I expect the LED(s) on the micaz (which I don't use myself) are connected to 
digital IO pins.  If so, your only recourse to vary the intensity of the LED 
programmatically is to use PWM (pulse width modulation).  It doesn't appear 
T2 has any built-in support for this capability.

If the micaz's uC has a timer resource supporting PWM (probably does) and the 
LED(s) is/are connected to IO pin(s) that connect to the timer, you could 
build a component to do what you want.  Writing a PWM component is probably a 
task of moderate difficulty.
