This is Python API for Agilex Robotics

This is a python API for CAN communication with Agilex Robotics

Installation

Notes:

Make sure that python version >=3.4. if you have python3 and python2 ,please use python3

Communication protocol

pip

$ pip3 install pyagxrobots

Notes:

Make sure that pip3 version >= 9.0.0.

cheak the pip3 version

$ pip3 -V     		

updata pip3

$ python3 -m pip install --upgrade pip                 

Setup CAN-To-USB adapter

1. Enable gs_usb kernel module

   $ sudo modprobe gs_usb
   

2. Bringup can device

   $ sudo ip link set can0 up type can bitrate 500000
   

3. If no error occured during the previous steps, you should be able to see the can device now by using command

   $ ifconfig -a
   

4. Install and use can-utils to test the hardware

   $ sudo apt install can-utils
   

5. Testing command

   # receiving data from can0
   $ candump can0
   # send data to can0
   $ cansend can0 001#1122334455667788
   

You can run step 1-5 for the first-time setup and run step 2 to bring up the device each time you unplug and re-plug the adapter.
