Raspberry Pi PixyMon

Pixy Software
#1

Anyone have any luck compiling & running PixyMon on a PI3?
I get 'PixyMon: cannot connect to X server ’ when I try to build.

There seems to be no clear answer for this.

Thanks in advance.

Hello Henry,
That sounds like a runtime issue, not a build issue. Do you get this message when you try to run PixyMon? This message is something you would expect to see if you are not running a windowing system (X windows). Are you running from a console of some sort – perhaps through a remote terminal?

Ya I am using terminal. Would be great if I could use this camera via terminal. Haven’t had any luck with it at all on Pi.

Thanks for the reply.

#4

Got it working in GUI, can’t launch from ssh though. Can Iget data from cam via terminal after I set up in gui?

#5

Hello Henry,
I assume you could get PixyMon connected to a remote X server, but I haven’t tried. Perhaps someone on the forum has (?)

You might try ssh with the -X option. I suspect it will require some permission tweaking and setup though.

hello,
the first steps seem to be redundant and outdated because a Pi has already 4 USB ports and Jessie is already installed normally, and so it’s to me:

so it actually starts with paragraph
2.3.1. Install libusb

h1. but I have been asking for C/C++ source code examples, just like for Arduino C Sketch code examples:
where are they? What have you been missing?

(BTW, where is a “quote” button for quote tags in the editor?

#7

Thanks for the reply. It was permission issue and I have build thats works. Is the workflow: train pixy with PixMon, control pixy & retrieve data via libusb ? Is it possible to control the servo via ssh ?

Thanks again, for the reply. I appreciate it.

Great! Did you get Pixymon working remotely using ssh -X? If you did, you can control the servo through PixyMon by issuing by issuing servo move commands from the command/status window. Hit the stop button and type in the following commands into the command/status window:

“rcs_setPos 0 0” moves servo 0 to its clockwise limit
“rcs_setPos 0 1000” moves servo 0 to its counter-clockwise limit
“rcs_setPos 1 0” moves servo 0 to its clockwise limit
“rcs_setPos 1 1000” moves servo 0 to its counter-clockwise limit

You can train Pixy with either button teach or through PixyMon. For Raspberry Pi, USB is the recommended communication mode.

Hope this helps!
