blinkM example; "EventEmitter memory leak detected."

[kevincannon]

Hi all. Thanks for the reply yesterday :)

I'm trying the BlinkM example code to work. I've gotten Cylon & Firmata working fine, and BlinkM works perfectly well with the BlinkMController, but the i2c stuff is failing when the cylon & firmata combination. Here are the errors.

I noticed someone else having a similar issue a few months back here, but they never said if the issue was resolved for them: https://github.com/hybridgroup/cylon-i2c/issues/17

I think it may be a wiring issue. I've tried it the way it's documented on the BlinkM page (just plugging it in) http://thingm.com/fileadmin/thingm/images/photos/tm_blinkm_arduino_insert.jpg and also on your documentation page: http://cylonjs.com/documentation/drivers/blinkm/ (though without the resistors as it seems they're not needed)

Any thoughts? I tried to follow the advice for the compass in the other thread, but wasn't sure where to apply that code to test it.

Using my Arduino Uno, I have it wired, from left to right on the BlinkM:

(minus) is plugged into the Arduino's GND pin (plus) is plugged into the Arduino's 3.3V pin d is plugged into the Arduino's A4 pin c is plugged into the Arduino's A5 pin

Hope that helps!

Hey - that's great. It's working perfectly now. I'm not quite sure what was happening before. I'm pretty sure I'd tried that too.

Thanks very much for the help - that's really fantastic, I appreciate it a lot :)
