// Authors: Justin Eltoft based on EX_RGB_Dim by Dan G Ogorchock
|
|
//
|
|
// Summary: EX_NEOPIX is a class which implements the SmartThings "Color Control", "Switch", and "Switch Level" device capabilities.
|
|
// It inherits from the st::Executor class.
|
|
//
|
|
// Create an instance of this class in your sketch's global variable section
|
|
// For Example: st::EX_NEOPIX executor1("rgbSwitch1", PIN_NEOPIX);
|
|
//
|
|
// st::EX_NEOPIX() constructor requires the following arguments
|
|
// - String &name - REQUIRED - the name of the object - must match the Groovy ST_Anything DeviceType tile name
|
|
// - byte pin_neopix - REQUIRED - the Arduino Pin to be used as the one wire bus for neopixels
|
|
