External Handheldpanel & Linux (Raspberry Pi)

Hey Guys and nice Greetings from Germany,

is it possible to run the Software on a Raspberry PI system?

I would create a Handheldpanel with Touchfunctionality and a little 3D Mouse, would be easyer to handle and Teach the Robot. Like a KRC from KUKA.

Any Ideas?!

Greetings Daniel

THX, Chris. GOT IT!


In this RaspberryVersion on Git you only must change the Line in AR2.py where the BAUDRATE is defined. Actual it is at 9600baud but Arduino Communicates with 115200baud.

If i changed it, my Arduino talks to the Raspberry else you got no Communication. 




def setCom():
  global ser
  port = "/dev/ttyACM0" #+ comPortEntryField.get()
  baud = 115200
  ser = serial.Serial(port, baud)



Okay, lets build some Touchscreen Handheld Device :-D.

My plan is it to downsize your Main Softwarevisualisation for a Touchscreen with buttons like Orientation changes from Base to Tool to SingleAxis.

@Wampo I confirm your def setCom() settings work even in case of running the python AR2 script on Ubuntu 16.04. Another thing to do when running on Ubuntu is to run the script with "sudo". For example sudo python3 AR2.py. Else this error will appear: serial.serialutil.SerialException: [Errno 13] could not open port /dev/ttyACM0: [Errno 13] Permission denied: '/dev/ttyACM0'.

@Wampo Thanks for the tip on setting the baud. Were you able to use auto calibrate without it crashing? When I click the button the robot drives to all the limit switches and then stops but the button does not unstick. Program seems to freeze.

I've ported the latest 2.0 version of the software to linux so it is now working for me. I need to update the UI because some of the buttons are cut off but once I'm done doing this I'll send @Chris Annin a copy of it so he can update the main repo. This is so exciting to have my robot finally working after 2+ years of working on it off and on. Thanks again @Chris Annin for creating this project and sharing all the info. (Should note that it works on a raspberry pi but I had to disable xbox controller support. I think that will need a bit of work possibly to work on the Pi.)
