Compatibility with Pixy2 camera

The WEEDINATOR project is still progressing nicely and Charmed labs have just released the Pixy2 object recognition camera. I'm singing the praises of the TC275 as loudly as possible everywhere I go, but it would be really great if it could get data from the Pixy2! I would not have bothered asking for the Pixy predecessor, but this version seems an order of magnitude better, with really good vector line recognition which seems to work ok in more severe lighting conditions.


The Pixy2 is a bit pricy at £55, but a lot cheaper and easier than something like the Jetson TX2. Takes about 5 minutes to get going with vectors.


Any chance of getting the TC275 compatible with this device? Here's my error message below:

Thanks!
