Hi there, my son and I have just started working with Pixy5 through an Arduino Uno, and have installed the Arduino IDE software, identified the USB port and successfully run the hello_world program. However, when we open PixyMon, it indicates “Error: no Pixy devices have been detected.”
Any advice for how to get PixyMon to recognize and use the Pixy5 through the Arduino Uno? This is a 64-bit MacBook Pro running OSX 10.6.8. Thanks in advance for any advice.

Hi Roger,
Sorry for your troubles. Can you try going through this “Troubleshooting Guide”:http://cmucam.org/projects/cmucam5/wiki/I_get_the_message_“No_Pixy_devices_have_been_detected”_in_PixyMon? Please let me know how it goes.
Scott
Will do - thank you.

Hi Roger,
Are you trying to access the Pixy through PixyMon like this?
Pixy --> Arduino --> USB Cable --> Computer --> PixyMon
If so, you will need to plug a USB cable directly into the USB port on the Pixy to communicate with PixyMon. Like this:
Pixy --> USB Cable --> Computer --> PixyMon
To communicate with the Arduino, see this page http://www.cmucam.org/projects/cmucam5/wiki/Hooking_up_Pixy_to_a_Microcontroller_like_an_Arduino
Hope I could help, Jaimyn 
Hi Jaimyn,
I am using the first method (with Arduino one) as what you said, and I wonder if it is possible use that method to see the real-time image on the Pixymon. So far, I have obtained the messages printed in the serial monitor on the Arduino IDE. However, when I start up pixymon I will get a message “Error: no Pixy devices have been detected” which is the same situation as what Roger metioned.
Looking forward to any reply and thank you.

Hello Zou,
In order to talk to Pixy with PixyMon, you need to hook a USB cable to Pixy, as described in the PixyMon pages, such as:
http://cmucam.org/projects/cmucam5/wiki/Installing_PixyMon_on_Windows_Vista_7_or_8
You can also have a USB cable going to your Arduino, so you can see what your Arduino is doing, for example, when it’s running the hello_world (or similar) sketch. So you have have 2 USB cables in this case: one USB cable goes directly to your Pixy; the other goes directly to your Arduino. With 2 cables you can see what’s going on via PixyMon as well as what’s going on with your Arduino.
If you are having trouble with Pixymon (Error: no PIxy devices have been detected), please check out this troubleshooting guide:
