In this project, we reimplemented most of the leJOS sensor API. However, there are some incompatibilities and changes to enhance performance and decrease the complexity of the sensor code that break previously established promises:

• Using multiple SensorModes in parallel doesn't work anymore. This is because for now, we have removed the kernel mode switching from fetchSample() of sensor modes. Instead, the mode switch is performed in the associated get*Mode() functions. This means that once you call one get*Mode() function, you cannot use SensorModes from the other ones. This also means that once you reset the EV3GyroSensor, you have to call get*Mode() once more.

  In the future, if we find a way how to do this efficiently and without making it omplex, we might add support for this feature again. However, we might also keep it the way it is now, as this establishes a different promise - fetchSample only fetches data, and it doesn't touch the sensor mode.

• Most of the BaseSensor functions dealing with sensor modes are effectively broken now. This is caused by the previous point - sensor mode is not switched when using these functions.

• Waiting for multiple values does not work. We do not know how to wait for a new value in ev3dev. This means that IR sensor function reading multiple commands will read only one, otherwise it will throw an exception.

• Motor synchronization is not yet implemented.
