Installation
------------
This interface has additional dependencies which can be installed using pip and the optional extra ``seeedstudio``. That will include the dependency ``pyserial``::
pip install python-can[seeedstudio]
Interface
---------
::
can.interfaces.seeedstudio.SeeedBus
A bus example::
bus = can.interface.Bus(interface='seeedstudio', channel='/dev/ttyUSB0', bitrate=500000)
Configuration
-------------
::
SeeedBus(channel,
baudrate=2000000,
timeout=0.1,
frame_type='STD',
operation_mode='normal',
bitrate=500000)
CHANNEL
The serial port created by the USB device when connected.
TIMEOUT
Only used by the underling serial port, it probably should not be changed. The serial port baudrate=2000000 and rtscts=false are also matched to the device so are not added here.
