Installation

Notes:

Make sure that python version >=3.6. if you have python3 and python2 ,please use python3

pip

pip3 install pyagxrobots

Notes:

Make sure that pip3 version >= 9.0.0.

pip3 -V     																				 #cheak the pip3 version
python3 -m pip install --upgrade pip                          #updata pip3

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