Question

So I'm running RAD on my MacBook. I've been able to send serial commands with screen to the device and just light LEDs and simple stuff with the pins connected to the Arduino. However, I have been unable to use any of the blinkM methods that RAD offers. They just fail to compile.

How do I control a blinkM with RAD?

Was it helpful?

Solution

The BlinkM module talks a protocol called I²C. This is supported in the standard Arduino library as part of the Wire library, and the BlinkM_funcs.h header file that's provided with the sample sketches for the device use that.

According to the current RAD todo list, this library hasn't been ported to the RAD IDE yet. It looks like you'll need to use the standard Arduino IDE and C/C++ code to interface with this.
