Constants and functions related to the Output module.
The NXT output module encompasses all the motor outputs.
Nearly all of the NBC API functions dealing with outputs take either a single output or a set of outputs as their first argument. Depending on the function call, the output or set of outputs may be a constant or a variable containing an appropriate output port value. The constants OUT_A, OUT_B, and OUT_C are used to identify the three outputs. Unlike NQC, adding individual outputs together does not combine multiple outputs. Instead, the NBC API provides predefined combinations of outputs: OUT_AB, OUT_AC, OUT_BC, and OUT_ABC. Manually combining outputs involves creating an array and adding two or more of the three individual output constants to the array.
Output power levels can range 0 (lowest) to 100 (highest). Negative power levels reverse the direction of rotation (i.e., forward at a power level of -100 actually means reverse at a power level of 100).
The outputs each have several fields that define the current state of the output port. These fields are defined in the Output field constants section.
