change in Hello World! example from the Arduino team. I found the solution in this topic: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1275941693/12,

Superpelican  

Sorry, but I can't find a "Hello World!" example in your link  

Googling also doesn't seem to help. But if there doesn't exists a Dfrobot- 4bit-library example, would someone like to help me with making one?
I don't want to use the buttons, because they're terrible hard to program for. I want the LCD display to just display some text, like the original Hello World example written for the HD44780-Liquid Crystal library.

Hello, does someone now a good "Hello World!" example for the Dfrobot LCD keypad shield, wich uses the LCD_4bit_mod library. I'm a real newbie and can't make one myself. They say the 4bit display is easy and doesn't uses much resources (pins). But in my opinion it's not so easy as they say.

If there doesn't exists one would someone like to be so kind to make one?

Thanks for any help,

Superpelican
