Control your rainbowduino from Processing

in Share your Work • 3 years ago

Hey guys

I just released my neorainbowduino package. It contains firmware for rainbowduino (from seeedstudio) and arduino, and a Processing library. Send a 8x8 pixel frame to your rainbowduino. I also provided two examples, how to use the library.

I published more information at my blog: http://www.neophob.com/2010/09/neorainbowduino-processing-library/

hope you like it, cheers!

hej,

the library looks really nice

i have problem connection with I2C though.... i get "failed to initialize serial port" in the setup, when i try to run it.

i have the correct firmware on the rainbowduino and arduino.

so i am thinking i fail to initialize with the right I2C adress?

in the line

i2cDest.add(6);

i am adding a destination. but what are the parameters? 6 ports? is the adress 6? should it not be in HEX?

btw, also problems with i2cScanner: it throws a null pointer :( does this mean i have no connection whatsoever?

(I2C wirering is: analogue 4 ->SDA, analogue 5 -> SCL)

best,

jacob

hey jacob, thanks for your reply. please read the included java docs for more information.

in the example my rainbowduino i2c addr. is 6 (6 decimal or hex - does not matter). so if you want to use an example make sure your i2c device has the same address.

if you have connection issues make sure you disconnected the rx/tx lines between arduino and rainbowduino. and if you need further help, check the google code site - there are links available which may help you.

cheers
