Pixy2 with Raspberry Pi

Pixy Software
#1

I am having Pixy2 with firmware version 3.0.11 and Raspberry Pi with Xubuntu 18.04. I need to interface Pixy2 with Raspberry Pi. I am referring this link.
I get the following error while running the Color Identification Example:

robokits@robokits-desktop:~/pixy2/build/get_blocks_cpp_demo$ ./get_blocks_cpp_demo
=============================================================
= PIXY2 Get Blocks Demo                                     =
=============================================================
Connecting to Pixy2...Error
pixy.init() returned -1

Also, I am not able to access output of Pixy2 using PixyMon while referring to this link. The error is:

robokits@robokits-desktop:~/pixy2/build/pixymon$ ./PixyMon
libEGL warning: DRI2: failed to authenticate

There are a few changes that I made using the PixyMon link. For example, there is no folder such as ‘bin’ in pixy2/build/pixymon/.

Hello,
This might be a permissions issue. Try running get_blocks_cpp_demo or pixymon as root.

e.g.

sudo ./get_blocks_cpp_demo

Hello,
I’m not sure what could be causing this. I’m wondering if your Pixy2 is working correctly. Do you have access to a Windows machine that you can install PixyMon onto and see if your Pixy2 is able communicate (render video,etc)?

Hello,
What kind of host platform are you using? Is it a Raspberry Pi?
