always use the latest development version when requesting help on the forum. To get it, please check using pyDarts from source for on linux or Windows.

Take a look at the common issues downyard.

Please post a message on the sourceforge discussion channel. Please give minimal information to help the community debugging

• your exact pyDarts version (displayed when you launch the software, or when when you downloaded it)
• the output of the terminal running pyDarts with option “–debuglevel=1”
• your configuration (Arduino type, Raspberry if relevant, etc)
• a good description of your issue

You uploaded your configuration file to your Arduino controller? Want to test your wiring and your soldering? Open the Arduino software. Click on “Tools” > “Serial Monitor” like the following picture :

Hit a segment of your board, or create a contact with two pins of your Arduino (use a paper clip on your arduino, for example). Something should appear on the screen like the following picture :

It's possible that pyDarts cannot detect your com port and that calibration fails. Please have a look to the special page pyDarts first run

Delete pyDarts config file and then launch from a terminal (“cmd” in MS windows) :

pydarts --debuglevel=1

When the “board calibration” screen appears, hit a segment, and see what outputs on the terminal.

Note: There is a file named KNOWN_ISSUES in the pydarts package that summarize all the problems already encountered by any of us.

If your pyDarts software won't start, that's probably because you use a x32 system (processor with a 32 bits architecture). pyDarts binary can only run on a x64 architecture. If you really need to use a x32 system, like on a Raspberry Pi, please use pyDarts from source code.

Enjoy !
