 Pixy can learn seven color signatures, numbered 1-7. Color signature 1 is the default signature. To teach Pixy the other signatures (2-7) requires a simple button pressing sequence. Pixy can learn seven color signatures, numbered 1-7. Color signature 1 is the default signature.

 PixyMon is great for debugging your application. You can plug a USB cable into the back of Pixy and run PixyMon and then see what Pixy sees while it is hooked to your Arduino or other microcontroller — no need to unplug anything.

Line 91: Line 94:
 CCs are useful if you have lots of objects you want to detect and identify, more than could be detected with the seven separate color signatures alone. CCs also improve detection accuracy by decreasing false detections. That is, there is a low probability that specific colors will occur both in a specific order and close together. The drawback is that you need to place a CC on each object you’re interested in detecting. Often the object you’re interested in (yellow ball, purple toy) has a unique color signature and CCs aren’t needed. Objects with CCs and objects without CCs can be used side-by-side with no problems, so you are free to use CCs for some objects and not others. CCs are useful if you have lots of objects you want to detect and identify, more than could be detected with the seven separate color signatures alone.

 CCs give you an accurate angle estimate of the object (in addition to the position and size). This is a computational “freebie” that some applications may find useful. The angle estimate, decoded CCs, regular objects and all of their positions and sizes are provided at 50 frames per second. CCs give you an accurate angle estimate of the object (in addition to the position and size).

 CCs might be particularly useful for helping a robot navigate. For example, an indoor environment with CCs uniquely identifying each doorway and hallway would be both low-cost and robust. CCs might be particularly useful for helping a robot navigate.
