I’m having the same problems with running the demos as described here http://cmucam.org/boards/10/topics/8178
I built the cable following your instructions, set the interface as LEGOi2c with the standard baudrate and run the default program while pixy is connected to lego and usb PC port; and yet still “the object does not appear on the EV3 screen, just a crescent in the top right hand corner. When I try the chase program, the EV3 just continues forward, and when I run the track program, it just goes in circles.”
I taught pixy to recognize a red bar and it is working, but when it come to lego, nothing.
I have windows 10 on my laptop, the ev3 firmware is 1.09 and pixy is 1.3A
What am I doing wrong?
Thank you for you amazing work and for every hints to solve my issues.
