What is EV3RT?

EV3RT is an RTOS-based software platform that enables you to develop applications with tough timing constraints for the LEGO® MINDSTORMS EV3.

Features

• TOPPERS/HRP2 real-time operating system
  • Preemptive multitasking with low context-switch overhead (approx. 8 μs)
  • Memory protection (MMU) support to provide high reliability and robustness
  • µITRON-like API based on the TOPPERS NGK specification [Japanese only for now]
• Programming using C/C++
  • GCC ARM Embedded toolchain
  • C standard library (Newlib)
  • Dynamic memory allocation (e.g. malloc) powered by TLSF O(1) allocator
  • EV3RT C API and EV3RT C++ API for sensors, motors, e.t.c.
• Current supported devices
  • UART, I2C, IR and analog sensors
  • EV3 medium/large servo motors
  • Bluetooth PAN (Personal Area Network)
  • Bluetooth SPP (Serial Port Profile)
  • USB (as mass storage device)
  • Speaker, LEDs, LCD and SD card
• Small, light and fast!
  • Platform image < 1 MB, memory footprint < 5 MB, boot time < 5 seconds
• Developer assistant
  • Workspace to manage and build application projects more easily
  • Loader to receive and execute app from USB or Bluetooth at run time
  • Many sample programs (e.g. HelloEV3, Self-balancing robot, Line follower)
  • Multi-platform: Linux, Windows and Mac OS X
