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.
