Modules

motors

Container module for motor types

sensors

Container module for sensor types

sound

Sound-related functions. It can beep, play wav files, or convert text to speech.

wait

Utility functions for cpu efficent wait commands. Uses the libc::epoll_wait that only works on linux systems.

Macros

dc_motor

The DcMotor provides a uniform interface for using regular DC motors with no fancy controls or feedback. This includes LEGO MINDSTORMS RCX motors and LEGO Power Functions motors.

findable

Helper to create a new Device instance.

sensor_mode

Add a sensor mode constant with getter and setter

servo_motor

The ServoMotor provides a uniform interface for using hobby type servo motors.

tacho_motor

The TachoMotor provides a uniform interface for using motors with positional and directional feedback such as the EV3 and NXT motors. This feedback allows for precise control of the motors.
