Support for Pixy Cam for EV3 (maybe NXT)

[bjost2s]

Integration of PixyCam as I2C-Sensor with different modes The PixyCam is a combined Imagesensor and computation unit, which detects color blobs. This imageprocessing unit can be used as Sensor for LEGO MINDSTORMS systems, via I2C interface. Detecting the biggest blob the PixyCam provides several information which are implemented as sensormodes:

• ID ( Up to 7 IDs can be trained with colored objects)
• X-, Y-Coordinate of the blob
• Hight and Width of the blob Each of these values is provided as integer.

Create Block (Blockly)

• Create configurationblock
• Create Expert-block

Integrate Pixy-blocks into OR-Server

Integrate Pixy-classes into Lejos and EV3-dev
