Modules§
- Container module for motor types
- Container module for sensor types
- Sound-related functions. It can beep, play wav files, or convert text to speech.
- Utility functions for cpu efficient
wait
commands. Uses thelibc::epoll_wait
that only works on linux systems.
Macros§
- 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.
- Helper macro to create all necessary functions for a button
- Helper to create a new
Device
instance. - Add a sensor mode constant with getter and setter
- The ServoMotor provides a uniform interface for using hobby type servo motors.
- 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.
Structs§
- A wrapper to a attribute file in the
/sys/class/
directory. - Button
ev3
Ev3 brick button handler. Opens the corresponding/dev/input
file handlers. - Helper struct that manages attributes. It creates an
Attribute
instance if it does not exists or uses a cached one. - Led
ev3
The led’s on top of the EV3 brick. - An interface to read data from the system’s power_supply class. Uses the built-in legoev3-battery if none is specified.
- Screen
screen
Represents the device screen. Advanced drawing operations can be performed with theimageproc
crate.
Enums§
- Custom error type for internal errors.
Traits§
- The ev3dev device base trait
- EV3 ports
Type Aliases§
- Helper
Result
type for easy access.
