HAL stands for Hardware Abstraction Layer and provides a quick and simple way to change pinouts in software and perform basic (and not so basic) "glue logic" functions in RealTime. HAL was designed for the engineer performing basic machine calibration and the system integrator connecting various inputs and outputs such as switches, encoders, servos, and safety checks.
