After having followed the steps.. I just keep getting 

/dino/lib/dino/tx_rx/usb_serial.rb:17:in `io': Dino::BoardNotFound (Dino::BoardNotFound)

If you don't mind saying how you solved it?

nishantmodak commented 11 years ago

I had to run the program as a 'root' user. The user I was running with was not authorized to create serial connection. (Linux)

austinbv commented 11 years ago

ah good to know for anyone in the future

vishaltelangre commented 10 years ago

@nishantmodak Tried to run the file as root user, I'm still not able to get rid of the error!

vickash commented 10 years ago

@vishaltelangre What version of dino and what operating system? Can you post the backtrace you get?

vishaltelangre commented 10 years ago

@vickash: This is the backtrace of the error that I am getting:

austinbv commented 10 years ago

Do you know what device your arduino mounts to?

vishaltelangre commented 10 years ago

Well, I think it must be FTDI driver, here is the dmesg's output:

And, I did confirmed that the ttyUSB5 was the needed serial port, but Dino didn't recognised it though.

Sorry I forgot to respond to this. Which board are you using? Also, have you tried using the master branch (0.11.3)? The handshake routine was too aggressive in 0.11.2, since I wrote it using only an Uno for testing. It should be much better in 0.11.3.

ensaaj commented 9 years ago

I am using Dino 0.11.2 and test an Arduino Uno on Ubuntu 12.04. Just started learning this very interesting Ruby language and tried the jumpstartlab excellent tutoriol. When the baudrate from the default value given by the tutoriol (115200).. everything work fine eventhough the same warnings are given,, but the terminal and arduno board indicate both are communication. But when change to 9600 baudrate the same warnings appear but ardunio and Ruby does not work.. Hope this helps

regards Aziz

vickash commented 9 years ago

Have you changed the baud rate in the sketch and re-flashed the board? Both the board and the ruby script need to use the same baud rate.

ensaaj commented 9 years ago

Dear Mr Vickash

Yup.. I change the baudrate in du.ino ( using Arduino IDE 1.0.1) from 115200 to 9600(not working) and flash the modified sketch to the arduino board. I cannot find baudrate setting for blink.rb. I only change the baudrate for the serial port and arduino sketch..

vickash commented 9 years ago

Initializing the board (and TxRx) should look something like this if you have to set baud to 9600:

board = Dino::Board.new(Dino::TxRx::Serial.new(baud: 9600)

Try that and see if it works.

ensaaj commented 9 years ago

Dear Mr Viskash

Do i have to add require 'serialport' ?.. and additional close bracket. When I change the baudrate to the serial port, du.ino sketch and blink.rb , the board and ruby is no loger talking and i have the following messages

/home/toshiba/.rvm/gems/ruby-2.1.1/gems/dino-0.11.2/lib/dino/tx_rx/base.rb:43: warning: ambiguous first argument; put parentheses or even spaces /home/toshiba/.rvm/gems/ruby-2.1.1/gems/dino-0.11.2/lib/dino/tx_rx/serial.rb:40: warning: ambiguous first argument; put parentheses or even spaces /home/toshiba/.rvm/gems/ruby-2.1.1/gems/dino-0.11.2/lib/dino/board.rb:99: warning: ambiguous first argument; put parentheses or even spaces /home/toshiba/.rvm/gems/ruby-2.1.1/gems/dino-0.11.2/lib/dino/tx_rx/base.rb:52:in handshake': Dino::BoardNotFound (Dino::BoardNotFound) from /home/toshiba/.rvm/gems/ruby-2.1.1/gems/dino-0.11.2/lib/dino/tx_rx/serial.rb:23:inhandshake' from /home/toshiba/.rvm/gems/ruby-2.1.1/gems/dino-0.11.2/lib/dino/board.rb:13:in handshake' from /home/toshiba/.rvm/gems/ruby-2.1.1/gems/dino-0.11.2/lib/dino/board.rb:9:ininitialize' from dino.rb:9:in new' from dino.rb:9:in

'

If I change back the baudrate 115200 to all setting.. work fine (after remove the require 'serialport' (make mistake i think).. I might like to change different baudrate higher that 9600 ..I havent sleep for 24 hours learningg Ruby!!

ensaaj commented 9 years ago

Dear Mr Vickash

The program works at baudrate 38400 , 57600.. I guess it will also works at higher baudrate Anyway.. I thank you very much for helping me

vickash commented 9 years ago

Sorry. There was a mistake in my code above. Forgot a ")" at the end.

It should be:

board = Dino::Board.new(Dino::TxRx::Serial.new(baud: 9600))

If you got it to work at higher rates, I guess you figured that out eventually.

Another thing you can try is using the 0.12-wip branch. You will need to know a little about git and Ruby's gem command to get it going. Because it isn't released yet, you can't use gem install, but google for "build gem from source" and you should be able to figure it out.

It uses a much better serial library. That may work at 9600. I've never tested at 9600 to be honest.
