Author Topic: DigiBlink example - how to talk to it? (Read 5942 times)

Got my DSs in the mail yesterday, and I absolutely LOVE them. Wow. So many cool things can be done with this tiny board. First things first though - I complied and downloaded the DigiBlink example, but how do I talk to it on the PC side? Is there a PC app for it? It enumerates as a generic HID device, correct?

Some official command line programs will be out for it soon - in the mean time:

Here is some python to control it: http://cl.ly/300y3k1q0e0R/DigiBlink.zip

Here is an app that connects it to the cheerlights.com project: http://cl.ly/1S0x3q2H1B0X/DigiBilnk-CheerLights.zip

If you\'re a ruby programmer, or interested in learning, you might like to try out the digiusb rubygem: http://rubygems.org/gems/digiusb - it also installs a command line program called \'digiterm\' which works a bit like the serial console in arduino, displaying any strings the digispark writes out and letting you type messages back to it

Just got my digisparks. AWESOME!!! Anyways I\'m trying to get this DigiBlink example to work. I have downloaded the DigiBlink.zip, installed python, and ran it. To my un-surprise it didn\'t work. I\'m chalking this up to me being a c# developer and never having used python. I\'m getting two errors a general syntax error and a \'usb\' module not found error. I have a feeling my problem lies in where I am running the DigiRGB.py script from. Also I am running this on windows. So if anyone could help this python noob I would greatly appreciate it.

metoo - try the DigiBlink program in the main Digispark Arduino IDE download, it is in the Digispark - Example Programs folder.

I got this to work under Ubuntu. The program compiled just fine once I got the development environment fixed. Then, to get the Python program working, I had to install PyUSB version 1.0 (using Python\'s setup.py -- the python-usb package in Ubuntu is 0.4)
sudo apt-get install libusb
git clone https://github.com/walac/pyusb.git
cd pyusb; sudo python setup.py install
The code still needs webcolors, and it seems not to be an Ubuntu package, so:
sudo easy_install webcolors
And finally, you\'ll need to create a 90-digispark.rules which looks like this:
SUBSYSTEMS==\"usb\", ATTRS{idVendor}==\"16c0\", ATTRS{idProduct}==\"05df\", GROUP=\"adm\"
and put it into /etc/udev/rules.d (as root, of course). You should be in the \'adm\' group already on a single-user Ubuntu machine, but check that using groups.
